MONTGOMERY COUNTY, Maryland — A Monday morning crash involving more than 20 vehicles on Interstate 270 in Montgomery County left multiple people seriously hurt. It was declared a mass casualty incident, according to officials.
The Montgomery County Fire Department says medical crews evaluated more than two dozen people and had four taken to the hospital, including two with serious but non-life-threatening injuries.
Fire officials say the crash happened on I-270 in Middlebrook Road and Montgomery Village Avenue in Germantown after a tractor-trailer carrying stones and gravel crashed, losing its load. Police say the white tractor-trailer then left the scene of the crash and authorities are currently searching for it.
Officials say other cars could not avoid the tractor-trailer, leading to the crash. Police say they were called to the crash at around 5:20 a.m.
I-270 was closed going south but all lanes have now reopened but delays continue in the area.
Maryland State Police say they are investigating the crash with help from Montgomery County Police, the Maryland State Highway Administration and others.
