A five-car crash involving two semi trucks slowed north Interstate 205 Friday afternoon.
The crash was reported just north of Mill Plain Boulevard around 1:30 p.m., according to emergency dispatch logs.
The Vancouver Fire Department and Washington State Patrol are on scene.
WSP spokesman Trooper Will Finn said one semi is on the left median. The other four vehicles and first responder vehicles are blocking the right lane of traffic, Finn said.
Kevin Stromberg, a VFD spokesman, said one woman was sent to the hospital as a precaution after complaining of back pain.
