The Massachusetts Turnpike (commonly shortened to the Mass Pike or The Pike) is the easternmost stretch of Interstate 90. The Turnpike begins at the eastern border of Massachusetts in Boston and connects with the Berkshire Connector portion of the New York State Thruway. The Turnpike traverses the state and serves the major cities of Worcester and Springfield. The highest point on the Turnpike is in the Town of Becket in the Berkshire Hills, at elevation above sea level; this is also the highest point on Interstate 90 east of South Dakota.
