The Challenge of a Lifetime…Bridging the Gap.
A quarter-mile downstream of the Hoover Dam, a 1060-foot bridge hovers 900 feet above the Colorado River. The seemingly weightless structure is North America’s longest twin-rib concrete arch.It’s also the centerpiece of a much larger project to connect Nevada and Arizona on U.S. 93, one of the Southwest’s most congested stretches of highway. Opened in 1935, shortly after the dam’s construction, the single-lane road has since been the major commercial route between Arizona, Nevada, and Utah, carrying 14,000 vehicles daily.
Construction on the nearly 2,000 foot long bridge began in late January 2005 and the completion of the entire Hoover Dam Bypass Project is expected in Late 2010. When completed, this signature bridge will span the Black Canyon, connecting the Arizona and Nevada Approach highways nearly 900-feet above the Colorado River. To complete this project, A-Core is contracted to perform all of the grinding and grooving services. This work will ensure the project is ready for traffic. The bridge is set to open on the dam’s 75th anniversary in November 2010.
