The upper level of the bridge has four lanes of automobile traffic, consisting of two roadways with two lanes in each directions. It provides a view of the bridge's cantilever truss structure and the New York skyline. Although the two upper level roadways both end at Thomson Avenue on the Queens side, they diverge in opposite directions on the Manhattan side. The lanes used by westbound traffic, located on the northern side of the bridge, lead north to 62nd and 63rd Streets. On the other hand, the lanes normally used by eastbound traffic are located on the southern side of the bridge lead south to 57th and 58th Streets.

Queensboro Bridge | Levels
The Queensboro Bridge is a two-level double cantilever bridge, with separate cantilevered spans over channels on each side of Roosevelt Island joined by a fixed central truss. In all it has five spans, including approaches between the cantilevered sections and each terminus. Their lengths are as follows: Until it was surpassed by the Quebec Bridge in 1917, the span between Manhattan and Roosevelt Island was the longest cantilever in North America.
Queensboro Bridge | Description
The bridge's upper level originally contained two pedestrian walkways and two elevated railway tracks (which connected a spur of the IRT Second Avenue Elevated Line in Manhattan to the Queensboro Plaza station in Queens). Three lanes of roadway were installed on the south side of the upper level in 1931, replacing the former upper-level walkway. All service on the Second Avenue Elevated was discontinued in 1942. From 1955 to 1958, two additional lanes were built on the upper level. The upper-level ramps on the Queens end of the bridge were built during the same time. The lower deck originally hosted four motor traffic lanes, and what is now the "outer roadway" and pedestrian walk were two trolley lanes.
Queensboro Bridge | Early days
The roadway to 57th and 58th Streets is used as a westbound high-occupancy vehicle lane during rush hours. The lower level has five vehicular lanes, the inner four for automobile traffic and the southern outer lane for automobile traffic as well, used exclusively for Queens-bound traffic. The North Outer Roadway was converted into a permanent pedestrian walk and bicycle path in September 2000.
Queensboro Bridge | Levels
In addition to the two elevated railway tracks, the bridge also had four streetcar tracks. The following Queens lines operated over the bridge: One Manhattan line operated over the bridge, the Third Avenue Railway's 42nd Street Crosstown Line from 1910 to 1950.
Queensboro Bridge | Rail tracks
The first phase involved renovating the Queens span and approach ramps, as well as replacing the suspender cables. On the Queens side, an exit ramp from westbound I-278 to 31st Street necessitated the destruction of the entrance to the southern sidewalk. The second phase involved renovating the Bronx span and approach ramps. The third phase involved renovating the Manhattan span and approach ramps. Work on replacing the Queens span's suspender cables and adding an orthotropic deck to the Queens suspension span started in 2000. At some point in the past, a sign on the bridge informed travelers, "In event of attack, drive off bridge," "New York Times" columnist William Safire wrote in 2008.
Triborough Bridge | Later history
The streetcars used the outermost roadways of the Queensboro Bridge's lower level, and ran to an underground terminal between 59th and 60th Streets. These tracks were shared with the Third Avenue Railway's 42nd Street Crosstown Line. Other streetcar lines ran in the inner roadways of the lower level. The bridge was also shared with elevated rapid transit service between the Queensboro Plaza station (now a subway station) and the Second and Third Avenue elevated lines. The southern (eastbound) roadway has since been converted to vehicular use, while the northern (westbound) roadway is now a pedestrian and bike path.

Buck and Henry Hornbostel, designers of the Williamsburg Bridge. Construction soon began, but it would take until 1909 for the bridge to be completed due to delays from the collapse of an incomplete span during a windstorm, and from labor unrest, which included an attempt to dynamite one span. The bridge opened for public use on March 30, 1909, having cost about $18 million and 50 lives. There was a ten-cent toll to drive over the bridge. The bridge's ceremonial grand opening was held on June 12, 1909. At the time, it was the fourth longest bridge in the world.
Queensboro Bridge | Construction
The bridge, including approaches, is long, its main span is , and its deck is wide. Measured from high water, the height at the center of the bridge is above the river and each tower is tall. The structure is unconventional among suspension bridges in having its main span hanging from cables in the usual manner but its side spans being supported entirely by their trusswork. The Brooklyn landing is between Grand Street and Broadway, which both had ferries prior to the bridge's construction. The five ferry routes operated from the landings went out of business by 1908. The bridge once carried New York State Route 27A.
Williamsburg Bridge | Description
The Williamsburg Bridge is a suspension bridge in New York City across the East River connecting the Lower East Side of Manhattan at Delancey Street with the Williamsburg neighborhood of Brooklyn at Broadway near the Brooklyn-Queens Expressway (Interstate 278). Completed in 1903, it was the longest suspension bridge span in the world until 1924. The bridge is one of four toll-free vehicular bridges connecting Manhattan Island and Long Island. The others are the Queensboro Bridge to the north, and the Manhattan and Brooklyn Bridges to the south. The Williamsburg Bridge once carried New York State Route 27A and was planned to carry Interstate 78, though the planned I-78 designation was aborted by the cancellation of the Lower Manhattan Expressway and Bushwick Expressway.
Williamsburg Bridge | Introduction
The Brooklyn Bridge is an icon of the city itself. The towers of the Brooklyn Bridge are built of limestone, granite, and Rosendale cement, and their architectural style is neo-Gothic, with characteristic pointed arches above the passageways through the stone towers. This bridge was also the longest suspension bridge in the world from its opening until 1903, and is the first steel-wire suspension bridge. The Queensboro Bridge is an important piece of cantilever architecture. The Manhattan Bridge, opened in 1909, is considered to be the forerunner of modern suspension bridges, and its design served as the model for many of the long-span suspension bridges around the world; the Manhattan Bridge, Throgs Neck Bridge, Triborough Bridge, and Verrazano-Narrows Bridge are all examples of Structural Expressionism.

