Ted Williams Tunnel

The Ted Williams Tunnel (planned as the Third Harbor Tunnel, the Sumner and Callahan Tunnels being the first two) is the tunnel connecting South Boston with Boston's Logan International Airport. It carries the final leg of the Massachusetts Turnpike (Interstate 90) under the Boston Harbor allowing direct access to Route 1A in East Boston.

It was the first major link constructed as part of Boston's Big Dig. It is constructed from ten steel sections fabricated in a Baltimore shipyard. These sections were then brought near the site and each was fitted with a large surrounding mass of concrete (so that the completed tunnel wasn't buoyant). Using additional flotation, the tunnel sections were then floated into place, sunk, and joined to the other sections. At this point, the steel panels sealing the now-joined sections could be cut out and the finishing operations could commence.

The TWT opened in 1995, but initially, only commercial traffic was allowed to use it. Later, non-commercial traffic was allowed on weekends and holidays. Since 2003, with the substantial completion of the I-90 portion of the Big Dig, the tunnel is open to all traffic at all times.
