“The truck was hauling several totes of a resin-polyurethane substance,” said Ryan Frazee, Emergency Planner with the Washington County Department of Public Safety.

The substance was in large blue tanks that were carefully being pulled out of the trailer.

“And we had a large release of motor oil, diesel fuel and some of that polyurethane,” said Frazee. “We’re trying to protect the waterways and it did get into some storm drains, but we have the spill contained.”

The crash happened just after 1 a.m Friday.

The focus was on getting the driver out, but unfortunately he did not survive. For hours, crews remained on scene and had the heavily traveled road closed.

“There was a time where 70 eastbound was closed and the ramps to 79 southbound were closed.”

It is not clear what caused the crash.
