Interstate 10: West Willcox traffic interchange bridge project


Willcox Project Map

The Arizona Department of Transportation is completing a project to replace the deck on the bridge over Interstate 10 on the west end of Willcox.

Other elements of the project include:

  • Barrier replacement
  • Replacing pavement adjacent to the bridge
  • Guardrail upgrades
  • New signing and striping

Preliminary work began in late March 2021, and project completion scheduled for autumn 2021.

The project is scheduled to be completed in three phases:

  • Phase 1 tentatively from late March to mid-April - mobilization and construction of a temporary traffic lane to facilitate the movement of westbound I-10 traffic during scheduled I-10 closures.
  • Phase 2 tentatively from mid-April to late summer - removal and replacement of the bridge deck
  • Phase 3 tentatively from late summer to early autumn - guardrail and pavement work and cleanup

Traffic Impacts

The bridge over I-10 and the eastbound I-10 on-ramp will remain closed to all traffic for the duration of the project. Other exit and entrance ramps will remain open. However, vehicles will not be able to cross I-10. 

Some work in phase 2 will require weekend closures of I-10 from 6 p.m. Fridays to 6 a.m. Mondays. At that time, I-10 traffic will be diverted onto the exit ramps and back to I-10 using the entrance ramps.
