Trucks Allowed Inside City Perimeters?

Little Rock you can do either 40, 30 or 440. But 630 is prohibited to Hazmat.

Baltimore is 695 generally, Key Bridge in particular. No tunnels, no 895 (Old tunnel, man is that one getting old...) A word on the tunnels, they built them in sections at the shipyard, floated them out to the spot and sunk em. Then welded and patched them after getting the water out. I think these were 100 foot sections not sure. And there is a huge steel frame around the tube about two times the volume.
