When was the Michigan International Speedway built?
Michigan International Speedway
Groundbreaking took place on September 28, 1967. Over 2.5million cubic yards (1.9×10^6m3) of dirt were moved to form the D-shaped oval. The track opened in 1968 with a total capacity of 25,000seats. The track was originally built and owned by Lawrence H. LoPatin, a Detroit-area land developer who built the speedway at an estimated cost of $4–6million.[3] Financing was arranged by Thomas W Itin. Its first race took place on Sunday, October 13, 1968, with the running of the USAC 250 mile Championship Car Race won by Ronnie Bucknum.
History of Indiana
The Indianapolis Motor Speedway complex was built in 1909, inaugurating a new era in history. Most Indiana cities within 200 miles of Detroit became part of the giant automobile industry after 1910. The Indianapolis speedway was a venue for auto companies to show off their products. The Indianapolis 500 quickly became the standard in auto racing as European and American companies competed to build the fastest automobile and win at the track. Industrial and technological industries thrived during this era, George Kingston developed an early carburetor in 1902; in 1912, Elwood Haynes received a patent for stainless steel.
