US 160 Dennehotso - MP 440 Pavement Rehabilitation

Overview

Project Cost: $19.7 million

The Arizona Department of Transportation, in partnership with the Navajo Nation, has initiated a pavement project along US 160 in far northeast Arizona. The 24-mile-long project is roughly between the communities of Dennehotso and Mexican Water. 

Construction is expected to begin in March 2025 and be completed by the end of the year.

Project Map

Project Elements

• Remove and replace the top-pavement surface along US 160 in both directions between mileposts 416 and 440.
• Remove existing bridge rail on the Walker Creek Bridge near the Mexican Water Trading Post (milepost 435) and replace it with concrete barrier.
• Replace guardrail, install centerline rumble strips, build up shoulders, replace cattle guards and pave turnouts within ADOT right-of-way in the project area.
• Complete paving with a chip seal treatment and new permanent pavement markings.

What to Expect During Construction

US 160 will be reduced to one lane only in segments with alternating east- and westbound travel during construction. Vehicles will be directed through the work zone by flaggers and a pilot car. Work will take place Mondays through Thursdays during daylight hours, and Fridays from 6 a.m. to noon. No work is planned on weekends or holidays. A 12-foot vehicle-width restriction will be in place during paving operations.

Drivers should plan for extra travel time and watch for construction workers and equipment while traveling through the area.
