The Hancock-Greenfield Bridge is a historic covered bridge carrying Forest Road over the Contoocook River at the town line between Hancock and Greenfield, New Hampshire. The New Hampshire Department of Transportation covered bridge database refers to it as County Bridge. It is a single-span Teco-Pratt timber truss, 88 feet (27 m) long and 27 feet 2 inches (8.28 m) wide, with an internal clearance of 14 feet (4.3 m). The road bed is 20 feet (6.1 m) wide, and carries two lanes of traffic. The bridge's roof is sheathed in asphalt, and its walls are finished in vertical board siding. Built in 1937, it is the first wooden covered bridge in the northeastern United States to use modern engineering techniques (the Teco truss).