The lower level is currently used for train storage. Unused construction is also present near the west end of the Queensboro Bridge. The original plan there was to build two one-track tunnels under 59th and 60th Streets, rising onto the bridge to Queens. However, on July 28, 1915, the Public Service Commission approved a change of plans requested by the New York City Board of Estimate to place both tracks under 60th Street and cross the East River in the 60th Street Tunnel, because of concern whether or not the bridge could handle the weight of all-steel subway trains. A piece of the 59th Street tunnel had already been built, concurrent with the construction of the IRT Lexington Avenue Line, and became a walkway connecting the two side platforms of the IRT's 59th Street station.

Triborough Bridge | Introduction
Workers later added several support towers on either side of the main span to supplement the suspension towers. In 1969, inspectors found varying degrees of corrosion under the bridge's outer roadways. A 1978 study of the Williamsburg Bridge, as well as of five other bridges in New York City, found that there were varying degrees of corrosion on the main cables' individual strands. Cracks were also found in the bridge structure itself. Out of the six bridges examined in 1978, the Williamsburg Bridge was the only crossing that was found to have corroded suspension cables. A subsequent study concluded that the bridge needed either new cables or a replacement.
Williamsburg Bridge | Rehabilitation
The road deck was re-opened only in a southbound (towards Gateshead) direction and carries only buses and taxis; the one-way operation is required because of width considerations after protection to the structural members was inserted. Pedestrians and cyclists use the bridge freely. Railway traffic continues in full use of the bridge, although the majority of mainline trains use the King Edward VII bridge for reasons of convenience.
High Level Bridge | The present day
The East River span, a suspension bridge across the Hell Gate of the East River, connects Queens with Wards Island. It carries eight lanes of Interstate 278, four in each direction, as well as a sidewalk on the northeastern side. The span connects to Grand Central Parkway, and indirectly to the Brooklyn–Queens Expressway (I-278), in Astoria, Queens. Originally it connected to the intersection of 25th Avenue and 31st Street; the former was later renamed Hoyt Avenue. The suspension span was designed by chief engineer Othmar Ammann. The span was originally designed to be double-decked, with eight lanes on each deck.

The first "Queenston-Lewiston Bridge" was built in 1851 by engineer Edward Serrell and wrecked by wind in 1864 (or 1854). Some of the cables were still in place as late as 1895. The road deck span was about . The suspension bridge design was unusual because the cables were attached to the cliff with only small towers. This made the road deck span shorter than the cable span of . A second bridge called the "Queenston-Lewiston Bridge", a suspension bridge was later constructed. Located north, the suspension bridge was originally built near the location of the present-day Rainbow Bridge, and was moved to Queenston in 1898 by R.S.

Although a second deck for the Brooklyn Bridge was proposed, it was thought to be infeasible because doing so would overload the bridge's structural capacity. The first new bridge across the East River, the Williamsburg Bridge, opened upstream in 1903 and connected Williamsburg, Brooklyn, with the Lower East Side of Manhattan. This was followed by the Queensboro Bridge between Queens and Manhattan in March 1909, and the Manhattan Bridge between Brooklyn and Manhattan in December 1909. Several subway, railroad, and road tunnels were also constructed, which helped to accelerate the development of Manhattan, Brooklyn, and Queens. Though tolls had been instituted for carriages and cable-car customers since the bridge's opening, pedestrians were spared from the tolls originally.

Bronx–Whitestone Bridge | Introduction
Queens is connected to the Bronx by the Bronx–Whitestone Bridge, the Throgs Neck Bridge, the Triborough Bridge (also known as the Robert F. Kennedy Bridge), and the Hell Gate Bridge. Queens is connected to Manhattan Island by the Triborough Bridge, the Queensboro Bridge, and the Queens–Midtown Tunnel, as well as to Roosevelt Island by the Roosevelt Island Bridge. While most of the Queens/Brooklyn border is on land, the Kosciuszko Bridge crosses the Newtown Creek connecting Maspeth to Greenpoint, Brooklyn. The Pulaski Bridge connects McGuinness Boulevard in Greenpoint to 11th Street, Jackson Avenue, and Hunters Point Avenue in Long Island City.

