SR 89A

PHOENIX – A federal project improving safety and traffic flow along State Route 89A between the Flagstaff area and Oak Creek Canyon requires daytime restrictions on weekdays and, starting later this month, overnight closures.

PHOENIX – In partnership with Sedona, the U.S. Forest Service and Coconino County, the Arizona Department of Transportation will add protective fencing over the next few weeks to Midgley Bridge along State Route 89A.

The city of Sedona sought ADOT’s help after four people committed suicide from the bridge in 2015. After working with a nonprofit organization to add signs carrying the number of a suicide-prevention hotline, ADOT worked with area partners to design fencing for the bridge, located a mile and a half north of Sedona. 

It’s been a while since we last checked in up north on the I-17/JW Powell traffic interchange improvement project.

It’s not all roads and bridges, here at ADOT. Sometimes the projects we take on include stabilizing the areas near a highway.

State Route 89A in the Oak Creek Canyon switchbacks (mileposts 387-390) was fully reopened this afternoon after crews repaired a sinkhole that had been discovered in the northbound lane on Saturday.

Drivers traveling between Sedona and Flagstaff received welcome news when ADOT opened the "switchbacks" section of State Route 89A well ahead of schedule.

In order to provide a safer flow for traffic, ADOT will realign SR 89A and reconstruct the intersection of southbound I-17 and JW Powell Boulevard three miles south of Flagstaff.

ADOT will soon begin a project that will restore the pavement along a 3.5-mile segment of SR 89A through the Oak Creek Canyon switchbacks.

There’s a realignment and intersection improvement project in the works near Flagstaff that, when complete, will help eliminate some major backups in the area.
