MONTGOMERY COUNTY, Md. — A Beltway crashed that closed multiple lanes and caused a big traffic backup on Monday started with an overturned box truck, Maryland State Police said Tuesday.
MSP investigators said a box truck struck a jersey wall on I-495 northbound before MD-190 near the River Road exit just before 1 p.m. The initial crash caused a chain-reaction crash involving six vehicles. The truck also lost its load of sheet metal, which led to a lengthy clean up process.
All lanes of the Inner Loop in the area were blocked as crews worked to investigate the crash and clean up debris on the road. Two of the left lanes of the Outer Loop were also blocked with two right lanes getting by. Clean-up efforts lasted about three hours.
Montgomery County Fire Department Spokesperson Pete Piringer tweeted the crash involved an overturned vehicle. Piringer said three patients were taken to the hospital for injuries sustained in the crash. Those injuries were not thought to be life-threatening. All those hospitalized are expected to recover.
It is not clear what caused the box truck to strike the jersey wall in the first place. Additional information was not immediately available.
