Hoover Dam is on Route 93 (Route 93), lying in a north-south direction and connects with the Canadian Arizona border. Part of the highway adjacent to the dam does not match the line and the volume of traffic transmitted. The road has only one lane in each direction, streamers coming down to the dam, includes several steep and narrow turns, as well as places with poor visibility, the road is subject to landslides. This must change with the expected commissioning in late 2010 road bridge - Hoover Dam Bypass - a Black Canyon. Hoover Dam Bypass - April 2009
