Trying to avoid an oncoming ambulance, a dump truck carrying a load of gravel overturned on U.S. Route 202 in Winthrop Tuesday morning and caused major traffic delays and minor injuries to the truck driver.

Winthrop Police Officer Timothy Falvey said rescuers cleared the accident shortly after noon. Traffic had been reduced to one lane since about 9:30 a.m., when a dump truck being driven west by 27-year-old Brady Joslyn of Whitefield overturned in the east-bound lane.

“It blocked both lanes for a while,” Falvey said.

Joslyn, who was alone in the truck, suffered minor injuries. The damaged truck is owned by Main Ex contractors of Augusta.

Joslyn was taking a load of gravel to a job site in Monmouth. He had just passed the Manchester town line and was cresting a hill that curves to the right when he pulled over to make way for an approaching ambulance with its emergency lights flashing. Falvey said the load in the truck shifted, and the truck turned over when Joslyn tried to correct his course.

The Winthrop Ambulance was answering a call in Manchester of an elderly man who was injured during a fall, according to Winthrop Police Capt. Ryan Frost.

Much of the dump truck’s load remained in the truck, but the portion that didn’t spread across much of the eastbound lane, Falvey said. Firefighters and Maine Department of Transportation crews, who arrived with a front end loader and truck, removed the remaining gravel from the road.

“Most of it was pretty well contained,” Falvey said.

Traffic was reduced to one lane for a few hours. At one point, cars backed up to the Route 17 intersection in Manchester.

“It took quite a while to get it flipped back over and then clear the roadway,” Falvey said.

Neither speed nor substances appear to have been a factor in the crash, Falvey said. Winthrop police did not anticipate charges.

The state police commercial vehicles unit also helped investigate the crash, Falvey said. He was unaware of any violation originating with that agency.
