State Route 89A in Prescott Valley will be narrowed to one lane toward the top of Mingus Mountain (mileposts 331 to 338) between 7 a.m. and 5 p.m. on Tuesday and Wednesday, June 3 and 4 for pavement preservation work.

Flaggers and a pilot car will direct traffic in alternating directions through the work zone. The speed limit will be reduced to 25 mph and drivers can expect delays of up to 15 minutes.

ADOT advises drivers to proceed through the work zone with caution, slow down, and be alert for construction equipment and personnel.

Fines for speeding through a construction zone are doubled.
