I tried walking down to get a look from the SW today and the undergrowth was too dense for what I was wearing. This one may be easier to get to when the leaves are off.

Switch to Bird's Eye View for a nice shot of this bridge. I'll be up that way this Summer, so I'll try to remember to look for it.

This is a large and impressive open spandrel arch according to Bing maps, but I can't find good photos online anywhere.
