Officers investigated two accidents at Corvair Curve Friday, one that likely resulted from the rain and the other from speeding.
About 5 p.m., a semi truck jackknifed in the steep curve south of town on Highway 87 (milepost 246), blocking travels for several hours, some of which had to rebook holiday flights.
The semi was reportedly heading south when the driver lost control and struck the back end of a pickup truck in the other lane. The driver of the pickup was able to stop and pull to the side. The driver of the semi, however, lost control and jackknifed, said Sgt. Erik Axlund with the Arizona Department of Public Safety.
The semi driver was likely going too fast for the curve, Axlund said. He was cited for speeding.
The southbound lanes were closed for some time to remove the truck. One traveler, who was headed to Phoenix Sky Harbor International Airport, said they had to rebook their flights for Saturday because of the highway closure.
Earlier in the day, just before 4 a.m., a passenger vehicle rolled at Corvair Curve. The 2007 Chevrolet sedan was heading south when the driver lost control, likely due to the slick roadway conditions caused by a winter storm, Axlund said.
Three people were treated and released at Payson Regional Medical Center.
The driver will not be charged in that incident, Axlund said.
