ARCH CAPE - An 83-year old man died and four others were injured Wednesday evening in a two vehicle head-on crash on U.S. Highway 101 about one mile north of the Arch Cape tunnel, south of Cannon Beach.

Oregon State Police Sgt. Andrew Merila, said a 1994 Volvo four-door driven by Charles E. Nilson, was northbound on a straight stretch of Highway 101 near milepost 35 when it crossed the centerline and collided head-on with a southbound 2009 Chevrolet Avalanche pickup with two occupants.

Nilson, Lake Forest Park, Wash. was pronounced dead at the scene. His wife, Carol Nilson, 79, and daughter, Debra Nilson, 53, from Seattle, were transported by ambulance to Providence Seaside Hospital with non-life threatening injuries.

The Chevrolet's driver, Tom Watson, 64, and his wife, Sydnee Watson, 62, from Walla Walla, Wash., were transported by ambulance to Columbia Memorial Hospital. Sydnee Watson was treated and released. Tom Watson was transferred to Legacy Emanuel Hospital in Portland, where his condition was not known. Troopers said he was seriously hurt.

OSP troopers from the Astoria Area Command office and OSP collision reconstructionists are continuing the investigation into the cause of the crash. Cannon Beach Fire and Police departments, Medix Ambulance Service and Oregon Department of Transportation assisted at the scene. The highway was reopened at 12:30 a.m. Thursday.
