BREAKING: Inner Loop Closed Due to Tanker Truck Crash

Update at 3:55 p.m. — Tow crews are on scene and one far left lane is now temporarily squeezing by the crash, but VDOT says it will soon completely close the highway again. The closure, which is expected to last throughout the rush hour, is causing serious traffic issues across the area.

The Inner Loop of the Beltway is closed for an extended period of time due to a truck crash prior to the American Legion Bridge.

Fairfax County Fire and Rescue say the tanker truck, which overturned on northbound I-495 near the Great Falls exit, is “actively leaking” 8,500 gallons of hazardous fluid, initially reported to be fuel.

Hazmat crews are “aggressively” working to contain the leak, but the Inner Loop is expected to remain closed for at least two hours and possibly longer, well into the evening rush hour.

Only one minor injury was reported.

The crash was caught on a dashcam, per a video posted on social media.
