More than 100 cars were disabled after a tanker carrying driveway sealant leaked the gooey muck for 40 miles on the eastbound lanes of the Pennsylvania Turnpike between New Castle and Oakmont Service Plaza on Tuesday night.

Traffic had returned to normal by this morning after work crews used plows and sand to contain the sticky substance.

“This stuff will eventually dry. Now, that doesn’t help all the people that got some of this material on their cars, and we know there are many of those,” Pennsylvania Turnpike spokesman Bill Capone told ABC News Pittsburgh affiliate WTAE-TV.

WTAE spoke with tow truck driver Tony Armenti who said the disabled cars will likely be costly to fix.

“That tire’s gonna have to be replaced. The rim’s gonna have to be replaced, and the rest is gonna have to be taken off,” he said.

For some it was more than just another inconvenience going into one of the biggest travel days of the year.

“This is Thanksgiving. Now we have to turn around and go back home,” Laura Frick, who was traveling from Cleveland to New Jersey told WTAE. “It’s horrible.”
