The Glen Gardner Pony Pratt Truss Bridge is a historic pony Pratt truss bridge on School Street (formerly Mill Street) crossing the Spruce Run in Glen Gardner of Hunterdon County, New Jersey. It was designed by Francis C. Lowthorp and built in 1870 by William Cowin of Lambertville, New Jersey.[3] The bridge was added to the National Register of Historic Places on September 22, 1977 for its significance in engineering, industry and transportation. It is one of the few early examples of iron Pratt truss bridges remaining in the United States.[4] It was later documented by the Historic American Engineering Record in 1991.[5]
