enable dual track, lots of rescue vessels at the bridge and no merchant traffic it looks like everyone is queueing up outside the harbor figuring out what to do
If you slide down south of the Bay Bridge, there are about 12 ships anchored there. I usually a few when I cross the Bay Bridge, so I'm not sure if that's a larger-than-usual amount. You have to figure that the ship that was leaving would have triggered another one inbound before long; I doubt they normally leave the dock empty for any longer than absolutely necessary.
And the tunnels (I-895 and I-95) forbid things like propane, so if you have some of that, you're off to the west side of the Baltimore Beltway, which is already extremely busy. Good luck with that!
(Relatively local person here who travels around Baltimore frequently. I've used the bridge that collapsed on several occasions to avoid the tunnels while carrying propane.)
Except if you’re carrying HAZMATS it’s even worse, they’re not allowed in either of the tunnel crossings, so all that traffic has to reroute aaaaaaall the way off your map via the western half of 695.
