No access to eastbound Interstate 40 from A-1 Mountain this week and early next

Northern Arizona drivers who access eastbound I-40 at A-1 Mountain (milepost 190) will use an alternate route this week and early next week because of guardrail replacement work. The Arizona Department of Transportation advises drivers to allow extra travel time as the nearest interchange — at Bellemont — is five miles to the west.

The A-1 Mountain on-ramp to eastbound I-40 is closed to 6 p.m. today and again from 6 a.m. to 6 p.m. on Monday, Oct. 16. Drivers will use westbound I-40 to Bellemont (milepost 185) and turn around at the Bellemont traffic interchange to access eastbound I-40.

Crews are scheduled to replace the guardrail at the A-1 Mountain interchange in conjunction with the ongoing project to rehabilitate 12 miles of pavement along I-40 between mileposts 179 and 191, approximately four miles west of Flagstaff. Learn more at azdot.gov/I40Paving.
