The 1,900-foot Hoover Dam bypass bridge, which is 890 feet above the river, is now open to traffic after years of planning and more than five years of construction. The four-lane bypass will shift traffic away from the two-lane U.S. 93 across Hoover Dam. It is about 1,500 feet south of the dam and crosses over Black Canyon.
After the terrorist attacks of Sept. 11, 2001, authorities banned commercial trucks from crossing Hoover Dam, forcing a 75-mile detour. The bypass is designed to provide a shorter commercial route and unclog the delays caused by security checkpoints at the dam.
The Arizona Department of Transportation says the $240 million bridge along U.S. 93 officially opened Tuesday night.
