Corps awards contract for Nogales bridge design

Published April 9, 2013

NOGALES, Ariz. — The U.S. Army Corps of Engineers Los Angeles District awarded a contract for approximately $476,000 on March 29 to redesign the Old Tucson Road bridge over Nogales Wash.

When constructed, the bridge project will restore access across Nogales Wash, provide capacity in the channel for the existing water flow of 4,000 cubic feet per second, and protect the existing 30-inch sewer line in place.

The redesign is for a concrete I-girder bridge, widely used for short to medium spans and for its reduced cost benefits.

"This design is far different than previous designs - most significantly, we will see far less in-channel disturbance to construct the bridge structure," said Drew Savage, Corps project manager. "Conversely, we will not be constructing any flood control improvements, with the exception of channel side-slope hardening that will principally protect the bridge structure."

The redesign contract will finalize a design for the bridge over the wash, so the Corps can advertise the actual construction contact at the end of July.  Then, the Corps will award the contract for construction in September.
