The State Patrol said a 34-year-old man died in a head-on crash that involved a semi truck and two cars along Highway 18 near Issaquah-Hobart Road.
A blue Subaru was heading east on Highway 18 when the driver crossed the center line and crashed into an oncoming semi truck.
"The semi truck... they collided, I think the rear part of the semi ran over the front of the blue Subaru," said Trooper Kelly Spangler. "That's the first collision."
The second collision was quick to follow. The driver of a white pickup truck was suddenly engulfed in the smoke and debris from the accident and didn't see the wreck.
That pickup ran right into the already smashed up Subaru, and the injured driver.
The Subaru driver died.
The backup quickly stretched for miles, with a long-time truck driver at the front of the line.
"You never get used to it," said Spencer Strayberry. "I've been doing it (truck driving) a long time. You just ask God to help those people. And bless the families in the fatalities. It's just one of those situations that's always difficult."
Troopers don't know yet why the Subaru crossed the center line. But because this is a highway, they figure the driver was going at least 60 miles an hour.
"Physics takes over," Spangler said. "You're gonna have things peppered all over the roadway. The road will be shutdown for a significant amount of time because every single piece that has come from a car or semi is evidence."
The road was closed for nearly five hours before reopening around 11 o'clock. The driver of the semi was not injured. The driver of the pickup truck had minor injuries and was taken to a hospital just to be checked out. He was released a short time later.
Police do not believe alcohol was a factor.
The victim's name has not been released.
