Utah Highway Patrol Sgt. Mike Alexander said a car and pickup truck collided at state Route 224 and Olympic Parkway around 7 a.m. Oct. 7.
Alexander said both drivers had minor to moderate injuries.
The collision blocked multiple lanes on state Route 224 until around 10 a.m.
He said crash investigators needed extra time at the scene, delaying cleanup and adding to the traffic jam.
“Normally, we would save that for like very serious injury crashes, but in this case… our crash reconstruction team just decided, let’s go ahead and investigate it a little bit further,” Alexander told KPCW.
It was not immediately known what led to the crash Tuesday.
Traffic backed up on Interstate 80 in both directions for about 4 miles on either side of the Park City exit.
Drivers on nearby U.S. Highway 40 and state Route 248 heading into Park City proper were also heavily delayed.
Highland Estates resident Jon Weinberg told KPCW the backup was unusually disruptive.
“Today is definitely not normal,” Weinberg said. “Definitely one of the worst I’ve seen. Definitely concerned as more development comes and we build more at [Kimball] Junction. The traffic situation is just tough and we don’t even have skiing happening yet.”
The Utah Department of Transportation said the crash was cleared and traffic was returning to normal around 11 a.m.
