The Arizona Department of Transportation is reminding residents and travelers of overnight lane restrictions on State Route 69 this week. Lane restrictions are needed for crews to work on a $2.6-million pavement preservation project. State Route 69 will be narrowed to one lane in each direction between Onyx Drive in Mayer and Main Street in Dewey-Humboldt, a 14-foot vehicle-width-limit will be in place, and the speed limit will be reduced. Restrictions will be in place Sundays through Thursdays from 8 p.m. to 6 a.m. until September 30th. ADOT reminds residents and travelers to slow down and use caution when traveling near crews and equipment.
