Hoover Dam Bypass Bridge (August 2010)

The Hoover Dam Bypass Bridge provides a bridge connecting roads for a new route across the Colorado River for U.S. Route 93. The project links the U.S. states of Nevada and Arizona by spanning the Colorado River 1,600 ft (490 m) downstream from the Hoover Dam. The bridge is expected to be open to traffic in November 2010. Total cost has been estimated to be about $240 million. Once the bypass is completed, the existing roadway across Hoover Dam will be closed to through traffic.

***Milestones***
July 1998 Planning and environmental work is completed and the environmental impact statement is issued.

July 2001 Design of the preferred alternative begins.

2003 Work begins on the approaches in both states.

October 2004 The construction contract for the arch bridge is awarded.

May 2006 The bridge's construction was in its beginning stages when a permit problem between Clark County and subcontractor Casino Ready Mix arose over the operation of a concrete batch plant for the project.

September 2006 High winds cause a cableway failure, resulting in a two year delay.

April 2007 The bypass and the bridge were under construction and large cranes were visible near the river when looking from Hoover Dam.

March 2008 The approach spans were completed, consisting of seven pairs of concrete columns—five on the Nevada side and two on the Arizona side.[4] The spans will act as the springboard for the remaining segments, with two more cable towers to be built on them to complete construction of the bridge.

November 2008 Sherman Jones dies in a construction accident.

May 2009 The concrete arch 50% completed, and on track for closure in the third quarter of 2009. Most of the arch segments have been cast in place using a temporary form traveler system. Other completed work includes the precast segments for the bridge columns which will support the roadway on the arch.

August 2009 The twin arch spans were closed with the casting of the center segments. With the removal of the temporary cable stays, the arch is self supporting.

December 2009 All eight of the vertical piers on the arch were set and capped. At the end of the month the first two of thirty six, 50 ton steel girders were set into place.

April 2010 By the middle of the month all of the girders were set in place and for the first time construction crews could walk from Arizona across to Nevada. Shortly thereafter, the pouring of the road deck begins.
