The Arizona Department of Transportation advises drivers to prepare for lane restrictions on State Route 77 as it crosses over the Little Colorado River (milepost 388) into downtown Holbrook as work is scheduled to begin on a bridge rehabilitation project Wednesday, April 15.

Drivers should expect delays while the following restrictions are in place throughout the duration of the project:

• SR 77 will have lane restrictions 24/7 at the Little Colorado River Bridge. One lane will be open in each direction at all times.

• Drivers need to be prepared to slow down, expect frequent stops and plan for delays while moving through the work zone and use caution around construction personnel and equipment while the restrictions are in place.

• Traffic control will include the railroad crossing that will be controlled by on-site railroad flaggers.   

Work on the project will include milling and repairing the existing bridge deck and deck joints as well as repaving SR 77 from the north side of the bridge to Joy Nevin Avenue and 200 feet south of the bridge.

The project will require lane closures and traffic shifts into fall 2026

Work to improve a 14-mile stretch of US 160 in the Tuba City area in Northeastern Arizona is scheduled to start the week of April 6-10.

Drivers should allow extra travel time due to anticipated delays while resurfacing and other work, including guardrail and drainage system upgrades, are underway both in and east of Tuba City (mileposts 321-335).

Work in locations with more than one lane in each direction in Tuba City is scheduled from 9 a.m. to 4 p.m. Mondays through Thursdays and on Friday mornings until noon. Lane closures and traffic shifts are planned.

Along two-lane sections of US 160 east of Tuba City, flag crews and a pilot vehicle will direct traffic through work zones one direction at a time. Work is scheduled in these areas from 5 a.m. to 6 p.m. Mondays through Thursdays and on Friday mornings until noon.

ADOT is working on the $20.5 million US 160 improvement project in cooperation with the Navajo Nation and Hopi Tribe. The entire project is scheduled for completion in fall 2026.

Expect delays at times when one lane is closed for repair project

A highway repair project along westbound Interstate 40 near Williams will start the week of April 6-10 with an around-the-clock lane closure.

With westbound I-40 narrowed to one lane, drivers should plan for delays, especially during peak travel times. The project’s location is approximately 3 miles west of Williams (milepost 160). Work is scheduled for completion by late summer. Flag crews will direct traffic as needed.

Pavement damage occurred during a multi-vehicle crash and fire in March 2025. Work elements include:

• Removing temporary pavement
• Replacing damaged guardrail
• Adding new pavement
• Installing lane stripes and other pavement markings
