An Ashland woman on her way home from her shift as a 911 dispatcher died when a Grants Pass man driving the wrong way on I-5 slammed into her car, ejecting her from the vehicle, Oregon State Police reported.

Karen Lee Greenstein, 58, was driving her 2006 Honda Civic just after 3 a.m. today near milepost 24. A 2003 Dodge Grand Caravan, driven by 32-year-old Richard Webster Scott, was driving northbound in the right hand southbound lane and drove into her vehicle head on.

Greenstein was pronounced dead at the scene. She was an employee of Emergency Communications of Southern Oregon for more than 20 years, police reported.

Scott was extricated and taken to Asante Rogue Regional Medical Center with serious injuries. His current condition at the hospital was not immediately available.

OSP said the case remains under investigation and are asking any witnesses who saw the van driving prior to the crash to call their Southern Command Center dispatch at 541-776-6111. Officials reported a vehicle matching the van's description was seen sideways on the southbound off ramp at exit 21, about three miles south of the scene.

Alcohol likely contributed to impairing Scott, police said. The southbound lanes of I-5 remain closed while an accident reconstruction continue to investigate the crash. OSP anticipates the lanes will remain closed until about noon.

Oregon State Police say alcohol impaired the male driver who drove the wrong way on I-5 this morning, causing a head-on collision that killed a woman near milepost 25.

"We're looking at alcohol as a contributing factor," said Lt. Gregg Hastings of OSP. "This is considered a criminal investigation at this point."

The names of the woman who died and the driver still have not been released.

A driver heading north in the southbound lanes of Interstate 5 this morning allegedly caused a car crash that killed one near milepost 25, Oregon State Police reported.

Currently, both southbound lanes of I-5 are closed. Southbound traffic is being diverted at exit 27 onto Highway 99. Motorists can get back on the interstate at exit 21 in Talent. Oregon Department of Transportation officials said to plan for delays and congestion.

"We expect the soutbound lanes to be closed at least through the morning commute due to crash reconstruction," said ODOT spokesman Gary Leaming. "This'll be an extended closure."

OSP says the crash happened just after 3 a.m. near milepost 25. A driver was traveling north in the southbound lanes when they crashed into another car. OSP, the Jackson County Sheriff's Department, Jackson County Fire District 5 and ODOT responded to the scene. The motorist driving the wrong way, whose name has not yet been released, was extricated from their vehicle and taken to a local hospital with unknown injuries.

A traffic crash reconstruction is underway at the accident site, necessitating the detour. OSP, sheriff's department officials, Medford police, ODOT, and fire personnel remain on scene. Additional information, including name of the person killed in the crash, is not yet available.

We will update this story as more information becomes available.