Construction on what was then known as the "East River Bridge", the second to span it, began in 1896 after approval by the Governor of New York on May 27, 1895. The new bridge was to be built north of the Grand Street Ferry, terminating at Delancey and Clinton Streets on the Manhattan side and at South Fifth Street and Driggs Avenue on the Brooklyn side. Leffert L. Buck was the chief engineer, Henry Hornbostel was the architect, and Holton D. Robinson was the assistant engineer. Engineers first constructed caissons on either side to support the future bridge. The caisson on the Manhattan side was completed in May 1897, upon which time the caisson on the Brooklyn side was launched.
Williamsburg Bridge | Construction
At ground-level was an additional terminal for through-trolley service from the New York Railways Company and Third Avenue Railway, whose lines traveled from Manhattan along the north side of the bridge to the Washington Plaza trolley terminal in Williamsburg, Brooklyn. The covered exit stairs from the subway and underground terminal led directly to the shelters serving the Manhattan surface trolleys. Both the staircases and shelters were designed with terracotta features. The exit stairs were designed as kiosks constructed of concrete, and finished with blue and white tiling.
Williamsburg Bridge Trolley Terminal | Surface terminal
The Williamsburg and Manhattan bridges are the only suspension bridges in New York City that still carry both automobile and rail traffic. The Williamsburg once held four trolley tracks in addition to the two subway tracks currently on the bridge that connect the New York City Subway's BMT Nassau Street Line and BMT Jamaica Line. Two tracks on the south side carried streetcars from the Brooklyn side: Two north-side tracks carried Manhattan streetcars:

However, as late as August 1973, a separate passenger elevator ran during the work week from near the Queens end of the bridge to Welfare Island via the Welfare Island Elevator Storehouse, which was described at the time as "clean but gloomy".
Queensboro Bridge | Early days
The Manhattan approach to the bridge is supported on a series of Guastavino tile vaults which formed the elegant ceiling of the former Food Emporium Bridge Market and the restaurant Guastavino's, located under the bridge. Originally, this open air promenade was known as Bridgemarket and was part of Hornbostel's attempt to make the bridge more hospitable in the city. In February 2020, it was announced that Trader Joe's is planning to open a supermarket in this space.

Each bridge carries an orthotropic deck atop steel box girders. Each bridge spans a total of , excluding approaches, as a three-span girder bridge, with a main span flanked on each side by a side span. Including the south and north approaches, the total length of each bridge is . The deck is coated with an epoxy asphalt wearing surface. The main span includes a central , drop-in section which was lifted in place by the "Marine Boss" floating crane. The drop-in span is supported on each side by a section cantilevered off the pier. The Bridges feature a vertical clearance above the average low tide mark and provide three lanes of traffic in each direction with a wide sidewalk outboard of the traffic lanes.
Queensway Twin Bridges | Design
The Triborough Bridge is made of four segments. The three primary spans traverse the East River to Queens; the Harlem River to Manhattan; and Bronx Kill to the Bronx, while the fourth is a T-shaped approach viaduct that leads to an interchange plaza between the three primary spans on Randalls Island. The Queens arm of the viaduct formerly crossed Little Hell Gate, a creek located between Randalls Island to the north and Wards Island to the south. Excluding elevated ramps, the segments are a total of long, with a span between the Bronx and Queens, and a span between Manhattan and the interchange plaza.
Triborough Bridge | Description
After years of decay and corrosion, an extensive renovation of the bridge began in 1987 and completed in 2012, having cost over $300 million. For a brief period in 1997, the traffic directions of the upper-level roadways were reversed during rush hours so that the upper level used a left-hand traffic pattern. Manhattan-bound traffic used the southern roadway while Queens-bound traffic used the northern roadway. After residents of the Upper East Side voiced concerns about severe rush-hour congestion, this traffic pattern was discontinued, and the south-side walkway on the lower level was converted to a Queens-bound vehicular lane during the evening rush hour.
Queensboro Bridge | Since the 1980s
The bridge has two main spans, since there is an east and west channel in the Hudson River at this point.
Kingston–Rhinecliff Bridge | Introduction
The railways used the upper deck, and wagons, livestock and pedestrians used the lower deck. This bridge was long, and was located near the Rock Island shore. During the 1880s, it accommodated horse-drawn trolley cars and electric trolleys; this tradition was continued on the fourth bridge until 1940.
Government Bridge | Third bridge
The New York State Department of Transportation applied for funding to rebuild the bridge, which was projected to cost $250 million and take ten years. Every third rope in the suspension had already been replaced in 1985. However, more than 200 cables in the suspension had snapped, and pieces of concrete were falling from the bridge. The bridge's structural integrity was rated as 1.6 out of a scale of 1 to 7.
Williamsburg Bridge | Rehabilitation
The bridge spans the Forth between the villages of South Queensferry and North Queensferry and has a total length of with the double track elevated above the water level at high tide. It consists of two main spans of , two side spans of , and 15 approach spans of . Each main span consists of two cantilever arms supporting a central span truss. The weight of the bridge superstructure was , including the 6.5 million rivets used. The bridge also used of granite. The three great four-tower cantilever structures are tall, each tower resting on a separate granite pier.

