The underside of this bridge is quite interesting. The bottom chord changes from a battened design to a laced design. This bridge does not have a tremendous amount of lacing, but it has a fair amount for a bridge that was built in 1940. Lacing was being phased out in the decades leading up to the construction of this bridge.

Visited yesterday - very tough to get this all in one frame underneath - a beast

Clark:

Thanks for the clarification. I have edited the KHRI listing to indicate that this is the last remaining example of its type in Kansas. There used to be several examples, but they have been demolished in recent years. The Neosho River used to have quite a population of them.

It's continuous in that there is no break in the load path from one end to the other. Since some of the upper members are in tension cantilever is also correct.

This seems to be the last existing cantilever of this type in KS. It ought to be the focus preservation efforts.

KSHS seems to consider this one to be a continuous through truss. Engineers, what do you think? Is this a true cantilever?
