When the great Hooverdam was opened in 1936 Clark County, the county in which the city of Las Vegas is located, was hardly inhabited. Route US93, which was led over the dam could easily manage the traffic between Nevada and Arizona. Las Vegas made its ongoing growth spurt, the traffic load increased. When access to the dam was limited as a result of 9/11 the dam became more and more a bottle neck.
Plans for an alternate route had existed since the 1960s. It took until 2003 till the ground was broken for the construction. An impressive bridge was built slightly south of the Dam, 579 meters (1900 ft) long, and 274 meters (900 ft) above the Colorado River. It is currently the second highest bridge in the US, containing the widest concrete arch in the western hemisphere. A real marvel of civil engineering.
When I last visited the Hoover Dam, in 2012 (see here) I did not realize that the bridge was about to be opened at that time. It would take just three weeks. But today I could finally use it. Route US93 is now routed over the bridge. The old US93 still leads to the dam but does not provide through traffic access anymore. One may not stop on the bridge, but, there is an excellent way to enjoy the views, from a pedestrian path at the North side of the bridge. Starting at a parking lo that was in use for the construction. A real thrill so high over the river and with such great views on the dam.