Some double-decked bridges only use one level for street traffic; the Washington Avenue Bridge in Minneapolis reserves its lower level for automobile and light rail traffic and its upper level for pedestrian and bicycle traffic (predominantly students at the University of Minnesota). Likewise, in Toronto, the Prince Edward Viaduct has five lanes of motor traffic, bicycle lanes, and sidewalks on its upper deck; and a pair of tracks for the Bloor–Danforth subway line on its lower deck. The western span of the San Francisco–Oakland Bay Bridge also has two levels. Robert Stephenson's High Level Bridge across the River Tyne in Newcastle upon Tyne, completed in 1849, is an early example of a double-decked bridge.

The approach spans have cross girders, spaced apart, while the lifting girder features cross girders spaced at intervals of . The bridge abutments are of cellular concrete construction. Pier 1, 2, 5 and 6 comprise five reinforced concrete circular caisson piles, formed as piers. They have a diameter of and are spaced at intervals of between centres. A reinforced concrete cap, which has a height of and a depth of 6 feet, sits above the piers. Below the level of river bed is a cast iron subway, which links piers 3 and 4 of the bridge’s lifting span.

Double-decked (or double-decker) bridges have two levels, such as the George Washington Bridge, connecting New York City to Bergen County, New Jersey, US, as the world's busiest bridge, carrying 102 million vehicles annually; truss work between the roadway levels provided stiffness to the roadways and reduced movement of the upper level when the lower level was installed three decades after the upper level. The Tsing Ma Bridge and Kap Shui Mun Bridge in Hong Kong have six lanes on their upper decks, and on their lower decks there are two lanes and a pair of tracks for MTR metro trains.

Horns Bridge was all the more striking because the congestion was three-dimensional: "At ground level:" "At middle level:" "At high level" The best place to start to gain an impression of the pre-1960 Horns Bridge is a map. An OS map from the 1940s gives a good idea, with a range of other old Black and White maps fleshing out detail. Maps are two-dimensional, the aerial photograph in "Gt Central North of Nottingham" gives an idea of scale, complexity and height, which "The Changing Face of Chesterfield" and the DVD complement.

Design and construction of a replacement bridge commenced in 1939, due to concerns that the original bridge would not hold up to extra loading and traffic caused by transport demands of World War II. Work commenced on the new bridge in July 1940 and despite best efforts it was not completed until after the war finished, opening for traffic on 1 July 1946. The new bridge was positioned to the west or upstream of the original bridge and consists of eight spans in three different lengths and piers sunk to depths of up to . New tunnels were bored through Long Island to the south and Cogra Point on the northern approach.

The western leg of the Queensboro Bridge is flanked on its northern side by the freestanding Roosevelt Island Tramway. The bridge was, for a long time, simply called the Queensboro Bridge, but in March 2011, the bridge was officially renamed in honor of former New York City mayor Ed Koch. The Queensboro Bridge is the northernmost of four toll-free vehicular bridges connecting Manhattan Island to Long Island, along with the Williamsburg, Manhattan, and Brooklyn bridges to the south. It is the first entry point into Manhattan in the course of the New York City Marathon and the last exit point out of Manhattan in the Five Boro Bike Tour.
Queensboro Bridge | Introduction
Interior clearance is only , enforced by metal height restrictors near the portals. Two sets of heavy timber planks serve as the top and bottom chords, with a secondary lower chord at deck level. Twelve-inch (30 cm) diagonals, fastened at each intersection by two-inch (5 cm) treenails, radiate out from the middle to either end. They are supplemented by additional diagonals at the ends and four wooden buttresses along the exterior on either side.
Beaverkill Bridge | Structure
By October 1935, the Queens approach and the Randalls and Wards Islands viaduct was nearly complete. Vertical suspender cables had been hung from the main cables of the Queens suspension span, and the steel slabs to support the span's roadway deck were being erected. However, progress on the Bronx and Manhattan spans had not progressed as much: the concrete piers supporting Bronx span were being constructed, and the site of the Manhattan span was marked only by its foundations. The deck of the Queens suspension span was completed the following month. In November 1935, a controversy emerged over the fact that the Triborough Bridge would use steel imported from Nazi Germany, rather than American producers.
Triborough Bridge | Significant progress
The High Level Bridge was an important node on the railway network, and as branch line passenger services and mineral traffic built up it became a bottleneck. This was exacerbated by the location of the main locomotive depot for Newcastle being located at Gateshead; as many train services changed engines at Newcastle this generated a huge number of light engine movements to and from the depot across the bridge. At the beginning of the twentieth-century proposals were brought forward to build a second, rail-only bridge. This became the King Edward VII Bridge, located a few hundred yards to the west of the High Level Bridge.
High Level Bridge | A second crossing
In the original configuration, the station had eight tracks and four tracks per each level. Originally, the IRT used both sides of the current platforms, and the BMT used now-demolished platforms north of the current platforms, also double-decked. The south side of the IRT platforms was used by the Flushing Line, as today; the north side was used by Astoria trains, but instead of going through the 60th Street Tunnel, they went over the Queensboro Bridge to the elevated IRT Second Avenue Line. Double crossovers south (lower tracks) and north (upper tracks) of the platforms allowed trains from either side to switch to the other line after leaving the station.

