While being named "Bridge to Nowhere", it was actually built in advance of the Wabash River bridge that was being planned at Merom, IN. This is my understanding from my grandfather, who helped build this bridge.
It is very still used and very solid to this day. It also has a name plate on the wall of it.
Here's the link to the original story:
