A crash on I-270 North near Democracy Boulevard in Montgomery County is snarling traffic on the Capital Beltway, creating heavy delays just as the afternoon rush hour gets underway.

The accident on I-270 North near the spur temporarily closed all lanes, resulting in delays that jammed the inner loop of the Beltway from I-270 back to the Dulles Toll Road.

Two lanes on I-270 North reopened shortly before 5 p.m., leaving one lane and one of the shoulders blocked. [5:03 P.M. Update: All northbound lanes have reopened, though one of the shoulders remains blocked.] But serious delays remain, and commuters heading to this area of the Beltway should be prepared for heavy traffic.
