Some lanes of the outer loop of the Beltway are closed Monday morning at Route 29 in Silver Spring due to a crash involving a major fuel spill. Maryland State Police said it is not known exactly when the Beltway will fully reopen in that area. Traffic is being diverted to other roadways, but officials advised drivers to avoid the area. In the earlier morning hours, all lanes on the outer loop side were closed, but just before 7 a.m., two of four lanes reopened. There were still major traffic delays on the outer loop of the Beltway.

Authorities said the crash occurred just before 2 a.m. when a state trooper stopped a vehicle in a “routine traffic stop” on the Beltway and the two vehicles were hit by a truck. The truck then apparently jack-knifed and spilled fuel on the Beltway. No one was seriously injured, but those involved were taken to area hospital. Crews are on the scene trying to clean up the wreckage and the oil spill.
