At the edge of Newbury Marshes delineating Newburyport to the south an industrial park provides a wide range of jobs. Newburyport is on a major north-south highway, Interstate 95. The outer circumferential highway of Boston, Interstate 495, passes nearby in Amesbury. A colonial road, the Newburyport Turnpike (U. S. Route 1), still traverses Newburyport on its way north. The commuter rail line to Boston ends in a new station at Newburyport. The earlier Boston and Maine Railroad leading further north was discontinued.
