The multiyear project will replace an aging east-west connection while rebuilding approaches, drainage and space for people walking and biking.

What happened
Tucson formally broke ground on the 22nd Street bridge replacement, beginning one of the region’s most consequential urban transportation projects. The bridge carries traffic across the Union Pacific rail corridor and links neighborhoods around South Tucson with employment, schools and services farther east. City plans call for a modern structure, reconstructed approaches and improvements intended to make the corridor safer for drivers, pedestrians and bicyclists.
Why it matters in Tucson
The importance of the bridge is larger than its daily traffic count. Few east-west routes cross both the railroad and the interstate cleanly in this part of Tucson, so closures and construction phasing can push traffic onto already-busy alternatives. Nearby residents and businesses should expect a long construction period, but the finished connection is designed to remove a persistent bottleneck and improve emergency access.
What to watch next
Residents should watch the city’s construction notices for detours, changing lane restrictions and access plans. The most useful measures of success will be whether the project stays within its funding plan, limits disruption to adjacent neighborhoods and delivers the promised walking, biking and drainage elements—not merely additional vehicle capacity.
