Sure looks like a bridge to me, right under the red pin. The deck looks overgrown with grass.
Well, a couple of us humans looked, and a couple of us still couldn't see it.
If a human was to look at google earth or maps that human will see that the truss has been kept and is sitting on the ground just south of the new bridge. Hopefully, someone will get curious and go confirm this, but for now, my word has to stand.
A new bridge is shown in satellite imagery, was it relocated somewhere else?
This is the oldest remaining truss bridge in the state of Wyoming. It was not replaced in 2008.
Yeah... I just didn't look hard enough!
