History
The Ted Williams Tunnel (TWT) was the first major link constructed as part of Boston's Big Dig. It is constructed from twelve "binocular" shaped steel sections fabricated in a Baltimore shipyard. These sections were then brought to the Black Falcon Pier near the site and each was fitted with a large surrounding mass of concrete (so that the tunnel section was more neutrally buoyant). Using additional flotation, the tunnel sections were then floated into place, lowered into a dredged channel, 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 be completed.
When the TWT opened in 1995 it was only available to authorized commercial traffic. Later, non-commercial traffic was allowed to access the tunnel on weekends and holidays. In 2003, with the substantial completion of the I-90 portion of the Big Dig, the tunnel was opened to all traffic at all times.
The tunnel is 8,448 feet (2,575 m) long, of which approximately 3,960 feet (1,210 m) are underwater. A toll of $3.50 is collected in the westbound direction, and the Fast Lane electronic toll collection system is in use. Commercial vehicles, including taxis, pay a toll of $5.25.
