The US Post Office Garage was a historic vehicle maintenance facility at 135 A Street in the South Boston neighborhood of Boston, Massachusetts. The two story building was designed in the International Style by Gilbert Underwood and completed in 1941 by a construction team headed by John Volpe. It was built out of reinforced concrete and steel. Its exterior was scored in a way to give the appearance of paneling, and had large expanses of steel sash windows that typified the International style. Its rounded corners gave it a streamlined appearance.The building was listed on the National Register of Historic Places in 1986. It has since been demolished.

The South Bay Interchange is a massive interchange in downtown Boston, Massachusetts, in the US. The interchange consists of Interstate 90, the Mass Pike Extension, and the Interstate 93 concurrency with US 1 and MA 3 south of the Thomas P. O'Neill Jr. Tunnel.The interchange dominates the South Bay parcel, a 10-acre (40,000 m²) site between Chinatown and the Leather District. It is roughly bounded by Kneeland Street, Hudson Street, the Massachusetts Turnpike mainline, and the Interstate 93 mainline. Currently owned by the Massachusetts Turnpike Authority (MTA), the area is taken up by a major highway interchange between 90, 93, and local streets. There were original plans to re-develop the area with a 600-foot tall office tower, but no such project has taken place.

Widett Circle is a locale in Boston, Massachusetts that has long been used as a wholesale food market, but which has been proposed for several redevelopment projects. It is located between a bend in Interstate 93 and the MBTA rail yards, near the Massachusetts Avenue connector to I-93. Widett Circle was named for Attorney Harold Widett who was the Attorney for the meat packers union. Potential uses for the site include: an additional rail layover for the Massachusetts Bay Transportation Authority (MBTA) a trash recycling and transfer facility a new 28,000-seat stadium for the New England Revolution soccer team, though the team's owners are reportedly focusing on a parcel just north of the circle. a floodable watershedThe current occupants have expressed concern that eminent domain proceedings might be used to take their businesses for other uses.

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.In 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.

The Dewey Square Tunnel in Boston, Massachusetts, is part of Interstate 93 (concurrent with US 1 and Route 3), running under the heart of the city's financial district, including Dewey Square. Built in 1959, it was part of Boston's Central Artery freeway construction project of the 1950s. Known to locals as the South Station Tunnel (due to its proximity to South Station), the Dewey Square Tunnel is of cut-and-cover design, and originally was six lanes wide (three in each direction), with no breakdown lanes. Because of public outcry during construction of The Central Artery, elevated for most of its length and reviled because it cut off views of and access to Boston's historic waterfront, it was decided by then-Governor John A. Volpe that the final section of the artery was to be put underground from just south of Congress Street to Kneeland Street near Boston's Chinatown section. At the time of its construction, it was the widest vehicular tunnel in the world. At one time, a bus terminal serving Peter Pan, Bonanza, and other regional bus lines sat atop the tunnel near its northern portal. The bus station has since been relocated to the major intermodal transportation hub at South Station. The lack of breakdown lanes, the limited number of travel lanes, and the myriad access ramps to and from the Artery and the tunnel caused massive traffic jams and gridlock, forcing transportation officials to consider rebuilding the Artery and putting it totally underground. The Dewey Square Tunnel received new life as part of the massive Big Dig project of the late 1990s and early 2000s. The tunnel was rehabilitated and now serves as exclusive southbound lanes of Interstate 93, complete with a new ventilation system and gently banked corners consistent with appropriate superelevation. Its old northern portal at Congress Street was connected to the underground southbound lanes of the new artery in 2005. A long-closed northbound off-ramp to Chinatown was rebuilt and reopened as a southbound on-ramp from Surface Road. The refurbished tunnel, with 6 lanes at its widest point, was fully opened on March 5, 2005. The Dewey Square Tunnel is the only remaining section of the original Central Artery still in use. Since the completion of the Big Dig project, the name "Dewey Square (South Station) Tunnel" has fallen into general disuse; instead, it is considered to be part of the Thomas P. O'Neill Jr. Tunnel, a name used for the entire length of the north–south tunnel system.

The D Street projects, built in 1949 as the West Broadway Housing Development, are a housing project located in South Boston, Massachusetts. The D Street projects stretch 4 city blocks from West Broadway to West Seventh street and 3 city blocks from B street to D street, forming a perfect square. The land for the West Broadway Housing Development was cleared in 1941, and the project opened in 1949 with 972 units intended for white veteran families only. In 1962, upon receipt of a lawsuit filed by a civil rights group, the Boston city government under Mayor John F. Collins (1960–1968) desegregated the project. It was the first state development under Chapter 200 of the Massachusetts legislature's Acts and Resolves of 1948 to open and the only one built on a slum clearance site, having originally been planned as a privately financed project in 1934.It was one of the Boston projects which remained predominantly white well into the 1990s, despite a largely non-white waiting list for public housing. By the early 1980s, it was one of the most troubled projects in the city, and when Lewis "Harry" Spence was appointed receiver of the Boston Housing Authority, was chosen as one of the three demonstration projects for renovations. The plan, which won urban design awards, involved breaking up the 27-acre development into seven "villages" containing 675 apartments, reintroducing the street grid and replacing the original landscaping with courtyard spaces, and transforming the architecture by adding design elements such as pitched roofs, at a total estimated cost of over $60 million. Although the project is in a rough neighborhood, South Boston was rapidly gentrifying, and in 2000 the remaining quarter of the housing was instead turned over to redevelopment for mixed-income housing and businesses.

South Bay Tower, also known as the Gateway Center, is a proposed skyscraper planned for Boston, Massachusetts. If completed, South Bay Tower would stand as the tallest building in Boston, Massachusetts, and New England, surpassing the 60-story John Hancock Tower by 7 stories and at least 10 feet (3.0 m). The South Bay tower would be built on 10 acres (40,000 m2) of land off Hudson Street just south of Downtown Boston, in an area of Chinatown reclaimed following the conclusion of the Big Dig.The site has come under renewed interest as of February 2016 as the State government considers selling it to developers with the potential for another massive proposal (1.5-2 million sq. ft.) that would involve the relocation of existing Department of Transportation facilities and the reconstruction of Veolia's energy plant.
