A critically injured Juneau motorcyclist was flown to Seattle for treatment Saturday night, after the Juneau Police Department says he rear-ended a vehicle which was stopped to make a turn.

In a Saturday statement, JPD Sgt. Chris Burke says the 49-year-old male was injured in a two-vehicle collision, on Glacier Highway near its intersection with Sunny Drive. The wreck was reported to police just before 6:15 p.m.

“The preliminary investigation indicates that a 2007 Chevy Impala was stopped in traffic attempting to turn onto Sunny Drive,” Burke wrote. “A 2000 Honda Nighthawk 750cc motorcycle was traveling outbound (toward the Mendenhall Valley) on Glacier Highway and struck the back end of the Chevy.”

While the 29-year-old local man driving the Impala was uninjured, the motorcyclist was initially taken to Bartlett Regional Hospital for treatment of his injuries. JPD was informed at about 10 p.m. Saturday that he was medevaced to Harborview Medical Center in Seattle.

A JPD dispatcher says no further information on the crash, including the drivers’ identities or whether police believe drugs, alcohol or speed were factors, is immediately available Sunday morning.

According to Burke, police are still investigating the crash.
