The Spaulding Turnpike segment of the Turnpike System, including the 11.2-mile Spaulding Turnpike extension, extends from Portsmouth to Exit 18 in Milton. It is 33.2 miles in length and is the major north-south artery in the eastern corridor of the state. This segment of the Turnpike System connects the Blue Star Turnpike (I-95) to NH 16 (the major roadway to northern New Hampshire in the eastern portion of the state), and it connects the major cities of eastern New Hampshire (Portsmouth, Dover and Rochester) as well as several major highways (US 4, NH 16, NH 125, and I-95). It has two toll plazas located at Dover and Rochester, with a maintenance facility for the Spaulding Turnpike located at Dover. Maintenance on the Spaulding Turnpike extension is provided by the Department of Transportation's Bureau of Highway Maintenance and is billed to the Bureau of Turnpikes. In addition, for the convenience of northbound Turnpike System patrons, a rest area with rest rooms and picnic facilities is provided at Hilton Park in Dover, New Hampshire.
