​7th Street Bridge Reopens

​After an expedited six-month repair and reconstruction project, the City of Phoenix Street Transportation Department reopened the 7th Street bridge on Saturday, August 28, 2021.

A gas utility line fire on February 28, 2021 caused significant damage to the bridge, which spans the Salt River and Rio Salado Habitat Restoration Area. Approximately 40 percent of the structure was damaged and needed to be rebuilt.​

Access to city trails under the bridge also was restricted. A project to refurbish the trails and revegetate the area was completed in fall 2021.​


Interesting Project Facts

  • Crews worked to install 20 new rebar-reinforced concrete girders, each weighing 191,000 pounds

  • Repouring of the driving surface required 705 tons of concrete

  • The bridge deck was poured on August 6, requiring a convoy of more than 80 concrete trucks

  • Handrails along the entire bridge were replaced and updated to meet current safety standards

  • The new portion of the bridge has a 75-year lifespan​​​
