The Bridges of Keeseville consist of three historic bridges located in Keeseville, New York, spanning the Ausable River. These bridges include a stone arch bridge constructed in 1843, a wrought iron Pratt truss bridge (1878) and a twisted wire cable suspension footbridge built in 1888. These three bridges represent the evolution of 19th-century bridge design, and together were designated a National Historic Civil Engineering Landmark by the American Society of Civil Engineers in 1987.[1]
The 1878 iron truss bridge (also known as "Upper Bridge") sits on the Essex-Clinton county line, located south of the Keeseville village center. In 2008 it was closed, and is in need of repairs.[2]
A fourth non-historic bridge can be found northeast of these bridges. This bridge carries US 9/NY 22 over the Ausable River just before NY 22 leaves the overlap with US 9 at the northern terminus of NY 9N.
