The Arizona Department of Transportation advises drivers to plan for continued lane restrictions on State Route 89 in Prescott between Deep Well Ranch Road and State Route 89A until June 2019.

Contractors are widening the current two-lane roadway to a four-lane divided highway with a raised center median. The project includes a new roundabout at Perkins Drive, additional widening under the SR 89A overpass to accommodate left-turn movements in both directions, sound walls and new sidewalks.

During construction, one lane of traffic will be maintained in each direction with left turn restrictions in place.  Residential and business access will be maintained throughout construction.

Drivers should plan to use alternate routes and allow plenty of extra travel time.

The speed limit in the work zone is reduced to 35 mph. Drivers are asked to obey traffic control devices and use caution around construction personnel equipment.