The bridge is a cable-stayed structure, with three towers each high. Including approaches, the overall length of the bridge is ; at opening, it is the longest triple tower cable-stayed bridge in the world. The bridge carries motorcycles, cars and heavy goods vehicles, while public transport, cyclists and pedestrians use the existing bridge. Wind shielding has been built into the design, to enable use of the bridge in high winds, which regularly led to restrictions on the existing bridge. The bridge was closed for the first time on 11 February 2020, 30 months after opening, due to accumulations of ice on the towers.

The bridge carries the Q32 local bus route operated by MTA New York City Transit and the Q60 and Q101 local bus routes operated by the MTA Bus Company. The bridge also carries 20 express bus routes in the eastbound direction only: the MTA Bus Company's , and New York City Transit's X63, X64, and X68. (These bus routes use the Queens-Midtown Tunnel for westbound travel.)

Each set of three spans consists of two simply supported end spans which continue as cantilevers approximately 1/5 span into the middle span. The central 3/5 span sections are simply supported drop in spans supported by halving joints. The main span is a structurally independent lifting span. The bearings are inset from the end lifting beams. Spans 1, 3, 5 and 7 are c/c of bearings. Spans 2 and 6 are , with halving joints from both end and a suspended span of . The central lifting span, Span 4, is c/c of bearings, with cantilevers of either end to the lifting cross girders.

The Queensboro Bridge, also known as the 59th Street Bridge – because its Manhattan end is located between 59th and 60th Streets – and officially named the Ed Koch Queensboro Bridge, is a cantilever bridge over the East River in New York City. It connects the neighborhood of Long Island City in the borough of Queens with the Upper East Side in Manhattan, passing over Roosevelt Island. The bridge was completed in 1909. The Queensboro Bridge carries New York State Route 25, which terminates at the bridge's western end in Manhattan, and also once carried NY 24 and NY 25A.
Queensboro Bridge | Introduction
The third bridge (the "modern bridge") actually consists of two bridges, a vehicular bridge and a pedestrian bridge. The vehicular bridge's plan was originally designed to connect York and St. Mary Avenues to Provencher Boulevard, but it was cancelled in 1997. The lands for the St. Mary–York–Provencher connection were used for the construction of the Canadian Museum for Human Rights. The vehicular bridge was constructed in 2001 and completed in September 2003. The pedestrian bridge was constructed later, and was completed the same year.

In between the loops were seven low-level island platforms, slightly raised from track level. Each platform had 12 foot-wide staircases leading to the street. Each loop could hold two trolley cars, with a trolley stopping at the west end of the platform to discharge Manhattan-bound passengers, then moving up to the east end to pick up Brooklyn-bound passengers. The terminal was designed with both electrical incandescent lighting and vaults that allowed natural light to enter the station. Below are the list of routes that served each loop:

The first bridge on this site was constructed by the New York and Harlem Railroad in 1841. It was composed of four -long box truss spans, three of which were fixed iron spans, while the remaining span was a wooden swing span. In the closed position, the bridge had a clearance of only seven feet above mean high water. Masonry piers supported the four box-truss spans. In 1867, the wooden drawbridge was replaced with an iron one that gave a clearance of 50 feet. By the 1880s, the bridge was crossed by more than 200 trains a day.

These large bridges had to be metal and supplied from England, a very expensive import cost to the successive colonial governments. Both Chief Engineers were British so they chose the widely used wrought iron lattice truss bridge in the half-through form. Twelve of these were built for the railways and 24 for roads. These two sets of iron lattice bridges are the most significant group of bridges of the colonial period. A high percentage are extant and still in use, eleven on railway bridges and eighteen on road bridges.
Macdonald River railway bridge, Woolbrook | History
The design, foundation work and fabrication of the new bridge were undertaken by the New South Wales Government Railways and over 500 men worked on the project, with six dying during construction. A plaque commemorating the lives lost is at the southern end of the bridge, at the northern portal of the 1946 tunnel through Long Island. The spans for the new bridge were constructed adjacent to the bridge site on the northern side of Long Island, raised to the correct height, placed onto barges and floated out to the piers at high tide. Upon completion of the new bridge, the old bridge was removed, however the sandstone capped piers remain to this day.
Hawkesbury River railway bridge | Second bridge
In 1892, the third Sixth Street Bridge was built by an engineer named Theodore Cooper for the Union Bridge Company. The main spans were long, each having through trusses of the camel-back type with upward-angled upper chords, and were twice as wide as the previous bridge. In 1927 the bridge had to be taken apart because the steelwork was too brittle for safety. So in 1927, the main spans were somewhat trimmed down temporarily from their height which were then lowered onto barges and floated down the Ohio River to the back channel of Neville Island to become part of the Coraopolis Bridge.

