MAPLE VALLEY, Wash. — All lanes of State Route 18 westbound just east of 256th Street in Maple Valley have reopened after being blocked following a crash involving a semi-truck Tuesday morning, the Washington State Department of Transportation (WSDOT) said.
Washington State Patrol Trooper Rick Johnson said in a tweet Tuesday that a stolen box truck used the median turnaround from eastbound on SR 18 before being struck by a semi-truck traveling westbound.
The driver of the stolen box truck was ejected in the collision, and was transported to the hospital with non-life-threatening injuries, Johnson said.
Traffic was getting by on the shoulder and emergency crews are on scene, but the backup is 2.5 miles according to WSDOT.
WSDOT also warns drivers that westbound Interstate 90 is reduced to one lane between Preston and Issaquah, meaning travelers should be prepared for delays on both SR 18 and I-90.
