Interstate 40: East Seligman Bridge Decks Replacement

The Arizona Department of Transportation in conjunction with the Federal Highway Administration is planning to reconstruct and replace the east- and westbound bridge decks on Interstate 40 at exit 123 near Seligman in Yavapai County.

Work will occur at the I-40 East Seligman Traffic Interchange (TI) overpass, and the project area will be located between milepost 122 and 125. 

Construction is scheduled to begin in the spring of 2022 with a shutdown during the 2022-23 winter season, and final project completion is anticipated in fall of 2023. The project is needed to replace the damaged elements of the bridges, perform other upgrades to increase the lifespan of the bridges and includes the following:

  • Removing and replacing the deck portions of the two bridges
  • Removing and replacing approach and departure slabs
  • Removing and replacing guardrails as needed
  • Removing and replacing embankment curb as needed

During construction, I-40 will be reduced to one lane only in each direction, and crossovers will be constructed to shift traffic to one side of the interstate while work on the bridge in the other direction takes place.

Access to all adjacent properties will be maintained during daytime hours. At times there will be night closures on B40 at I-40 for demolition, installing and removing falsework, and concrete pours. All on and off ramps will remain open.
