 Traffic and weather on the 8th, and when it breaks, to Dave Dildine in the WTOP Traffic Center. Downtown roads around the National Mall, the East Street Expressway near the Tidal Basin and Washington Monument staying closed through the fireworks finale tonight. Memorial Bridge is closed. 395, 3rd Street Tunnel staying open. Many of the downtown freeway exits are not, and inbound traffic at the 14th Street Bridge is going to be heavy and probably getting heavier as more crowds build.
