Two lanes on the Tri-State Tollway closed Friday in Hinsdale due to a crash.
A couple of semitrailers were involved in a crash about 5:50 a.m. near the Hinsdale Oasis in the southbound lanes, Illinois State Police said. Both drivers got out of their cars and stood on an embankment on the side of the road. No one was injured in the collision.
A HazMat team responded to the scene after one of the trailers leaked “a small vapor cloud” of hydrochloric acid solution that was damaged in the crash, state police said.
Two southbound right lanes were closed as crews worked to clear the area, and the southbound Hinsdale Oasis parking lot was evacuated, state police said.
Lanes were open again about 1:30 p.m. to all traffic after the vehicles were removed and the spill was contained, state police said.
Illinois State Police are investigating the crash.
