Work continues on State Route 87 north of Sunflower

Delays are expected Monday as northbound traffic travels on southbound lanes

PHOENIX — Motorists traveling between Phoenix and Payson on Monday, Jan. 26 are urged to allow extra travel time as northbound traffic will be restricted as part of a safety improvement project on State Route 87 north of Sunflower from mileposts 223 to 229.

From 2 a.m. through 8 p.m. on Jan. 26, northbound SR 87 traffic will be stopped at the work zone and southbound SR 87 will convert to a two-lane roadway as northbound drivers will be guided through the work zone with a the aid of a pilot car. Delays of up to 30 minutes are possible. 

The work, which was originally scheduled for this week, was rescheduled due to material delays.

The $6.2 million safety improvement project, which began in October, approximately seven miles south of the State Route 188 junction, includes the reconstruction of an existing curve at milepost 227, as well as building a new northbound truck escape ramp at milepost 228. Runaway truck ramps offer an opportunity for out-of-control trucks, which may have inoperable brakes, to safely exit the highway and come to a controlled stop.

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. 

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.
