First responders were called shortly before noon on Sept. 6 to the eastbound lanes of the interstate, where the rear of the truck caught fire, leading to lane closures, officials said.
The incident was reported between Connecticut Avenue and Georgia Avenue.
A Montgomery County Fire and EMS spokesperson said that the fire was quickly extinguished, and there was no extension to the cargo, though the tractor-trailer had to be towed from the scene, leading to additional delays.
Just one fire truck was still at the scene as of 12:15 p.m. on Friday, though there were still residual delays with one right lane blocked.
It is unclear what caused the fire.
