US 160 Dennehotso - MP 440 Pavement Rehabilitation

Overview

Project Cost: $19.7 million

The Arizona Department of Transportation, in partnership with the Navajo Nation, is currently working on a pavement rehabilitation 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 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.
