Do you know any tunnels where propane is restricted?

It means turning off the propane at the tank.

You have to do that for the Alaska Ferry too. They check and hang a tag.

I live in the Baltimore area. I normally use the Francis Scott Key bridge, on the east side of the 695 beltway. The toll is the same as either of the tunnels, but a much shorter route than driving around the west side of 695. Also, the traffic around the west side can be horrible, particularly during rush hour.

Eight Fans....four fan rooms automatically handle ventilation inside tunnel.... can replace the tunnel's air in less than five minutes.

Not only that, but the signs have a generic "hazardous cargo" warning, not propane specific. I always drive through that tunnel in Baltimore. And why on earth would the lower levels of bridges prohibit propane? Makes no scientific sense.

In Hampton Roads -Norfolk Virginia we have 4 major tunnels that require RVERS motorhomes or trailers with propane to pull over for VDOT inspection prior to passing through any of the tunnels. The inspection booths are manned 24x7x365 all the pull overs are well marked and provide pretty good pull in & out lanes. Basically the inspector will come out take down your vehicle & trailer license # and ask if your propane is turned OFF. Often they just let you go but sometimes they will ask you to leave the vehicle and show them the gas tank is turned off. Minor pain in butt but failure to stop can lead to hearty fine if state police are around. Tunnels some with tolls all accept EZPASS
1. Hampton Roads bridge tunnel I64 no toll
2. Elizabeth river tunnel RT 17 Norfolk to Portsmouth Tolls EZPASS
3. Monitor & Merrimac tunnel I664 Newport News to Suffolk no tolls
4 Cheaspeake Bay Bridge Tunnel RT 13 Virginia Eastern Shore to Virginia Beach expensive TOLLS EZPASS

I believe any tunnel that says no hasmat materials means no popane

The George C Wallace and Bankhead tunnels in Mobile, AL The Bankhead tunnel also restricts all truck traffic and has only 12 foot clearance.

I'm sorry your beliefs are not fact.

Propane is not "hasmat" (sic).

But guess what is? Gasoline and Diesel.

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

AS a former LEO I believe they are referring to commercial trucks hauling Propane. Not a camper or RV with a small tank or (2) 40Lb tanks.

Sorry, but anything that requires placarding is HAZMAT. HAZMAT simply stands for hazardous material. Propane is placarded as a flammable gas with UN number 1978.

I have many years of CFR 49 experience.

Not necessarily.

The Washburn Tunnel goes under the ship channel, used to be a hassle going thru there, inspections, etc.


No reason to use it anymore. at least 3 bridges over the channel & a ferry.

• 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.

I have seen signs that say propane prohiited, usually some distance before the tunnel with instructions on alternate routes. As I recall, the Baltimore tunnels have this type of sign and most others that prohibit propane should have them too.
