A dump truck crashed into two cars in the area of the Old Town roundabout on Wednesday morning, the Park City Fire District said, another in a long-running string of accidents blamed on the steepness of a stretch of Marsac Avenue.

The Fire District said the truck was northbound on Marsac Avenue, the downhill direction, when it “went through the roundabout” and hit the two cars. The accident occurred at 9:25 a.m.

The Fire District said three people were transported from the scene for treatment. The people were in stable condition at the time they were taken away, the Fire District said. The Utah Highway Patrol, which investigated the accident since Marsac Avenue is part of the state highway system, said the injuries were minor.

The Utah Highway Patrol said the two vehicles hit by the dump truck are a Ford passenger car and a BMW sport utility vehicle. The agency said the dump truck was carrying a load of dirt at the time of the accident. The brakes failed prior to the accident, according to the Utah Highway Patrol.

The Fire District said the crash forced a road closure since power lines were taken down as a result of the accident.

There has been a series of accidents over the years on that stretch of Marsac Avenue blamed on brake failures. Marsac Avenue between Old Town and upper Deer Valley is an especially steep road. Brake failures can send trucks careening down Marsac Avenue and into the area of the roundabout. A truck-escape lane is located on Marsac Avenue, but it has not prevented all runaway-truck accidents.

Images from the scene posted by the Fire District show the truck violently struck a stone wall and came to rest on the other side of the wall. One of the images shows the truck suffered extensive damage to the front.

The Utah Highway Patrol indicated the investigation was continuing.
