The Arizona Department of Transportation is reminding Flagstaff drivers of upcoming overnight lane restrictions on Milton Road again this week. Lane restrictions are needed for crews to remove existing pavement, replace curbs, sidewalks and driveways, and replace the pavement on the roadway. Both north and southbound travel on Milton Road will be narrowed to one lane, a speed limit of 25 miles-per-hour will be in place, and there will be a vehicle width limit of 16 feet. Overnight lane restrictions will be in place from 7 p.m. to 7 a.m. Road work is expected to be completed by Friday morning. ADOT reminds drivers to slow down and use caution when traveling near crews and equipment.
