The Mike O'Callaghan – Pat Tillman Memorial Bridge (Known as the Hoover Dam Bypass during planning and early constuction) provides a bridge connecting roads for a new route across the Colorado River for U.S. Route 93. The project links the U.S. states of Nevada and Arizona by spanning the Colorado River 1,600 ft (490 m) downstream from the Hoover Dam. The entire project is expected to be completed by September 2010. Its cost has been estimated to be about $240 million. Once the bypass is completed, the existing roadway across Hoover Dam will be closed to through traffic.
The bridge and the new sections of U.S. Highway 93 will be four lanes wide. Total length of the bridge is 1,900 feet (579 m) with a 1,080 ft (330 m) main span. The roadway will be 840 ft (260 m) above the river. When completed, it will be the first so-called concrete-steel composite arch bridge built in the United States. The composite design, using concrete for the arch and columns with steel construction for the roadway deck, was selected for schedule and cost control while still being aesthetically compatible with Hoover Dam. Pedestrians will be able to park and walk across the bridge for views of the Hoover Dam, but the dam will not be visible to most drivers on the bridge. Google Earth Ready.
