The Massachusetts Turnpike (locally called the Mass Pike or the Pike) is a toll road in Massachusetts, maintained by the Massachusetts Department of Transportation (MassDOT). Spanning 138 miles (222 km), the highway constitutes the easternmost portion of Interstate 90 (I-90); it begins near Logan International Airport at the eastern border of Boston and becomes part of the New York State Thruway at the Berkshire Connector in Canaan, New York, where I-90 continues towards its western terminus in Seattle, Washington. The turnpike traverses the state, and connects Boston with the major cities of Springfield and Worcester.

Construction of the Massachusetts Turnpike began in 1955, and was opened in 1957. It originally travelled from the western border of Massachusetts, near Route 102, across the state until its interchange with Route 128 (now concurrent with I-95) in Weston. The turnpike became part of the Interstate Highway System with its designation as I-90 in 1959; it was lengthened through Allston in 1962, and extended through downtown Boston via the Central Artery in 1965. The Big Dig provided for the creation of the Ted Williams Tunnel, which carries the highway towards its current terminus at Route 1A near Logan International Airport; construction of the tunnel began in 1991, and was opened to the general public in 2003.
