Ted Williams Tunnel
tunnel in Boston
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.
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.
This brief starts where responsible research should: with the source description of “Ted Williams Tunnel” as tunnel in Boston. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as tunnel in Boston. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 24, 2026. The linked authority identifier is Q151975. VIAF identifies the subject as 315531527. Authority coordinates are 42.353, -71.028. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1995.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
