ADOT says drivers who use I-17 should plan for daytime alternating north and southbound lane restrictions between Highway-169 and 69. Restrictions will occur daily from 5-am-to-5-pm starting Wednesday and continuing through August 26-th. North-and southbound I-17 will be narrowed to one lane in each direction between the junctions with 169 and the junction with Highway-69. Restrictions are needed for maintenance crews to apply a fog-seal treatment to the roadway.
