WASHINGTON — Several people were injured in two separate crashes that caused major delays on the Capital Beltway in Montgomery County on Wednesday afternoon.

The two crashes happened on the Beltway’s Inner Loop around 4 p.m., says Montgomery County Fire and Rescue Spokesman Pete Piringer.

Fire and Rescue units responded to a crash between the exits for Georgia and Connecticut avenues at around 4 p.m. While crews were responding to the first crash, a vehicle hit an EMS unit meant to protect workers from oncoming traffic, Piringer says.

That car overturned and the driver was briefly trapped and taken to the hospital with potentially life-threatening injuries, Piringer adds.

Three other people received minor injuries, including the driver from the initial crash. No firefighters suffered injuries, Piringer says.

The crashes and clean up caused the Inner Loop’s lanes to close Wednesday afternoon. All lanes reopened by about 5:30 p.m.
