SOUTH KING COUNTY, Wash. - A woman was severely injured when her car was hit by a box truck along Interstate 5 in South King County during the Thursday morning commute, creating a huge traffic backup that lasted for hours, the Washington State Patrol reports.
All lanes have since reopened and the backup is clearing
Troopers and firefighters responded to the scene, just south of State Route 516 interchange, at about 6 a.m. after receiving reports of a serious collision.
The mangled remains of a wrecked car and a damaged box truck were found at the scene. The driver of the car was found with serious injuries and she was rushed to the hospital.
A preliminary investigation found that the woman's car was stopped on the shoulder when it was hit by the box truck. The truck driver was not impaired but may have fallen asleep at the wheel, said Trooper Rick Johnson of the State Patrol.
The two right lanes were blocked at the scene for about four hours and a traffic backup formed all the way to the Pierce County line at one point, state transportation officials said.
