Corps awards Vandenberg bridge replacement contract

Published Sept. 29, 2015

LOS ANGELES -- The U.S. Army Corps of Engineers Los Angeles District awarded a $23.92 million contract to Granite Construction Company, a Watsonville, California-based firm, to construct a replacement bridge over the Santa Ynez River at Vandenberg Air Force Base, California, Sept. 24. 

The contract calls for the construction of an approximately 650 feet long by 44 feet wide concrete bridge and approximately 2,400 feet of roadway approaches. Work is anticipated to include construction of a temporary access road and trestle, and removal of the existing bridge.

The 13th Street Bridge was constructed in 1970 and serves as the only on‐base transport route and vehicle link between the north and south portions of Vandenberg. In 1981, due to structural deficiencies and inadequacy of the foundation to accommodate standard highway loading, the bridge was retrofitted. An engineering evaluation in 2002 found that the bridge was still unsafe for normal highway loads and at significant risk of collapse during a 5‐year storm event. Temporary repairs were completed in 2003 and 2005.

Work is scheduled to begin this fall and be complete in late 2017.
