The Sparkill Creek Drawbridge is a historic Pratt Pony Truss drawbridge located at Piermont in Rockland County, New York. It was built in 1880 by the King Iron Bridge Company of Cleveland, Ohio, and is a single-leaf movable metal bridge. Chains can lift the bridge when an operator turns a crank, helped by counterweights. It spans Sparkill Creek, a tributary of the Hudson River. See also: Read more on Wikipedia
