Hunterdon County has a wealth of historic bridges, presumably due to the number of stream crossings, the success of agriculture, and the materials available to construct the bridges. Over several dozen metal truss bridges, mostly from the 19th century, have been determined by the NJ Historic Preservation Office to be eligible for the National Register of Historic Places.
Additionally, there are over 100 extant stone arch bridges in the County, the largest concentration of stone arch bridges in the entire country - according to a bridge preservation consultant. Many of these stone arch bridges have been deemed either eligible or potentially eligible for the State and National Registers of Historic Places.
