A motorcyclist died Friday afternoon on I-80 when he was forced off the roadway by a car that "cut him off," officials said.

The accident occurred at 1:44 p.m. and snarled traffic for nearly three hours while Summit County emergency personnel responded to the deadly accident near Jeremy Ranch. Authorities at the scene funneled slow-moving traffic around the eastbound accident by restricting movement to one lane.

A medical helicopter landed at a nearby rest stop and transported the man to the University Hospital in Salt Lake City where he was pronounced dead, said Summit County sheriff's officials.

The man, who officials say was in his 40s, was not wearing a helmet.

His name is being withheld until officials contact his immediate family.

No one else was injured during the accident.
