GAF XPro Levitated Mass 04
That right there is a 340-ton boulder on a 196-wheeled truck rollin' down the street.  

Levitated Mass is a 2012 large-scale sculpture by Michael Heizer on the campus of the Los Angeles County Museum of Art.  

Heizer first conceived of the work in 1968, and attempted its construction using a 120-ton boulder in 1969. This attempt was abandoned, however, when the boom of the crane being used to lift the boulder broke. In December 2006, Heizer discovered a new, larger rock at Stone Valley Quarry in Jurupa Valley.  

The rock was loaded onto a 295-foot long, 196-wheeled transporter custom-built by Emmert International. Because of the transporter's size and needs, the boulder could only be moved at night at a maximum speed of about seven miles per hour. 

Numerous trees were cut down, cars towed and traffic lights temporarily removed in order to facilitate the transporter's movement. The trip took 11 days, with large crowds gathering to see the boulder both in motion and while parked during the day. Spontaneous block parties and at least one marriage proposal took place at the transporter's various resting places.
