NO
No propane is allowed in the Baltimore tunnels, you must use the Scott Key bridge. There is propane allowed on the Chesapeake Bay Bridge Tunnel complex ( two 30# bottles and they must be turned off). If going through NYC there is no propane allowed through any of the tunnels from NJ to NYC and no propane allowed on the GWB except on the upper level only, it's best to go over the Tappenzee bridge. Also there is no RV's allowed on any of the parkways in NY either.
