The Cunningham Bridge was a historic bridge previously listed on the National Register in Adams County, Pennsylvania, near Greenmount, Pennsylvania, United States. The three-section iron bridge spanned west-to-east from Franklin Township to Cumberland Township and was, at the time of its demolition, among the oldest examples of a Baltimore truss.
It was listed on the National Register of Historic Places as "Bridge in Cumberland Township" in 1988 despite being in Franklin Township, Adams County, Pennsylvania. ()
The bridge was permanently closed to traffic in June 2005 due to structural degradation and safety concerns. Despite efforts by the Adams County Commissioners to preserve it, the bridge was eventually demolished in 2013 and subsequently replaced.
