Southbound I-17 closed overnight at I-40 interchange August 16-24

I-40 reduced to one lane in each direction as bridge work continues

Southbound Interstate 17 will close overnights at the I-17/I-40 interchange in Flagstaff next week while crews continue to remove the I-40 bridge decks.

Beginning Thursday, August 16, southbound I-17 will close where the highway passes under Interstate 40. This section will close nightly from 8 p.m. to 5 a.m. through Friday, August 24. Drivers heading south out of Flagstaff will need to take I-40 west to the Flagstaff Ranch Road exit, then use I-40 eastbound to the exit for southbound I-17.

Also, I-40 has been narrowed to one lane in each direction through the interchange.

The $10 million project includes replacing the I-40 bridge decks in each direction over Beulah Boulevard, immediately west of I-17, as well as the westbound bridge deck over I-17. The eastbound I-40 bridge over I-17 will get a new concrete surface.

The project will also increase the cross slope of the roadway over the renovated bridges, helping drain water off of the road surface. It also includes guardrail and paving work.