To accommodate the bridge's approaches, 600 houses were demolished in total, including 330 on the Manhattan side and 270 on the Brooklyn side. More than 10,000 people were evicted from these houses during construction.

The Brooklyn Bridge, completed in 1883, was the first bridge to span the East River, connecting the cities of New York and Brooklyn, and all but replacing the frequent ferry service between them, which did not return until the late 20th century. The bridge offered cable car service across the span. The Brooklyn Bridge was followed by the Williamsburg Bridge (1903), the Queensboro Bridge (1909), the Manhattan Bridge (1912) and the Hell Gate Railroad Bridge (1916). Later would come the Triborough Bridge (1936), the Bronx-Whitestone Bridge (1939), the Throgs Neck Bridge (1961) and the Rikers Island Bridge (1966). In addition, numerous rail tunnels pass under the East River – most of them part of the New York City Subway system – as does the Brooklyn-Battery Tunnel and the Queens-Midtown Tunnel.

Due to its height, it could "scarcely be crossed for the first time without something like a feeling of terror". The bridge allowed the rail line to continue north to Kingston.

Thus, though the span is straight, the overall crossing takes a distinctive curving alignment. The causeways were widened to the Trans-Canada Highway standard width of 3 lanes (2 travel lanes and emergency shoulders) and lengthened to narrow the span to roughly half that of the railway bridge.

The new bridge is less ornate though perhaps more functional, but has the effect of splitting the downtown area and was made possible only by the demolition of half of the downtown Rondout, New York historic district. The old bridge is considered structurally deficient by both agencies and for that reason it is limited to carrying vehicles of 3 tons or less. According to a structures engineer for the state DOT, an inspection of the main cables will be carried out in the spring of 2008 by the engineering firm of Modjeski & Masters which specializes in signature (unusual) & suspension bridges.

Buck and engineer L.L. Buck, after the completion of the Rainbow Bridge's predecessor, the Upper Steel Arch Bridge. The suspension bridge was dismantled in 1963 after the current bridge was completed and opened. Reminders of the earlier bridge are still visible in the area. First is two columns that lie within the Earl W. Brydges Artpark State Park. Second is the original plaque, now located midspan alongside the road, right at the border between the two countries. The plaque is flanked by a US and a Canadian flag. The supports are part of Owen Morrell's Omega, a steel sculpture and observation platform added in 1981.

The next downstream bridge has considerably older predecessors going back to the early medieval period and is the only other of the reach, Kingston Bridge, London — it is pale brick and stone only and of taller design with two extra arches. The next bridge upstream was replaced in 2013 with a single-span bridge heading up the Thames, a tied arch bridge, Walton Bridge.

These large bridges had to be metal and supplied from England, a very expensive import cost to the successive colonial governments. Both Chief Engineers were British so they chose the widely used wrought iron lattice truss bridge in the half-through form. Twelve of these were built for the railways and 24 for roads. These two sets of iron lattice bridges are the most significant group of bridges of the colonial period. A high percentage are extant and still in use, 11 on railways and 18 on roads. The current railway lattice bridges are:

At the foot of the bridge in Williamsburg between South 5th place and Havemeyer Street in Brooklyn are three public areas that, collectively, comprise the Williamsburg Bridge Plaza, also known as Washington Plaza or George Washington Monument Park. It contains Continental Army Plaza and LaGuardia Playground, both operated by the Parks Department, as well as the Williamsburg Bridge Plaza Bus Terminal, which serves numerous bus lines to Brooklyn and Queens. The plaza is named after the large statue of George Washington in Continental Army Plaza erected in 1906.

Perry. Each tower was supposed to have two ornate arches at the top, similar to the Brooklyn Bridge, and was to have been supported by four legs: two on the outside and two in the center. A 1932 article described that each tower would be made of 5,000 tons of material, including 3,680 tons of steel. The final design of the suspension towers, by Ammann, consists of comparatively simple cross bracing supported by two legs. The tops of each tower contain cast iron saddles in the Art Deco style, over which the bridge's main cables run. These are topped by decorative lanterns with red aircraft warning lights.

This two-level station has two island platforms (one on each level) and four tracks. It stands over the south (railroad east) side of the roadway, but formerly spanned the whole plaza. Trains running into Queens stop on the upper level and Manhattan-bound trains below. On both levels, the BMT Astoria Line (which to the south joins with the 60th Street Tunnel Connection and heads through the 60th Street Tunnel to the BMT Broadway Line) uses the north track and the IRT Flushing Line uses the south track. , the station is being renovated by NYCTA employees (as opposed to an outside contractor).

The first bridge on this position, constructed on wooden piers, was built in 1810–12. The roadway was level with the east bank, meaning that the bridge had to be reached via a ramp from the lower west bank. This bridge was replaced in 1824. Over the first few years of the second bridge's existence, buildings began to be constructed along the bridge, a situation legally permitted due to fact that the river is not navigable at this point. In 1827 a market was constructed on the north side, its west end resting on the Front Street wall and its east end supported by the westernmost pier of the bridge.

