Fort McHenry Tunnel (I-95)

 

Fort McHenry TunnelWhen it opened to traffic in November 1985, the Fort McHenry Tunnel was the largest underwater highway tunnel, as well as the widest vehicular tunnel built by the immersed tube method in the world. The eight-lane tunnel is nearly 1.4-miles long and connects the Locust Point and Canton areas of Baltimore, crossing under the Patapsco River, just south of historic Fort McHenry. The tunnel is a vital link in I-95, the East Coast's most important interstate route. Including the tunnel and approach roadways, the facility is approximately 10.3 miles in length.
