I-40: Winona Bridge Rehabilitation


The Arizona Department of Transportation has initiated a project on Interstate 40 about 16 miles east of Flagstaff.

The work will rehabilitate the Winona bridge (milepost 211), which includes removing and replacing the existing bridge deck (the top surface of the bridge that vehicles drive on), guardrail, cattle guards and steel support beams on the bridge.

About the Project

  • The 277-foot steel girder bridge was originally constructed in 1967.
  • Construction will be phased so single-lane traffic can be maintained on Townsend-Winona Road, except during limited times during the project when detours will be established.

What to Expect During Construction

  • Intermittent, overnight closures of I-40
    • Drivers on I-40 will use the off- and on-ramps at the Townsend-Winona Road interchange to exit and re-enter the highway.
  • Townsend-Winona Road will be narrowed to one lane only of alternating north- and southbound travel during the project. This will enable crews to work on half of the bridge at a time. The interchange will be controlled by temporary traffic signals.

Project Schedule

  • Spring 2020 - Spring 2021

Schedule subject to change based on weather or other unforeseen factors.
