Updated: Schedule for I-17 overnight closures in Flagstaff
Traffic to detour on ramps, crews to set girders for new bridge
FLAGSTAFF – Overnight closures of Interstate 17 at J.W. Powell Boulevard near Pulliam Airport in Flagstaff start Monday night (June 17) and will continue on a Monday through Thursday schedule the next two weeks. The schedule has been updated. Crews will set girders and continue other work on a new, improved bridge as part of an Arizona Department of Transportation project at the J.W. Powell Boulevard interchange.
Traffic will detour along the off- and on-ramps at the interchange while the following closures are in place:
- Northbound I-17 closed at J.W. Powell Boulevard from 7 p.m. to 5 a.m. Monday and Tuesday nights (June 17-18 and June 24-25).
- Southbound I-17 closed at J.W. Powell Boulevard from 7 p.m. to 5 a.m. Wednesday and Thursday nights (June 19-20 and June 26-27).
Drivers should allow extra travel time while the overnight I-17 closures are in place. The placement of the bridge girders marks the latest milestone for the $8.2 million project that is adding the new structure to carry J.W. Powell Boulevard over the highway.
Traffic is continuing to use the existing bridge at the interchange. The interchange improvement project is scheduled for completion by late this year. Drivers should slow down and stay alert for highway workers and equipment in all work zones.
