The Ted Williams Tunnel is a highway tunnel in Boston, Massachusetts. The third in the city to travel under Boston Harbor, with the Sumner Tunnel and the Callahan Tunnel, it carries the final segment of Interstate 90 (the Massachusetts Turnpike) from South Boston towards its eastern terminus at Route 1A in East Boston, slightly beyond Logan International Airport. The tunnel is named after the Boston Red Sox baseball legend Ted Williams.

The underwater section of the tunnel is 90 feet below the surface of Boston Harbor, the deepest such connection in North America. [2]

History

Map showing the Williams tunnel (shown in red)

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

"Fast Lane" system. Vehicles with a Massachusetts E-ZPass transponder pay $1.75, and the tolls are higher for vehicles with an out of state E-ZPass or vehicles without an E-ZPass. Eligible East Boston residents for the E-ZPass discount program pay $0.20 for either direction.[3] Commercial vehicles pay higher, depending on number of axles.[4]

Traffic detoured onto I-93 at the South Bay Interchange after collapse.

On July 10, 2006, at approximately 11 p.m. four three-ton sections of a concrete drop ceiling inside the

Logan Airport
.

Late in the evening of August 8, I-90 connector ramp A leading to the Ted Williams Tunnel was reopened to general traffic, easing the crunch on Logan Airport traffic coming from the south. Cars heading to the airport northbound on the Southeast Expressway (I-93) would get off at exit 15B (former exit 18)[7] and take the South Boston Access (Haul) Road to Ramp A, eliminating the need to go through downtown Boston and U-turn at Storrow Drive to access the Callahan Tunnel.[8] One eastbound lane of the connector tunnel which collapsed was reopened to traffic on September 1.
