Part 1; the history of the Fort McHenry Tunnel
As referenced in the introduction the Fort McHenry Tunnel was the final segment of Interstate 95 to be completed in the city of Baltimore. Prior to the completion of the Fort McHenry Tunnel the majority of limited access traffic used the Baltimore Habor Tunnel which had opened to traffic on November 29, 1957, as part of the Harbor Tunnel Throughway. The entirety of the Harbor Tunnel Throughway was designated as Interstate 895 during 1979 as a non-chargeable Interstate.
A bridge was first considered as the final link for Interstate 95 in Baltimore over Baltimore Harbor. The bridge concept was ultimately deemed to be undesirable due to the impact on the aesthetic of Fort McHenry and Locust Point. The final design for Interstate 95 under Baltimore Harbor consisted of four sunken tubes which would span 1.5-miles from Locust Point to Lazarette Point. Construction of the Fort McHenry Tunnel broke ground during June 1980 and would open to traffic on November 23, 1985. The Fort McHenry Tunnel was completed at an approximate cost of $750,000,000.
