Work continues on State Route 87 north of Sunflower

Delays are expected this month as traffic is diverted onto northbound lanes

PHOENIX — Motorists traveling between Fountain Hills and Payson this month are urged to allow extra travel time as all State Route 87 traffic will be shifted to the northbound lanes beginning Thursday, April 9, as part of an ongoing safety improvement project north of Sunflower from mileposts 223 to 229.

Traffic in both directions will use the northbound lanes to form a two-lane roadway through the work zone. A 10-foot width restriction will be in place through April 24.

Delays up to 30 minutes are possible.

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 to make it easier for motorists to navigate, as well as building a new northbound truck escape ramp at milepost 228. Runaway truck ramps offer an opportunity for an out-of-control truck, which may have inoperable brakes, to safely exit the highway and come to a controlled stop.

The project is scheduled to be completed prior to the Memorial Day holiday.

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.
