The American Public Works Association has recognized the Hoover Dam bypass as one of its projects of the year.
The bypass, including the Mike O’Callaghan-Pat Tillman Memorial Bridge, will be recognized as the project of the year in the transportation category for the national association at its conference in Denver in three weeks.
The association will also recognize projects in the categories of disaster/emergency construction, environment, historical restoration and structures.
The bypass bridge is the longest arched concrete bridge in the Western Hemisphere and includes the world’s tallest precast concrete columns. The bridge connects Nevada and Arizona, providing a new route for U.S. 93, which previously was restricted to going over the dam.
Work on the $240 million bypass project began in 2003 and ended in October.
The project was built under the direction of the Federal Highway Administration with contractors Obayashi Corporation and PSM Construction USA and consultants HDR Engineering, T.Y. Lin International and Jacobs Engineering Group.
