WILLCOX – 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 is scheduled to begin March 23, with completion scheduled for autumn 2021. The bridge is scheduled to close starting Monday, April 5.

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

During phase 1, minor traffic impacts are anticipated with flaggers and short delays when crews are working near traffic.

Starting April 5 and extending through phases 2 and 3, the bridge over I-10 will close to all traffic. 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 8 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.
