Overnight lane restrictions on State Route 89A (Milton Road) in Flagstaff August 7-12

FLAGSTAFF – The Arizona Department of Transportation is advising motorists to plan for overnight lane restrictions on State Route 89A (known locally as Milton Road) in Flagstaff during the final stages of work on a pavement rehabilitation project.

Drivers should slow down, proceed through the work zones with caution and watch for construction personnel and equipment while the following restrictions are in place daily from 7 p.m. to 7 a.m. starting Sunday night, August 7, and ending Friday morning, August 12:

  • Portions of north- and southbound SR 89A will be narrowed intermittently to one lane in each direction between Forest Meadows Street and Phoenix Avenue.
  • A vehicle width limit of 16 feet will be in place.
  • The speed limit will be reduced to 25 mph.


The restrictions are needed as crews continue working on sidewalks, driveways and curb ramps. Crews have completed the most significant work on the project, which was to remove the existing pavement and replace it with new asphalt. For more information, visit the project web page.
