Downtown Tucson’s Diamondback Bridge to Undergo Major Repairs

Beginning Monday, March 10, the Diamondback Snake Bridge in Downtown Tucson will enter a repair phase that may disrupt local traffic patterns.

City officials have announced plans for sandblasting, fixing cracked concrete, and repainting the bridge’s underside. These repairs are expected to enhance safety and longevity.

The 240-foot bridge spans Broadway, connecting Maclovio Barraza Parkway/Barraza Aviation Highway to Euclid Avenue. While two lanes of traffic will remain open in each direction, the bridge itself will be closed to both pedestrians and cyclists throughout the project, which is projected to complete by mid-June.

Designed by local artist Simon Donovan in 2002 and constructed by Hunter Contracting, the bridge is noted for its distinctive diamondback rattlesnake design and has received accolades, including the American Public Works Association’s National Project of the Year award in 2003.

During the repairs, pedestrians wishing to cross the bridge will be redirected to Euclid Avenue. Additionally, sidewalk access beneath the bridge will be limited as crews undertake their work.

Construction crews will operate Monday through Thursday from 6:30 a.m. to 5 p.m., with traffic controls set up 24/7. The timeline for completion may adjust due to weather or other unforeseen events, and electronic message boards will inform motorists about the construction.

The city advises all motorists and pedestrians to heed traffic control signs and remain vigilant for construction personnel in the vicinity.
