MONTGOMERY COUNTY, Md. (WJLA) - A Monday morning crash involving more than 20 vehicles on Interstate 270 in Montgomery County left multiple people seriously hurt and was declared a mass casualty incident, according to authorities.
The Montgomery County Fire Department says medical crews evaluated more than two dozen people and have taken multiple to the hospital with injuries, including some that are serious.
Fire officials say the crash happened on I-270 in the area of Middlebrook Road and Montgomery Village Avenue after a tractor-trailer carrying stones and gravel crashed, losing its load. Officials say other cars could not avoid the tractor-trailer, leading to the crash.
