The Arizona Department of Transportation is reminding motorists of overnight lane restrictions on State Route 89 in Chino Valley beginning Tuesday. Restrictions will be in place as crews complete drilling operations just north of the Center Street intersection. Both north and southbound State Route 89 will be reduced to one lane in each direction and a ten-foot vehicle width limit will be in place. Restrictions will begin Tuesday at 9 p.m. and be lifted at 5 a.m. on Thursday. ADOT reminds residents to slow down and use caution when traveling near crews and equipment.
