Bypass Now Open!
The Federal Highway Administration,
in conjunction with the Arizona Department of Transportation (ADOT)
and the Nevada Department of Transportation (NDOT), officially
opened the new segment of US 93, formally known as the Hoover Dam
Bypass. Traffic began flowing on Tuesday night, October 19, 2010.
Colorado River Bridge Project
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
2010. Opening of the bypass is on track for November 2010.
Paving Contract Complete
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
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
