An accident on the outer loop of the Beltway after the exit for Ritchie Marlboro Road is blocking the two left lanes, creating major delays for travelers already slowed by the weather.

The crash is blocking two lanes and the shoulder. Traffic is inching by at this point, with a sea of taillights visible on traffic cameras in the vicinity.

Commuters across the region should expect to encounter delays this afternoon and evening due to the rain. Even if it’s not raining when you head out, the roads will be slick and traffic will be slow. Be prepared for a long, slow commute home.
