Several cars were reportedly involved in a major crash on Interstate 5 south of SR 516 in Kent on Sunday afternoon, causing a three-mile backup. The southbound lanes are closed.
Trooper Rick Johnson of the Washington State Patrol said there were minor injuries in some of the crashes. But the patrol is currently unsure how many total cars are involved.
Tow trucks are currently on site.
Several first responders and agencies are on scene, including officials from the Washington State Patrol, the Washington State Department of Transportation and local paramedics.
The backup is 3 miles and growing, WSP and WSDOT officials said.
There is no estimate for how long southbound I-5 will be closed. According to WSDOT, people should expect additional travel time and seek alternate routes.
