Road & Tunnel Restrictions near Maryland


Fort McHenry Tunnel RestrictionsDifferent roads have different restrictions when it comes to travelling with an RV – it’s generally geared around the propane tanks that are being carried. A couple of those are:

  • Fort McHenry Tunnel on I-95 near Baltimore, MD – no propane tanks allowed* (see details)
    • An alternate route is to take the I-695 Beltway either north or south
  • Baltimore Harbor Tunnel on I-895 near Baltimore, MD – no propane tanks allowed* (see details)
    • An alternate route is to take the I-695 Beltway either north or south
  • Pennsylvania Turnpike Tunnels in western PA – propane tanks must be off (email response below)
  • Chesapeake Bay Bridge in Maryland (major route to the Eastern Shore and points beyond- like Ocean City, MD) – no propane restrictions, but depending on weather there may be wind restrictions; use their website for guidance
  • Chesapeake Bay Bridge Tunnel in Virginia – propane tanks must be off (see details)
    • There is supposedly are convenient pull off areas with which you can stop to turn propane off and later back on
  • Baltimore/Washington Parkway in Maryland – no propane restrictions, but no commercial trucks and height restrictions

For the tunnels near Baltimore, the alternate routes are to take the I-695 Beltway around Maryland. Different people have different preferences for going the topside (north) or bottom (south) of the beltway. Going the top side can be more traffic, but no tolls; going the south side, you’ll go across the Francis Scott Key Bridge which has a toll, but generally lesser traffic. The south side is my preference.

Pennsylvania Turnpike Tunnels:

Thank you for taking the time to contact the Pennsylvania Turnpike Commission. In response to your email you are permitted to carry up to 100 pounds of propane through the tunnels at one time. The only restriction is it must be turned off only while traveling through all of the tunnels.
