A section of the Pennsylvania Turnpike in Chester County that was shut down due to a tractor-trailer fire has reopened.

The Turnpike Commission said the road closure ended about 10:45 a.m. Monday.

Traffic in the eastbound lanes of Interstate 76 had been halted between Exit 312 in Downingtown and Exit 326 for Valley Forge for nearly three hours.

The tractor-trailer caught fire about 8 a.m. Monday.

Major delays were reported on the interstate, with backed-up traffic as vehicles were detoured off the highway.
