The occupants of two vehicles were rushed to the hospital after a head-on crash that snarled mid-morning traffic on State Road 224 Tuesday in the Snyderville Basin.

A 50-year-old Park City man driving a Toyota Tacoma southbound toward Park City crossed the median near Bear Hollow Village and slammed a northbound Honda CRV driven by a 36-year-old woman from the Park City area, authorities say.

According to responders, paramedics airlifted the man in serious condition to University Hospital around 11:25 a.m.

The woman was taken to the same hospital via ambulance, Utah Highway Patrol trooper Preston Raban said.

"We still do not know the cause of the crash," he said, adding that investigators were still determining whether a passenger was riding in the Honda.

The names of those involved in the accident were not released Tuesday afternoon.
