 In the district, though, it might get a little wetter where the road closures are in place for tonight's fireworks show. All the roads surrounding and across the National Mall remain off-limits to drivers, but not pedestrians, of course. And if you're coming in on 395 at the 14th Street Bridge, it'll be a little sluggish. Exit 1 for 14th Street, exit 3 for the 12th Street Expressway, both closed. Third Street Tunnel is going to stay open, along with the Roosevelt Bridge and Key Bridge.
