The Spaulding Turnpike is a toll road in New Hampshire, USA, running 33 miles from Interstate 95 in Portsmouth northwest to Milton. The turnpike roughly parallels the Maine border, and in the mid-1990s New Hampshire Route 16 was resigned onto the turnpike. There are two toll plazas on the turnpike, in Dover and Rochester.
The turnpike is part of the New Hampshire Turnpike System operated by the New Hampshire Department of Transportation Bureau of Turnpikes. Like most turnpikes, it is a 4-lane divided highway. Once it makes it to Rochester, however, it becomes a two-lane freeway, where it merges into one two-lane roadway, while still being limited access, and heads for Milton, where it ends. Route 16 continues as an all access highway. Exit 1 was previously an at-grade crossing with traffic lights, but has since been converted into a diamond interchange.
