 Route 50 eastbound, a long slog from Rowell Boulevard to the Bay Bridge, no two-way traffic. In the district, around the Washington Convention Center, street closures for the NATO summit. Add to that 9th Street, closer to P Street and Rhode Island Avenue for a second alarm fire department response. Near the old executive office building, 17th Street is closed today as a part of the summit closures. Constitution Avenue and 14th Street, though, are open.
