Transportation

Each of the New England states has its own Department of Transportation which plans and develops systems for transport, though some transportation authorities operate across state and municipal lines. The Massachusetts Bay Transportation Authority (MBTA) oversees public transportation in the Greater Boston area. It is the largest such agency and operates throughout eastern Massachusetts and into Rhode Island. The MBTA oversees the oldest subway system (the Tremont Street subway) and the second most-used light rail line (the Green Line) in the United States, as well as one of five remaining trolleybus systems nationwide. Coastal Connecticut makes use of the Metropolitan Transportation Authority of New York due to the connection of that region to New York's economy. The MTA operates the Metro-North Railroad in coordination with the Connecticut Department of Transportation. CTrail is a division of the Connecticut Department of Transportation which operates the Shore Line East along its southern coast, terminating in Old Saybrook and New London. It also operates the Hartford Line, leading south to New Haven and north to Springfield. Commuter rail service is provided north of Springfield to Greenfield, Massachusetts, as part of the Valley Flyer Amtrak route.

Amtrak provides interstate rail service throughout New England. Boston is the northern terminus of the Northeast Corridor. The Vermonter connects Vermont to Massachusetts and Connecticut, while the Downeaster links Maine to Boston. The long-distance Lake Shore Limited train has two eastern termini after splitting in Albany, one of which is Boston. This provides rail service on the former Boston and Albany Railroad which runs between its namesake cities. The rest of the Lake Shore Limited continues to New York City.

Bus transportation is available in most urban areas and is governed by regional and local authorities. The Pioneer Valley Transit Authority and the MetroWest Regional Transit Authority are examples of public bus transportation which support more suburban and rural communities.

South Station in Boston is a major center for bus, rail, and light rail lines. Major interstate highways traversing the region include I-95, I-93, I-91, I-89, I-84, and I-90 (the Massachusetts Turnpike). Logan Airport is the busiest transportation hub in the region in terms of number of passengers and total cargo, opened in 1923 and located in East Boston and Winthrop, Massachusetts. It is a hub for Cape Air and Delta Air Lines, and a focus city for JetBlue. It is the 16th busiest airport in the United States. Other airports in the region include Patrick Leahy Burlington International Airport, Bradley International Airport, Rhode Island T. F. Green International Airport, Manchester–Boston Regional Airport, and Portland International Jetport.
