History
When it was built, the circle marked the northern terminus of the New Hampshire Turnpike, later designated as part of Interstate 95, and linked the NH Turnpike with the Spaulding Turnpike to form what the New Hampshire Department of Transportation's Bureau of Turnpikes collectively terms the "Eastern Turnpike".[1] The NH Turnpike has since incorporated the remainder of I-95 in NH to the Piscataqua River Bridge.[2]
