Description 

The only single girder fin back bridge in America. It has an unsymmetrical span arrangement of 156, 340 and 190 feet. It was built as a cast in place, pre-stressed, box beam/girder balanced cantilever. This design essentially acts as an inverted haunched girder. It was built to showcase the entrance to the Estates of Barton Creek subdivision. A subdivision of Multi-million dollar houses. The design was chosen to minimize environmental impacts to the Barton Creek Gorge.

This just seems to be this: http://bridgehunter.com/oh/gallia/adamsville/ but with just one girder instead of two

> Also what the heck am I looking at, this bridge confuses me.

There aren't a lot of photos, but what I'm seeing is sort of a single web "solid truss". Yes, "solid" and "truss" are mutually exclusive, but maybe it will help the thought process.

There are two functions.

First is the fins and the center beam make a rigid, load bearing span across space. So those fins are above the beam, so they are under compression - which is a good use for concrete. They are doing pretty much the same thing that a pony or through truss's webs are doing, except these are solid.

The second function is the side-to-side cantilevers that support the deck and transfer the load onto the center beam. This is show by the under-the-deck photos.

Does this help? Or am I answering the wrong question?

As it is asymmetrical, with the demolition of the Nine Span Bridge should this be listed as last of it's kind? Being the last notable Asymmetric bridge in the country.
