Hoover Dam, and the construction of a "bridge" across the gorge Bashny.Net

Supplement (or continuing) to the theme of "the world's largest dam" (Hoover Dam, and the construction of a "bridge" across the gorge).
Sincerely, Alexander.

Hoover Dam on the motorway is 93 (Route 93), which lies in the meridional direction and connecting Arizona to the Canadian border.
Part of the highway adjacent to the dam does not match the line and the volume of the traffic. To change the situation in late 2010 was implemented commissioning of a new road bridge - Hoover Dam Bypass - through Black Canyon.

The bridge consists of two parallel reinforced concrete arches, curved upward, ending at the coast, which are based on the vertical pylons used to support the upper spans of the bridge roadway.
