Welcome to the Hoover Dam Bypass Website

Construction of the Colorado River Bridge is advancing with construction of the 1,060 foot twin-rib concrete arch.  The Colorado River Bridge is the central portion of the Hoover Dam Bypass Project. 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 June 2010.  When completed, this signature bridge will span the Black Canyon (about 1,600 feet south of the Hoover Dam), connecting the Arizona and Nevada Approach highways nearly 900-feet above the Colorado River. Use the web cam icon to the left, to see real-time images of construction on the bridge!  Visit the What's New and Construction Activities pages for more details on how this project is advancing.

United States Highway 93 (U.S. 93) has been designated a North American Free Trade Agreement (NAFTA) route. The increasing congestion caused by the switchbacks leading to the Hoover Dam site and the restrictions at the dam crossing have led to the development of the Hoover Bypass Project. The Hoover Dam Bypass Project is a 3.5-mile corridor beginning at approximately milepost 2.2 in Clark County, Nevada and crossing the Colorado River approximately 1,500 feet downstream of the Hoover Dam, then terminating in Mohave County, Arizona near milepost 1.7 on U.S. 93.

A Project Management Team (PMT) was developed to oversee the design and construction of the project. The PMT has representation from each of the major project stakeholders including the Federal Highway Administration (FHWA), the States of Arizona and Nevada, the Bureau of Reclamation (BOR), the Western Area Power Administration (WAPA) and the National Park Service (NPS). Central Federal Lands Highway Division (CFLHD) will act in the lead management role for all elements of project procurement, design and construction.

CFLHD awarded a contract to HDR Engineering, Inc. to provide design and construction support services for the Hoover Bypass Project. An integrated team of professionals from HDR Engineering, T.Y. Lin International, Sverdrup Civil, Inc. and several supporting subconsultants make up the consultant team, collectively known as Hoover Support Team.
