Located on Del Mar Avenue between Norwood Place and Bencamp Street, the first phase of the Del Mar Avenue Alhambra Wash Bridge Replacement Project was completed in October 2018. Construction crews removed and replaced the west side of the bridge as well as roadway work on the south side of the bridge.
The Alhambra Wash is a regional flood control channel that is under the jurisdiction of the U.S. Army Corps of Engineers and the L.A. County Flood Control District. Due to the rainy season which runs from October to April, they do not allow any construction to take place on the wash. Due to the size of the bridge and the construction required within the Alhambra Wash channel, it was not possible to completely demolish and reconstruct the entire bridge in one dry season, which runs from April to October. Therefore, the project was designed in two distinct phases with a break during the rainy season. The second phase of the project will start on April 1, 2019, and the west side of the bridge will be opened to traffic while the east side will be closed for construction.
