Fort Point Tunnel
The Fort Point Channel Tunnel is a tunnel underneath the South Boston Streets and Fort Point Channel. It was built using a casting basin. It was built 1991–1994 in the Big Dig The Central Artery/Tunnel Project (CA/T Project), commonly known as the Big Dig, was a megaproject in Boston that rerouted the Central Artery of Interstate 93 (I-93), the chief highway through the heart of the city, into the 1.5-mile (2.4&n .... In July 2006, a ceiling tile and associated debris weighing 26 tons collapsed, causing the death of a passenger in a vehicle in the tunnel and severe injury to the driver. This incident and the resulting inspections and repairs delayed the Big Dig construction project by a year. References {{Coord, 42.347, N, 71.054, W, display=title Tunnels in Boston ...

Fort Point Channel
Fort Point Channel is a maritime channel separating South Boston from downtown Boston, Massachusetts, feeding into Boston Harbor. The south part of it has been gradually filled in for use by the South Bay rail yard and several highways (specifically the Central Artery and the Southeast Expressway). At its south end, the channel once widened into South Bay, from which the Roxbury Canal continued southwest where the Massachusetts Avenue Connector is now. The Boston Tea Party occurred at its northern end. The channel is surrounded by the Fort Point neighborhood, which is also named after the same colonial-era fort. The banks of the channel are still busy with activity. South of Summer Street on the west side of the channel is a large United States Postal Service facility. A large parcel, home to Gillette, lies at the southeast corner of the channel. The back of the Federal Reserve Bank of Boston building looks over the channel, and another federal building, the John Joseph M ...

Big Dig
The Central Artery/Tunnel Project (CA/T Project), commonly known as the Big Dig, was a megaproject in Boston that rerouted the Central Artery of Interstate 93 (I-93), the chief highway through the heart of the city, into the 1.5-mile (2.4 km) tunnel named the Thomas P. O'Neill Jr. Tunnel. The project also included the construction of the Ted Williams Tunnel (extending I-90 to Logan International Airport), the Leonard P. Zakim Bunker Hill Memorial Bridge over the Charles River, and the Rose Kennedy Greenway in the space vacated by the previous I-93 elevated roadway. Initially, the plan was also to include a rail connection between Boston's two major train terminals. Planning began in 1982; the construction work was carried out between 1991 and 2006; and the project concluded on December 31, 2007, when the partnership between the program manager and the Massachusetts Turnpike Authority ended. The Big Dig was the most expensive highway project in the United States, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Big Dig Ceiling Collapse
The Big Dig ceiling collapse occurred on July 10, 2006, when a concrete ceiling panel and debris weighing and measuring fell in Boston's Fort Point Channel Tunnel (which connects to the Ted Williams Tunnel). The panel fell on a car traveling on the two-lane ramp connecting northbound I-93 to eastbound I-90 in South Boston, killing a passenger and injuring the driver. Investigation and repair of the collapse caused a section of the Big Dig project to be closed for almost a full year, causing chronic traffic backups. Cause The east ends of the westbound and eastbound connector tunnels were designed and constructed in the same manner. Both ends of the tunnel were built sooner than the connecting section, in order to allow the D Street bridge above to be constructed sooner. The end sections had not been designed to incorporate a hanging ceiling system like that used in the connecting section. The collapse of the ceiling structure began with the simultaneous creep-type failure of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
