Cook's Dam Bridge

Art S:

I believe you are in error here. All photos are of the same location, known as "Cook's Dam" up to the present day. The earliest was a wooden covered pony truss (BH 92799) that was replaced in 1872 by an iron bowstring. In 1874 a dam upstream failed and both the bridge and the gravity dam were destroyed. Photo #3 is a stereoscope slide taken 1872-1874 ("similar bridge, different dam.") Photos 1 & 2 are post 1874 and show a different bowstring and an arch dam. All three photos are labeled "Cook's Dam." I didn't make a separate entry for the 1872 bridge since I only located the one picture of it. Incidentally, the bridges crossed Main Street. Spring Street intersects with Main south of the bridge. Sorry for the confusion.

My suspicion is that the single truss line bowsting is a different bridge at a lotion upstream of the curved 'Cook's Dam' at a point called Dam Path. The dam is still present and seems to match.
