Fuel spill snarls traffic after multi-vehicle crash on I-495 in Montgomery County

Montgomery County, MD – A crash involving multiple vehicles and a tractor-trailer shut down several lanes on the outer loop of I-495 Wednesday morning, causing a fuel spill and major traffic delays in Montgomery County.

The collision occurred just past the Clara Barton Parkway on I-495 South and involved a heavy wrecker that was towing a tractor-trailer along with three other vehicles, according to Montgomery County Fire and Rescue officials.

Crews responded to the scene around dawn and blocked off several lanes to contain the spill and manage the wreckage. Authorities have not confirmed the extent of any injuries.

Fire and hazmat teams were called in to address the leaking fuel, which required cleanup before traffic could safely resume. Officials have not provided an estimate on how much fuel was spilled or how long the lane closures would remain in place.
