Originally a toll road, New Hampshire’s first turnpike stretched 36 miles, from the Piscataqua Bridge in Durham to the Merrimack River in East Concord.
It was the first of more than 80 turnpikes built in the state by private corporations during the 19th century.
As part of our occasional series, Marking History, NHPR’s Michael Brindley travels to Route 4 in Northwood, where there’s a historical marker paying tribute to the state’s transportation milestone.
