PHOENIX — Just in time for the busy Memorial Day holiday weekend, the Arizona Department of Transportation lifted all traffic restrictions along State Route 87 at shortly before 6 p.m. Wednesday, May 20, as the agency nears completion of a safety improvement project approximately 10 miles north of Sunflower near the Maricopa/Gila County line.

Since construction started in October, motorists traveling between Phoenix and Payson have encountered a series of traffic restrictions related to a $6.2 million project to reconstruct an existing curve to make it easier for vehicles to navigate through at milepost 227, as well as building a new northbound truck escape ramp at milepost 228.

In addition to all four lanes (two in each direction) being reopened through the work zone, all wide load restrictions were removed permanently as well.

The project also includes slope excavation and reconstruction, drainage improvements, new signage and new concrete barrier installation. 

The new runaway truck escape ramp will 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 truck escape ramp is scheduled to open next month, but there will not be an impact to the traveling public as the remaining work on that project will be completed away from the four-lane highway.

Beginning Tuesday, May 26, drivers may encounter intermittent lane restrictions in both directions for miscellaneous work through the end of June.

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.
