The Arizona Department of Transportation announced on Mar. 25 that highway improvement projects across Northern Arizona will resume or begin as spring weather arrives.
These projects are important for improving safety and maintaining infrastructure in the region. Drivers are advised to use caution and plan for possible lane restrictions while work is underway.
Several key projects are scheduled. The Interstate 17 wildlife crossing south of Flagstaff, which aims to reduce vehicle collisions with animals, will see construction resume in April with completion expected this fall. The State Route 87 improvement project in Payson will focus on sidewalk and ramp upgrades before resurfacing five miles of roadway by May, with mostly overnight lane restrictions planned through late fall. In Oak Creek Canyon, the State Route 89A guardrail project will start in April to replace barriers along switchbacks north of Sedona; drivers may encounter daytime or around-the-clock lane closures.
Pavement improvements are also resuming on Interstate 40 near Kingman and west of Winslow, as well as a new preservation project from US 93 east to Silver Springs Road starting in April. Work on State Route 64 north of I-40 in Williams involves resurfacing nineteen miles and adding turn lanes, with completion set for fall 2027. A fourteen-mile pavement improvement along US 160 near Tuba City is slated to begin soon and finish by this fall.
