The Arizona Department of Transportation advises drivers to plan for the following westbound ramp closures while crews prepare to replace the A-1 Mountain Road Bridge over Interstate 40 (exit 190):
- Westbound I-40 on- and off-ramps at A-1 Mountain Road (exit 190) will be closed from 6:30 a.m. Monday, April 18, through 5:30 p.m. Monday, May 2.
-
DETOUR TO A-1 MOUNTAIN ROAD: Westbound I-40 drivers accessing A-1 Mountain Road will be detoured to Hughes Avenue (Exit 185-Bellemont) to turn around and travel east on I-40 to access A-1 Mountain Road.
- Traffic from A-1 Mountain Road heading westbound on I-40 will first travel east on I-40 and then take Route 66-Exit 191 to turn around and travel westbound on I-40.
Drivers should proceed through the work zone with caution, slow down and watch for construction personnel and equipment.
The bridge replacement project is approximately 5 miles west of the junction with Interstate 17 in Flagstaff. For more information, visit https://azdot.gov/i40-A1-Mountain
