Temporary bridge to assist with renovation at I-10, Wilmot Road

PHOENIX ‒ For the second time in a little more than a year, Arizona Department of Transportation crews will use a temporary bridge while renovating an Interstate 10 overpass in the Tucson area so work can be completed without closing freeway lanes.

Eastbound traffic this week began using a two-lane temporary bridge over Wilmot Road in southeast Tucson in the median between the eastbound and westbound lanes of I-10. There is no impact on westbound traffic.

Work on the eastbound bridge is expected to be completed in August, at which time the process will be reversed with westbound traffic moving to the temporary structure and eastbound traffic returning to its original lanes.

The $4 million project will replace the bridge decks in both directions and extend the life of the bridge. Work is expected to be completed by December.

This is the second time ADOT has used a temporary bridge to make bridge improvements without closing freeway lanes. In 2017, a two-lane temporary bridge was used while renovating overpasses at Craycroft Road.

“Using a temporary bridge allows us to extend the life of this bridge while causing the least possible delay for Pima County drivers,” said Rod Lane, district engineer for ADOT’s South Central District.
