Authorities said it left multiple people seriously injured and was declared a mass casualty incident.
Medical responders evaluated over two dozen people and took four to the hospital, the Montgomery County Fire Department said. Out of the four, two had serious but non-life threatening injuries, ABC affiliate WJLA-TV reported.
Police said the incident was caused by a tractor-trailer which cut off a car. It set off a chain-reaction crashing involving another tractor-trailer carrying slate, which spilled its load across the busy roadway at about 5:20 a.m.
The vehicles behind the tractor-trailer were unable to stop in time to avoid the slate, NBC Washington reported.
Helicopter footage shows multiple vehicles with serious damage. The emergency response also appeared to be massive.
All of the southbound lanes of the I-270 were closed for several hours. But the road has since re-opened as of writing. Delays remain in the area.
