Nightly closures of I-17 in northern Arizona to begin Tuesday
PHOENIX – Bridge improvement work beginning Tuesday will force a major highway interchange in northern Arizona to be closed nightly for at least two weeks, according to the Arizona Department of Transportation.
The northbound lanes of Interstate 17 where the highway passes under Interstate 40 in Flagstaff will be closed from 8 p.m. to 5 a.m. through June 2 to allow crews to set up support structures to replace the bridge decks on I-40.
All northbound I-17 traffic heading into Flagstaff will be forced to exit to I-40 east, using Butler Avenue to enter the westbound lanes of I-40 before taking Milton Road into town.
The southbound lanes of I-17 will be closed in the same section beginning on Monday, June 4 through Saturday, June 8.
Vehicles traveling south out of Flagstaff will have to take I-40 west to the Flagstaff Ranch Road exit before wrapping back around I-40 east to the I-17 south exit.
Along with replacing the I-40 bridge decks in each direction over Beulah Boulevard, the $10 million project will also replace the westbound bridge deck over I-17.
Additionally, the eastbound I-40 bridge over I-17 will receive a new concrete surface.
The cross slope of the roadway over the renovated bridges will also be increased in order to help drain water off of the road surface.
