Description 

One of 4 extant Howe-truss covered bridges in Pennsylvania. It is the longest of these that has not been completely rebuilt. Erected originally to transport cargo from a grist mill, the bridge still carries vehicular traffic through what became McConnell's Mill State Park in 1957. In the late 1950s, a steel support structure was added to the deck and an asphalt covering was tacked onto the roof... -- Historic American Engineering Record (HAER PA-458)
