Every day, more than 14,000 cars and trucks travel the steep and winding approach roads to Hoover Dam. There, they cross the Colorado River, driving across the dam on a two-lane highway. Built in the early 1930s when there was much less traffic, the approach roads have now become a major bottleneck and safety hazard for travelers and those dam tourists waking on and near the dam highway. To solve this problem, the Federal Highway Administration has commissioned the Hoover Dam Bypass Project. The centerpiece of the project is a concrete arch, steel deck bridge with 1500 feet of clear span, 890 feet above the river, that will carry four lanes of traffic. It will be the largest concrete arch bridge in the US. Gee, another record.
Work on the $234 million bypass and four-lane bridge is on-budget and in line to be finished by 2010.
