ADOT says drivers should plan for overnight lane restrictions on north and southbound Highway-69 in Prescott Valley. Restrictions will occur nightly from 7-pm to 6-am starting Sunday through Friday. North and southbound Highway-69 will be narrowed to one lane in each direction between the junction with Highway-169 and Navajo Drive. Closures are needed for maintenance crews to apply a crack-seal treatment to the roadway.