The Hillsborough River Bridge is a bridge crossing the Hillsborough River estuary between Charlottetown and Stratford in Queens County, Prince Edward Island. The current road bridge, built in 1962, replaced a 1905 rail bridge crossing the same span which was known by the same name. The first bridge was built by the Prince Edward Island Railway to complete a rail line from Charlottetown to Murray River. The single-lane bridge opened in 1905, and incorporated iron spans from two bridges in Miramichi, New Brunswick built about 30 years earlier. As rail service in the province was converted to standard gauge and heavier service, use of the bridge declined until it was deemed unsafe for all traffic in the 1950s.
Hillsborough River Bridge | Introduction
With its Gothic-revival double-arched stone towers and diagonal suspension wires, the Brooklyn Bridge is one of the city's most recognized architectural structures, depicted by artists such as Hart Crane and Georgia O'Keeffe. The Brooklyn Bridge's main span is , and was the longest in the world when it was completed. The Williamsburg Bridge and Manhattan Bridge are the two others in the trio of architecturally notable East River crossings. The Ed Koch Queensboro Bridge, which links Manhattan and Queens, is an important piece of cantilever bridge design. The borough of Staten Island is connected to Brooklyn through the Verrazano-Narrows Bridge.

Connolly also said that a bridge between Queens and Manhattan needed to be built further downstream, closer to the Queensboro Bridge, which at the time was the only bridge between the two boroughs. The Port of New York Authority included the proposed Tri-Borough Bridge in a report to the New York state legislature in 1921. The following year, the planned bridge was also included in a "transit plan" published by Mayor John Francis Hylan, who called for the construction of the Tri-Borough Bridge as part of the city-operated Independent Subway System (see ). In March 1923, a vote was held on whether to allocate money to perform surveys and test borings, as well as create structural plans for the Tri-Borough Bridge.

Four different concepts are being considered for a new bridge. Four alternates, that use two of the four bridge concepts, differ depending on if one-way or two-way service roads are chosen. Alternate 1 shows a preference for bridge concept A. Alternate 2 shows a preference for bridge concept C with continuous service roads across the bridge. All the bridge profiles use models with a 95' finished grade elevation, 57.10' lower than the current bridge, and a vertical clearance of 73' that is 62' lower than the current bridge. All bridge models show a 3% grade on the west side. The east side would be 3% for bridge profile 1, with 2.25% for profile 2, and 1.65% for profile 3.

The single-lane Queens Bridge carries Queens Park Road, which links Highton and Newtown. The location was originally the site of a punt, with a wooden cattle crossing being provided in 1861. Those crossing the bridge were charged a toll. The bridge collapsed in the 1870 flood, and a new wooden bridge opened in 1872. The toll ended 1877. The bridge was wrecked by the 1909 flood, but was rebuilt. The current one-lane steel bridge was opened in 1930. A water main and footpath were added on one side in 1963, and the height and deck have been modified in later years.

The Manhattan Bridge is a suspension bridge that crosses the East River in New York City, connecting Lower Manhattan at Canal Street with Downtown Brooklyn at the Flatbush Avenue Extension. The main span is long, with the suspension cables being long. The bridge's total length is . It is one of four toll-free vehicular bridges connecting Manhattan Island to Long Island; the nearby Brooklyn Bridge is just slightly further downtown, while the Queensboro and Williamsburg bridges are to the north. The bridge was designed by Leon Moisseiff, built by The Phoenix Bridge Company, and opened to traffic on December 31, 1909.
Manhattan Bridge | Introduction
Serious proposals for a bridge linking Manhattan to Long Island City were first made as early as 1838, and attempts to finance such a bridge were made by a private company beginning in 1867. Its efforts never came to fruition and the company went bankrupt in the 1890s. Successful plans finally came about in 1903 – after the creation in 1898 of Greater New York City through the amalgamation of Manhattan (New York City), Brooklyn, Queens, the Bronx and Staten Island – under the new city's Department of Bridges, led by Gustav Lindenthal, who was appointed to the new position of Commissioner of Bridges in 1902, in collaboration with Leffert L.

There was also a smaller park placed conveniently right under the Queensboro Bridge called "Baby Park". Baby Park was closed due to debris falling from the bridge during maintenance work in the late 2000s. Baby Park was replaced by a new playground for the same age range, between 40th-41st Avenues, within Queensbridge Park itself.

In 1968, the original 1926 railbridge was replaced by CN Rail with a larger, higher lift bridge. A bridgetender activates cables and counterweights to raise the span. Unless moving a train across Burrard Inlet, the lift section is always in the up position to allow ships to go underneath. The current bridge has a vertical clearance of at the main lift span fully raised (open position). The vertical lift section of the Second Narrows Railway Bridge provides clear navigation width between rubbing fenders. However, the Ironworkers Second Narrows road bridge has a vertical clearance of and the shipping channel where the maximum vertical clearance is available is wide.

