Evidence: 100 • authority: 72

The Big Dig was a megaproject in Boston that rerouted the elevated Central Artery of Interstate 93 into the O'Neill Tunnel and built the Ted Williams Tunnel to extend Interstate 90 to Logan International Airport. Those two projects were the origin of the official name, the Central Artery/Tunnel Project (CA/T Project). The megaproject constructed the Zakim Bunker Hill Bridge over the Charles River, created the Rose Kennedy Greenway in the space vacated by the previous elevated roadway and funded more than a dozen projects to improve the region's public transportation system. Planning began in 1982 and construction was carried out between 1991 and 2006. The project concluded in December 2007.…

The Charlestown High Bridge (referred to as the John F. Fitzgerald Bridge on old AAA Tourbook maps) spanned the Charles River in Boston, Massachusetts, and was part of I-93/US 1 at the north end of the Central Artery. This double-decked truss bridge, built in 1954, was to originally carry I-95 through Boston from southwest to northeast in tandem with the Tobin Bridge, built in 1950. The I-95 project and several other highway projects in and around Boston, including both the highly controversial Inner Belt (I-695) and the Southwest Corridor, completing the right-of-way intended to bring I-95 into Boston from Providence, Rhode Island, were cancelled due to heavy public opposition in the early…

The Leonard P. Zakim Bunker Hill Memorial Bridge (; also known as "The Zakim") is a cable-stayed bridge completed in 2003 across the Charles River in Boston, Massachusetts. It replaced the Charlestown High Bridge, an older truss bridge constructed in the 1950s. The bridge and connecting tunnel were built as part of the Big Dig, the largest highway construction project in the United States. The bridge's unique styling quickly became an icon for Boston, often featured in the backdrop of national news channels to establish location, and included on tourist souvenirs. The bridge is commonly referred to as the "Zakim Bridge" or "Bunker Hill Bridge" by residents of nearby Charlestown. The Leveret…

The Bill Russell Bridge, officially the William Felton "Bill" Russell Bridge, is located in Boston and spans the Charles River. As the river's easternmost crossing, the bridge connects the neighborhoods of Charlestown and the North End. The bridge carries a portion of the Freedom Trail linking to the USS Constitution and Bunker Hill. To the north of the bridge, Route 99 begins and the street becomes New Rutherford Avenue. The original structure was completed in 1900. Replacement of that bridge started in fall 2018; following several delays, construction was completed in 2025. The new bridge was named in honor of Bill Russell, a notable figure in the history of the Boston Celtics and a recip…

Charles River Bridge v. Warren Bridge. The three leading cases decided during Chief Justice Roger Taney’s first term had all been argued while John Marshall was still serving as chief justice, and all would have been decided differently if Marshall had lived. (Marshall died in 1835; Taney was named chief justice in 1836.) Taney made certain all three were reargued and decided during his first month on the high bench—and he ensured that all three decisions bore his stamp. Charles River Bridge v. Warren Bridge was the most significant of these decisions and represented a clear departure from the Marshall tradition. The case was a contract dispute. Massachusetts had entered into a contract wit…

The Red Blue Connector is a proposed construction project to extend the Massachusetts Bay Transportation Authority (MBTA) Blue Line west to connect to the Red Line, which are the only two MBTA subway lines that lack a direct connection. It would extend the Blue Line 0.4 mi (0.64 km) west beyond the current terminus at Bowdoin station to a new terminus at Charles/MGH station, eliminating the former as a result. The project is suggested to relieve pressure on Downtown Boston stations, overcrowding on the Green Line (which is currently the most convenient way to transfer between the two lines), and to connect communities unlinked by public transit, including Cambridge and East Boston. An under…

The Central Artery (officially the John F. Fitzgerald Expressway) is the concurrent section of Interstate 93, US 1 and Route 3 through Downtown Boston, Massachusetts, United States. The modern-day Artery, built as part of the Big Dig from 1995 until 2003, begins at the Southeast Expressway in the South End. Traveling north, it has an interchange with the east–west Massachusetts Turnpike (I-90), and travels beneath the Financial District and Government Center through the O'Neill Tunnel. Route 3 exits onto the Leverett Connector within the tunnel in Charlestown; US 1 exits aboveground from the Zakim Bridge onto the Tobin Bridge, and I-93 continues on the Northern Expressway toward New Hampshi…
