Seligman will be accessible from I-40 throughout 10-month improvement

Access to Historic Route 66 along Interstate 40 at Exit 121 will close Monday, June 11, for a $4.3 million bridge project. ADOT will replace decks on three bridges between I-40 exit 121 and the west side of Seligman. These bridges are between 40 and 50 years old, and the current decks need heavy maintenance. The second I-40 exit (Exit 123), which is about 60 miles west of Flagstaff, and route to Seligman’s east side will remain open. The project is scheduled to be completed in May 2019.

Signs on I-40 will direct travelers to exit 123, connecting to the east side of Seligman. ADOT also has produced a brochure and video explaining the project and noting that visitors will be able to reach Seligman from I-40 throughout the project.

The $4.3 million project includes:

  • Replacing the deck portions of the three bridges
  • Removing and replacing guardrails as needed
  • Reconstructing 40 feet of road on either side of the bridges
  • Repairing embankment damaged by erosion
  • Removing and replacing of the approach slabs and joints
