|PHOENIX – Interstate 17 will close overnights at the I-17/I-40 interchange in Flagstaff next week while crews remove the westbound I-40 bridge deck.
Beginning Sunday, June 17, southbound I-17 will close where the highway passes under Interstate 40. The same section will close nightly from 8 p.m. to 5 a.m. through Tuesday, June 19. Drivers heading south out of Flagstaff will need to take I-40 west to the Flagstaff Ranch Road exit and come around to I-40 eastbound to take the exit for I-17 south.
On Wednesday, June 20, northbound I-17 will close under I-40 nightly from 8 p.m. to 5 a.m. through Friday, June 22. Traffic heading north on I-17 into Flagstaff will need to exit on to I-40 east and use the Butler Avenue exit to come around to I-40 westbound and take the Milton Road exit into town.
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.
