Overnight Dirt Haul on SR 89 Between Prescott and Chino Valley Continues

Drivers can expect overnight delays of up to 10 minutes for the next three weeks.

Traffic on SR 89 between Prescott and Chino Valley (mileposts 320 to 325) will be required to stop intermittently, weather permitting, for the next three weeks to allow trucks to safely cross the highway.

The hauling operation will resume on Monday, April 20 and continue through Friday, May 8.

Overnight work hours are Monday through Friday between 8 p.m. and 5 a.m. each night, and intermittent closures are expected for dirt hauling.

Drivers can expect delays of up to 10 minutes at a time.

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 to 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.

ADOT works to inform the public about planned highway restrictions, but there is a possibility that unscheduled closures or restrictions may occur. Weather can also affect a project schedule.
