July 26, 2024

With the closure of a portion of I-695, motorists are being encouraged to use the I-95 or I-895 tunnels as alternates; however, trucks should be aware of the following restrictions. Vehicles in excess of 13’6” in height, or 96” (8 feet) in width are prohibited from using the Baltimore Harbor Tunnel (I-895). The I-95 Ft. McHenry Tunnel restrictions are 14’6” height and 11’0” in width.

Most hazardous materials are prohibited in the tunnels and should use the western section of I-695. A list of the specific prohibitions on various commodities is laid out in COMAR 11.07.01.04, which is available at https://dsd.maryland.gov/regulations/Pages/11.07.01.04.aspx.
