Wow, hoping for the best for the workers on the bridge. You can see maintance vehicle with their flashing lights on stopped on that bridge, and all of them went into the water.
As far as traffic, that's a major bridge that carries Interstate 695. Traffic is going to be super-fugged for a long time to come.
As far as blocking in the Navy, that's not an issue. There may be some USNS ships in that harbor for repair or for taking on fuel. But the bulk of the Navy is in Norfolk, Va and some other bases on the east coast.
