Phoenix, AZ – Drivers traveling through southern Arizona should prepare for long-term delays as major construction begins this week along Interstate 10 near Vail, according to the Arizona Department of Transportation (ADOT).
According to ADOT, I-10 will be reduced to one lane in each direction between State Routes 83 and 90, covering mileposts 292–293, as crews launch a multi-year rehabilitation project. The work includes repaving the highway, installing new guardrails, upgrading pavement markers, and rehabilitating four railroad bridges that cross the interstate.
The project is expected to significantly affect travel for commuters heading between Tucson, Benson, and surrounding Pima County communities. ADOT says motorists should expect the left lanes in both directions to remain closed 24/7 until the project wraps up in late spring 2026. Crews will be active daily between 6 a.m. and 7 p.m., which may create additional delays during peak travel hours.
A 16-foot vehicle width restriction is now in place through the work zone, and the speed limit has been reduced to 55 mph. ADOT warns that drivers should plan for slowdowns, especially during morning and evening traffic, and encourages travelers to allow extra time when passing through the construction area.
The agency has also released a project map showing the affected section of I-10, including the bridge locations and narrowed lanes near Empiria Road.
Motorists can stay updated on closures and progress through ADOT’s real-time travel alerts and statewide 511 system.
