A tractor trailer traveling on I-95 near Rosedale in Baltimore County caught fire Thursday evening, prompting lane closures and major traffic jams up to six miles.
The tractor trailer was carrying multiple vehicles, a few of which also caught fire, said fire department spokesman Tim Rostkowski.
No injuries have been reported, he said, but there was a “significant” fuel spill.
The Maryland Department of Environment and a hazmat team responded to the scene, Rostkowski said.
Around 9 p.m. Thursday, all lanes had been reopened.
