The Ted Williams Tunnel sits 90 feet beneath Boston Harbor. It is the deepest underwater connection in North America. This path carries the Massachusetts Turnpike to Logan International Airport.
Workers built twelve binocular steel sections in Baltimore. They shipped these pieces to Black Falcon Pier. They wrapped the steel in thick concrete to achieve neutral buoyancy. Engineers floated the sections into a channel and joined them.
Commercial traffic only used the tunnel in 1995. Everyone else waited until 2003. The tunnel spans 8,448 feet. Nearly 4,000 feet of that length stays underwater.
Look for the bronze memorial by Robert Shure during your drive. It honors a Red Sox legend. The tunnel bears his name.
