Description 

The bridge has been rehabilitated since the photographs at this link http://historicbridges.org/bridges/browser/?bridgebrowser=pe... were taken in July 2006. The stone ends remains, but what remains does not resemble the bridge as it originally looked. The photos taken 5/20/2017 reflect the current state of the bridge.
