Interstate 40: East Seligman Bridge Decks Replacement

Interstate 40: East Seligman Bridge Decks Replacement



Project is on a hiatus, and will resume in summer 2024



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

Work is taking place at the I-40 East Seligman Traffic Interchange (TI) overpass, located between mileposts 122 and 125. 

This project is on a hiatus during the winter months and will resume in spring 2024.

The $6.1 million 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.
