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 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.

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 Battle of Bunker Hill was fought on June 17, 1775, during the siege of Boston in the first stage of the American Revolutionary War. The battle is named after Bunker Hill in Charlestown, Massachusetts, which was peripherally involved. It was the original objective of both the colonial and British troops, though the majority of combat took place on the adjacent hill, which became known as Breed's Hill. On June 13, 1775, the leaders of the colonial forces besieging Boston learned that the British were planning to send troops out from the city to fortify the unoccupied hills surrounding the city, which would give them control of Boston Harbor. In response, 1,200 colonial troops under the co…
