The Bureau of Reclamation had a major arterial clog to solve when it imagined a bridge over the Colorado River near Hoover Dam. US 93 is the major artery between Nevada and Arizona and it was often clogged with vehicle and pedestrian traffic as people slowed or stopped to view the Dam.
The Mike O'Callaghan-Pat Tillman Memorial Bridge was the answer to the problem. Soaring almost 900 feet above Black Canyon the bridge contains a magnificient 1,060 twin rib concrete arch. None of its majesty is apparent when you drive over the bridge. You can't even see Hoover Dam from the bridge.
However, from the viewing sites along Hoover Dam, the new bridge's graceful arch links the canyon walls and serves as a big bypass.