The third bridge was a double-track wrought iron Pratt truss, in length and a draw of , built in 1884 by the New York, New Haven and Hartford Railroad. The current bridge, a four-track steel with Warren through truss spans, Scherzer Bascule bridge, in length and a draw of , was completed in 1906 by the American Bridge Company for the New York, New Haven and Hartford Railroad. Repairs were planned for six months starting April 25, 2015.

The Mathematical Bridge (officially named "the Wooden Bridge") crosses the River Cam and connects the older half of the college (affectionately referred to by students as the "dark side") with the newer western half (the "light side", officially known as "The Island"). It is one of the most photographed scenes in Cambridge; the typical photo being taken from the nearby Silver Street bridge. Popular fable is that the bridge was designed and built by Sir Isaac Newton without the use of nuts or bolts, and at some point in the past students or fellows attempted to take the bridge apart and put it back together.

When the construction of the Triborough Bridge was paused in 1932 due to lack of funding, the suspension span was downsized to a single deck. There are Warren trusses on each side of the span, which stiffen the deck. The center span between the two suspension towers is long, and the side spans between the suspension towers and the anchorages are each long. The total length of the bridge is , and the deck is wide. At mean high water, the towers are tall, and there is of clearance under the middle of the main span. The suspension towers were originally designed by Arthur I.

Both the 63rd Street and the 53rd Street lines merge into the Queens Boulevard Line in Queens. On June 28, 2010, the V was replaced by the M, which began using the Chrystie Street Connection to the Williamsburg Bridge. Regular M trains make all former V stops except for Second Avenue. In 2004, full Manhattan Bridge service was restored. This resulted in full B and D express service being restored from 34th Street–Herald Square to the Manhattan Bridge, where the services continued to Brooklyn. However, the terminals of the B and D were reversed from prior to the Manhattan Bridge service suspensions.

Third Avenue Bridge | Introduction
In 1905, a bridge was constructed that could accommodate for the extension of the IRT subway line into the Bronx. The 1905 Broadway Bridge was also a swinging bridge, but a second deck was added to allow for subway traffic on the upper deck, and pedestrian and highway traffic on the lower deck. The last subway train crossed the previous Broadway Bridge on December 23, 1960. Over the next two days (Christmas Eve and Christmas Day), the old bridge was removed and the already assembled new bridge floated and hoisted into position, opening to subway traffic on December 26, 1960.

There are two bridges in use in Bridgetown. The Charles Duncan O'Neal Bridge is large and modern in design, commencing from the street east of National Heroes Square, while Chamberlain Bridge is the more "decorative humpbacked bridge" built to replace the original swing bridge after the Great Hurricane with funds generated through the efforts of the then British Colonial Secretary, Joseph Chamberlain (1836–1914).

Queens College, Cambridge record that its Mathematical Bridge resembles this much grander structure also by Etheridge — unlike Walton Bridge, Etheridge's bridge there has been rebuilt twice to his design, having encountered minor wood rot, but has never collapsed. The timber structure stood approximately 33 years, that is, until 1783. A report on the condition of the bridge in 1778 suggested that decay in the wooden frame made it unsuitable for use and it was dismantled five years later.
Walton Bridge | First bridge
The outer roadway was later opened to vehicles at all times, but after a series of fatal crashes in 2013, officials decided to close the ramp during the nighttime. In March 2009, the New York City Bridge Centennial Commission sponsored events marking the centennial of the bridge's opening. The bridge was also designated as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers during the year of its centennial anniversary.
Queensboro Bridge | Since the 1980s
There have been four different bridges at this location since the 1860s, the first of which was a timber bridge was constructed between 1863 and 1867, using convict labour. The second bridge was constructed between 1896 and 1898 downstream of the existing bridge. Whilst wider and stronger, it was only intended to be a temporary structure while the old bridge was removed and replaced. However, no construction or demolition works occurred until 10 years later, with the old bridge left for pedestrians. The third bridge was a renovation of the original bridge, which had its deck replaced, new support piles added, and existing piles modified.

The myth continues that the over-ambitious engineers were unable to match Newton's feat of engineering, and had to resort to fastening the bridge by nuts and bolts. This is why nuts and bolts can be seen in the bridge today. This story is false: the bridge was built of oak in 1749 by James Essex the Younger (1722–1784) to the design of the master carpenter William Etheridge (1709–1776), 22 years after Newton died. It was later repaired in 1866 due to decay and had to be completely rebuilt in 1905. The rebuild was to the same design except made from teak, and the stepped walkway was made sloped for increased wheelchair access.
Queens' College, Cambridge | The Mathematical Bridge
This is the sixth bridge to have been built in this part of the Seekonk River. The first was a wooden bridge built by Moses Brown in 1793 called the Central Bridge, which connected the respective ends of Waterman Avenue. The same year, Brown's brother John built the first Washington Bridge at a ferry landing point one mile south, connecting India Point and Watchemoket Square. The second and third bridges were built as replacements and were destroyed in 1807 and 1815, respectively. A swing bridge was built in 1872, which was replaced by a sturdier bridge of the same type in 1895.
