Drake Haglan and Associates is proud to congratulate the City of Tracy on receiving the Transportation - Bridge Category $10 - $50 Million Division Project of the Year for the 11th Street East Tracy Overhead Bridge Replacement Project. The award was issued by the American Public Works Association (APWA) Sacramento Chapter for the single-span structure with an overall bridge length of approximately 291-feet and roadway approach work of 3,400-feet supported by MSE walls to minimize the amount of right of way required and improve site aesthetics.
The existing bridge was a 1,441-foot long, 64-foot wide, multiple simple-span bridge consisting of reinforced concrete T-beams and steel girders, and crossed over three separate Union Pacific Railroad (UPRR) tracks at a skewed angle.
DHA designed a shorter highly-skewed structure in combination with retaining walls and embankment fill at the approaches to span the UPRR mainline tracks. The superstructure of the replacement bridge consists of a cast-in-place, post-tensioned concrete box girder.
The City’s goal of improved pedestrian safety was also met on this project. The new roadway section consists of two 12-foot wide through traffic lanes in each direction, 4-foot wide median, 8-foot wide shoulders which serve as Class II bicycle lanes, and 8-foot wide separated mixed use paths on each side that are protected with traffic side barriers.
Much of this project’s success can be attributed to diligent proactiveness by the DHA design team, the Hanna Group CM team, the prime contractor(s) – Teichert/MCM, and the City of Tracy – managed by Zabih Zaca.
The project was a model of collaboration from the beginning through construction completion.
Job well done City of Tracy! Congratulations!
