 ADOT will soon begin a road safety project on Highway 169 between Grant Woods Parkway and the junction with I-17. Crews will install new rumble strips in the center lane and along the sides of the road and put down new pavement markings. In addition, a fog seal will be applied to help extend the life of the roadway. Work is scheduled for weeknights from 6 p.m. to 6 a.m.
