Blue Point Bridge
The Decatur Herald: July 27 1966

Art, thanks. I definitely need a Bridge Hunting 101 course.
If you stay with it, and you get a sense for how the various designs work, you'll start seeing how each maker solved the design issues and details before standardization. It's almost like an artist's signature style.
Here is a bridge with similar characteristics: http://bridgehunter.com/oh/putnam/6931928/
In my opinion, CBW made particularly elegant and usually ethereal bridges. A particularly nice example is Peevy Road Bridge: http://bridgehunter.com/pa/montgomery/467046040002310/
Gallman is pretty as well: http://bridgehunter.com/oh/licking/gallman-road/
This little bowstring is the only CBW built bridge still existing in IL that is listed on Bridgehunter: http://bridgehunter.com/il/adams/bh53514/
Art, it amazes me you can tell that from this photo. I'll read the article Nathan wrote too.
I am not certain it is. However, there are clues in the design, The vertical elements are single, rolled, beams while other elements indicate an early pin connected truss. David Morrison (the company's founder) was quite creative and innovative. He used these rolled beams instead of built up beams decades before others did. The designs tend to be simple slender and elegant.
Nathan has a nice write-up about the company on his site. I blame him for getting me hooked on them :^)
Thanks to whomever mapped this
How do you know it's CBW ?
Ooooh! CBW? (Columbia Bridge Works?)
I could not find a West Fayette road so I left the location open.
