The Nevada Department of Transportation reported on November 7 that construction is now halfway done on the state’s second longest bridge: a 2,635-foot-long highway “flyover” structure that will connect northbound U.S. Highway 95 to the westbound 215 Beltway in northwest Las Vegas.

That flyover – which provides direct freeway-to-freeway connections while still maintaining highway travel speeds for greater efficiency and safety – is part of the larger $73 million Centennial Bowl interchange project that broke ground in January, the agency noted in a statement.

The 75-foot-tall by 39-foot-wide bridge is a box girder type structure built from cast-in-place concrete that equals the length of seven football fields laid end-to-end, providing one travel lane in each direction linking north-to-west freeway traffic. The bridge uses 18,900 cubic yards of concrete, or enough to fill six Olympic-sized swimming pools, delivered by 1,500 cement mixer truck trips.
