BRINNON — A motorcycle wreck on Dosewallips Road off U.S. Highway 101 near Brinnon has led to a motorcyclist and his passenger being taken by helicopter to Harborview Medical Center in Seattle for serious injuries, according to the Jefferson County Sheriff’s Office.

The conditions of the motorcyclists were not available Sunday.

At about 5:12 p.m. Saturday, a large group of motorcyclists were traveling eastbound on Dosewallips Road near Milepost 2, when the lead motorcyclist was unable to negotiate a curve and left the road, said Sgt. Mark Apeland.

The male driver suffered face and possible head injuries while his female passenger had a possible broken hip, Apeland said.

Both were taken by helicopter to Harborview for treatment of serious injuries, he said.

Apeland said the names of the pair have not been released because the wreck is under investigation as a possible vehicular assault.

Investigators believe alcohol may have been involved, Apeland said.

Harborview Medical Center policy does not allow release of medical conditions unless the name of a patient is known.
