Fort McHenry Tunnel-Baltimore, Maryland RPPC Postcard The Fort McHenry Tunnel is one of two tunnels that carry traffic underneath the Baltimore Harbor. It is named for Fort McHenry, which it passes close by. The tunnel, opened on November 23, 1985, closed a gap in the East Coast’s most important interstate route, Interstate 95, between Maine and Florida. It also is the largest underwater highway tunnel built by the immersed tube method and the widest vehicular tunnel ever built by that same method. At the time of its opening it was the most expensive underwater tunnel project in the United States, but that figure has since been surpassed by the Big Dig project in Boston. The Fort McHenry Tunnel is one of seven toll facilities operated and maintained by the Maryland Transportation Authority. The Fort McHenry Tunnel was constructed from June 1980 to November 1985, at a cost of about $750 million. The tunnel's annual traffic in 2003 was 44.1 million vehicles. The toll rate in 2008 for cars is $2.00, paid in either direction. Vehicles with more than two axles pay an additional $2.00 per extra axle. New Uncirculated Postcard  |
