State Route 89 Improvements Between Road 4 and Deep Valley Ranch Road

Traffic Alerts

Dirt haul on SR 89 between Prescott and Chino Valley scheduled next week

Drivers can expect minimal delays overnight

Traffic on State Route 89 between Prescott and Chino Valley will be required to stop intermittently next week to allow trucks to safely cross the highway.

The hauling operation will take place from 8 p.m. to 5 a.m. Monday through Thursday, March 30 through April 2, with intermittent closures for dirt hauling. Drivers can expect minimal delays during work hours.

The work zone will be clearly marked by temporary barricades and signage. ADOT advises drivers to allow additional time to reach their destinations and to proceed through the work zone with caution, comply with the reduced speed limit, and be alert for construction equipment and personnel. 

Upon completion of the $17 million project, ADOT will expand the two-lane roadway to a four-lane divided highway along a five-mile segment of SR 89 (mileposts 320-325) between Road 4 South in Chino Valley and Deep Well Ranch Road in Prescott, just north of the SR 89/SR 89A junction. The project is expected to be complete by August.
