Westbound I-40 pavement work near Williams starts week of April 6

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

FLAGSTAFF - 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, according to the Arizona Department of Transportation.

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
