Shaw Bridge, also known as Double-Span Whipple Bowstring Truss Bridge, is a historic bridge in Claverack, New York, United States. It carried Van Wyck Lane over Claverack Creek, but is now closed to all traffic, even pedestrians. It is "a structure of outstanding importance to the history of American engineering and transportation technology." Specifically designed by John D. Hutchinson, the bridge employs the basic design of Squire Whipple. It is the only extant "double" Whipple bowstring truss bridge in the U.S., having two identical spans placed in series over a common pier. Read more on Wikipedia
