Fire crews arrived to find the semitruck buried deep in the mud of the westbound side of the highway, according to the department. No one was injured. According to the news release, the department worked with the Washington State Patrol to divert traffic at the scene, as well as the Washington Department of Ecology to investigate possible diesel and antifreeze leakage from the semitruck.
