The mirrored knee bracing on the portals and struts was commonly used by the Horseheads Bridge Company during the 1890's.

Interesting, a span separated by the island in the creek. Looks to be shorter in height than the through span with the Whipple, but rather long.

Yep, the second postcard does indeed show a third span. Interesting.

Yup Michael... It's a Pratt through. This was probably originally a 2-span Bowstring and one of the spans was compromised in some way and replaced by the Pratt.

looks like a Whipple Bowstring and a regular Pratt truss.

It'd be pretty cool to find the two different Whipple types together though :)

Looks like a Whipple Bowstring to me - not to be confused with a Whipple truss.

Squire Whipple invented his own Bowstring design, which inspired other bridge companies to create their own patented Bowstrings.

He also created the double - intersectional Pratt truss which became known as the Whipple truss.

Thus, Squire Whipple ended up having two completely different types of bridges named after him. This often confused those who are trying to learn truss terminology.

2 Whipples or just one?
