Hoover Dam, lying on the border between Nevada and Arizona, was the biggest hydro-electric power plant and the largest concrete structure of the world, when it was built on 1936. It was surpassed later on by several dams across the world.
Hoover Dam Bypass Project is simply a bridge on the Colorado River, which will span the Black Canyon and connect two sides of the dam. When completed in late 2010, it will be the largest concrete-arch bridge in the western hemisphere. Bridge will be 580 meters long, and 275 meters above the river.
The bridge will include a pedestrian walkway (hence, here comes a new bungee jumping spot).
