The Arizona Department of Transportation advises motorists to plan for overnight lane restrictions on Interstate 17 north of State Route 169 from Monday until Wednesday. Lane restrictions are needed for crews to apply a crack-seal treatment to the road to extend the life of the pavement. Restrictions will be in place from 7 p.m. to 7 a.m. with north and southbound travel narrowed to one lane. The speed limit will be reduced to 45 miles-per-hour in the work zone. ADOT reminds drivers to slow down and use caution when traveling near crews and equipment.
