Two options, both involve the Eastern Shore.
301 S, over the Bay Bridge. No toll westbound. Continue 301 S over the Potomac & then whatever after that. 301 continues to more or less parallel 95 but is a real nice, quiet, 4 lane road for a long way.
The other is 13 S through DE & on to the CBBT to Virgina Beach. Who told you no propane on the CBBT? They are WRONG. Done it many times. SB, pull over just before toll at N end & turn the propane off. That is all that is required.
The trip over & under on the CBBT is an experience all by itself. 20 miles of bridge & 2 deep tunnels.
