All northbound lanes of Interstate 270 were closed between the Beltway and Rockledge Drive due to three separate crashes during Thursday's evening rush, fire officials say.
Some police vehicles were struck during the crash, according to Pete Piringer, a spokesman for the Montgomery County Fire and Rescue. The collisions happened just before 6:30 p.m., Piringer said.
All lanes reopened about an hour later, authorities said.
Five vehicles were involved in the collisions, Piringer said.
Medics evaluated three injuries. None are life-threatening.
