July/August 2009 Colorado River Bridge Status Update

Colorado River Bridge Project Nearing Completion

The joint venture contractor building the River Bridge, Obayashi Corporation and PSM Construction USA, Inc., has completed the connection of the 1,060 foot twin-rib concrete arch. Completion of the arch represents an enormous engineering achievement. Spandrel columns on the arch were completed in December 2009. These columns will now support the superstructure of the bridge. Remaining work includes placement of the steel tub girders sequential construction of the cast in place concrete deck, pedestrian and barrier rails, final finishing and site decommissioning. The final sections of the arch were connected on August 10, 2009. Removal of the supporting cable system was completed on August 27th, and the arch now self supporting and free standing.

Upcoming work will include setting the precast columns, erecting the steel girders, and casting of the roadway deck and barriers. (Please see the July/August Project Status Update, in the above box, for more detail on this process.) The bridge remains on schedule for completion by September 2010. Opening of the bypass is on track for November 2010.

Interim Paving Contract Complete

The fourth phase of the Hoover Dam Bypass project is complete. The interim surfacing project was awarded to Las Vegas Paving Corporation in December 2007 was completed in June 2008. The project included asphalt paving and guardrail on approximately 75% of the approach project length. Completion of the project minimizes the amount of remaining work to be done after the River Bridge is completed. The final project to open the bypass will include the short sections of remaining roadway tie-ins to the River Bridge and U.S. 93, as well as signing, striping, barrier, and pedestrian facilities on the entire bypass.

Final Contract Awarded

The Federal Highway Administration (FHWA) has awarded a $7 million contract to Frehner Construction Company, Inc. of North Las Vegas, Nevada to complete the final roadway elements that will allow traffic onto the Hoover Dam Bypass.

This work will complete signing, striping, median barrier, lighting, paving, and roadway tie-ins at U.S. 93. Additional work will include the paving and parking area improvements for the visitor and pedestrian plaza.
