Route 2A exists in several sections of Massachusetts, mainly as parts of former Route 2 that have been moved or upgraded. Route 2A runs from Greenfield in the west to Boston in the east. Route 2A used to extend all the way to Shelburne Falls in Buckland in the west, but as of 2007, the route now terminates at Interstate 91 in Greenfield.Route 2A begins at the rotary intersection of Route 2 at Interstate 91 in Greenfield. It passes through downtown Greenfield before reconnecting to its parent route just west of the Greenfield-Gill town line. After a 12.6-mile silent concurrency, Route 2A leaves its parent road once more, passing through Orange and Athol.
