Flagstaff Traffic Alert: Lane closures planned on Beulah Boulevard under Interstate 40

Posted on by

FLAGSTAFF – Arizona Department of Transportation crews are scheduled to set lane restrictions on Beulah Boulevard under the I-40 bridge overpass in Flagstaff. Drivers are advised to allow extra travel time as crews will have lane closures in both directions from 8 p.m. Thursday, April 12, to 5 a.m. Friday, April 13. One lane in each direction will remain open at all times. Additionally, lane widths will be restricted to 11 feet throughout the construction project.

These lane closures and width restrictions are necessary for crews to begin bridge deck replacement and repair work at the I-17 and I-40 interchange in Flagstaff. This project will replace three bridge decks and approach slabs, increase the bridge cross slopes and retrofit one bridge deck with an overlay. The project will also include guardrail and paving work.

Construction began in February 2018 and the majority of the work is scheduled to be complete by the end of the year.

ADOT is scheduled to host informational sessions for the public from 5:30 to 7 p.m. on April 9, May 8, June 12 and July 10. These open houses will be at ADOT’s facility at 1901 S. Milton Road in Flagstaff. Project team members will be available to provide information and answer questions on the construction schedule and traffic impacts.

What to Expect:

  • Construction seven days a week with both day and night work, according to project phasing
  • Overnight, one-direction closures on Beulah Boulevard beneath I-40
  • Rolling night closures of I-17, according to phasing
  • Ramp closures
  • The southbound I-17 to eastbound I-40 ramp is scheduled to be closed in two-week increments at the end of June, end of July and end of October
