Veteran's Memorial Overpass

This award-winning overpass improvement project replaced a deteriorating structure built in 1956 as part of a defense highway. The Palo Verde Bridge, also known as Veterans Memorial Overpass, was reconstructed from 44th Street to Alvernon Way, providing four new through-traffic lanes and a shared-use pathway on one side.

This project consisted of four bridge structures; three over the Tucson Diversion Channel plus one large four-lane bridge over the Union Pacific Railroad (UPRR) tracks.

The incorporation of value engineering (VE) contract changes was an example of an innovative approach to completing this long-awaited project. VE changes, such as arch culverts and MSE walls, dramatically accelerated the project schedule while reducing project construction costs by $1 million. We split the savings evenly with the Pima County Department of Transportation.
