Do you know any tunnels where propane is restricted?

• Maryland/Baltimore: Baltimore Harbor and Fort McHenry (I-95) tunnels. Alternate route for RVs with propane over the Francis Scott Key Bridge is I-695.
• Massachusetts/Boston Harbor: All tunnels.
• Between Manhattan and Brooklyn: Brooklyn Battery Tunnel.
• Between Manhattan and Queens: Queens Midtown Tunnel.
• Between Manhattan and Jersey City: Holland Tunnel.
• Between Manhattan and Fort Lee: Lower level George Washington Bridge (I-95 South) and George Washington Bridge Expressway. Lower level Verrazano Narrows Bridge.

Do you all know any other tunnels where propane is restricted?

I have been through the harbor tunnel a dozen times - far right lane there is a sign - says RVs - they will ask you to turn LP valve off - then continue

Which way do you prefer & why? I travel I-95 a lot in a 39’ diesel pusher towing a 32’ enclosed car trailer- a buddy recommended going 695 west toward Towson but I was thinking of trying east on my next trip. At first glance it looked shorter but mapped out it is nearly the same, so I’m just curious what others prefer and why. Tolls are a concern too since my trailer is 3-axle. Thanks!

Is there an actual safe pull off before the tunnel??

According to MDTA, it’s prohibited, not just off.

There is always someone ruining a good discussion with interjection of actual facts from an authoritative source =

As a matter of fact they do, at least at the five restricted tunnels in the Norfolk Virginia area where I live. If you bypass stopping at the inspection station, where they verify the main valve is closed at the tank, the inspection station operator will halt STOP traffic entering the tunnel and you will be pulled out of traffic near the tunnel entrance and held until a state trooper can arrive and site you failure to obey highway sign (Virginia 46.2 830). The fine is $30 while the processing fee is $51. Welcome to the Redneck Riviera. Enjoy your stay and you'll come back now, ya hear.

I pass thru a HAZMAT/Propane restricted tunnel twice a day and I've seen plenty of RV owners with their rigs (driveable and towed) pulled off near the tunnel entrance.

And there are five, not four, in the southeastern Virginia area.

State Operated -
I64 Hampton Roads Bridge Tunnel
I664 Monitor Merrimac Bridge Tunnel
I264 Elizabeth River-Downtown Tunnel (Toll)
VA58 Elizabeth River-Midtown Tunnel (Toll)

Privately Operated -
US13 Chesapeake Bay Bridge Tunnel (Toll)

Sitting in the inspection station booth for 8 hours can be pretty boring so catching a wayward RV is probably high light of their day.

We frequently transit Baltimore and due to construction, tolls and the Key bridge traffic-ability itself we much prefer taking I695 west around the tunnel. It’s a few miles longer but time is the same and a much better ride.

Were based in Baltimore near both tunnels...I can say no doubt the toll facilities police are aggressive in writing citations/violations.

The short tunnel in Trenton NJ is also off-limits to RVs with propane.

[Habu77]

Both major tunnels in Pittsburgh prohibit LP tanks. Fort Pitt and Squirrel Hill.

Chesapeake Bay Bridge Tunnel allows propane tank but it has to be turned off

According to the MD DOT 10 lb propane canister (max 10) is allowed thru the tunnels. A standard home bbq canister holds roughly 20 lbs
