The Spaulding Turnpike is a 33.26-mile (53.53 km) controlled-access toll road in eastern New Hampshire. Its entire length is overlapped by New Hampshire Route 16 (NH 16). Its southern terminus is at the Portsmouth Traffic Circle (I-95/US 1 Byp.) in Portsmouth, a terminus it shares with US 4 and NH 16. Its northern terminus is at an interchange with NH 125 in Milton, where NH 16 continues north as a two-lane freeway.
The turnpike roughly parallels the Maine border. NH 16 was signed onto the Turnpike in the mid-1990s.
The turnpike is part of the New Hampshire Turnpike System operated by the New Hampshire Department of Transportation Bureau of Turnpikes. Along with I-95 between the Massachusetts state border and the Portsmouth Circle (Blue Star Turnpike), the two turnpikes are collectively known as the Eastern Turnpike.
