ADOT crews will be working on repairing southbound lanes of Highway 89 Tuesday through Thursday in Doney Park, north of Flagstaff. Work will narrow the highway to one lane for two miles from milepost 436 to milepost 434 Tuesday. Highway 89 will be narrowed to one lane for a mile from milepost 433 to 432 Wednesday and Thursday. Lane restrictions are needed so crews can perform pothole and shoulder repairs due to flooding to the highway. Restrictions will be in place from 7 a.m. until 3 p.m. each day. Drivers should anticipate delays and the speed limit will be reduced in work zones.
