US 191 Chinle - Black Mountain Wash Shoulder Widening

Overview

Project Cost: $17,066,000

The Arizona Department of Transportation will initiate a shoulder widening project on US 191in northeastern Arizona. The project boundary is roughly between Chinle and about nine miles south of Many Farms on the Navajo Nation (milepost 448 – 460). The project is within ADOT’s existing right of way.

Project Elements

The purpose of the project is to improve safety by widening the shoulder on both sides of the roadway to reduce run-off road and rollover crashes.

The work includes, but is not limited to:

• Installing rumble strips on centerline and shoulders
• Installing pavement markings
• Installing traffic delineators, as required
• Replacing signs and pavement markers, as necessary

What to Expect During Construction

Construction will result in traffic restrictions for the traveling public. The roadway within the project boundary will be reduced to one lane of alternating north- and southbound travel through the construction zone. A pilot car will lead traffic through the work zone during construction.

ADOT will post additional information on traffic restrictions and closures as it becomes available. To receive traffic alerts and other updates by email, please subscribe here.

You can also stay informed of real-time, project-related traffic restrictions by visiting az511.gov or call 511, except while driving.

Schedules are subject to change because of weather or other unforeseen factors. Remember to slow down and use caution around construction workers and equipment. 

Traffic Alerts

US 191 narrowed to one lane only of alternating travel between the communities of Chinle and Many Farms through November

Drivers should expect delays

The Arizona Department of Transportation advises drivers to plan for the following travel restriction on US 191 between Chinle and Many Farms (mileposts 448-460) in far northeastern Arizona:

• US 191 will be reduced to one lane only with alternating north- and southbound travel daily from 6 a.m. to 5 p.m. Mondays through Fridays beginning Sept. 6, through November.
• Flaggers and a pilot car will direct traffic through the work zone.
• The speed limit will be reduced in the work zone.
• Drivers should be prepared to stop when approaching the work zone.
• The restrictions will be lifted each day after work hours and during the weekend.

Crews need the lane closures to safely complete shoulder widening improvements, turnout improvements, and corrugated metal pipe extensions.  

Closures and restrictions will be in place until winter shutdown, then resume in the spring of 2023 for the duration of the 12-mile shoulder widening project.
