odd bridge

[Sumpter250]

I would have like to have made these larger, and kept some sharp detail but..... In the upper photo you can clearly see the "steel" support legs.
In the lower photo, the "Stone" support.
Looking at the lower photo I see the same four support pieces, and the transverse I beam, just under the ends of the bridge. I also see that the "corners" of the "stone support" are lined up with the short support pieces above the "stone".
I still strongly suspect that what we're seeing in the lower photo is a decorative covering of the steel legs that hold the bridge up. What's seen in the upper photo is, I believe, the original, uncovered, steel legs.

       

Then again, I don't believe too strongly in alien space craft......on the other hand, if government was involved...............

For the record, whatever bridge style I use for the bridge tender's walkway, it will rest on stone/rock abutments. Even though it is in the lower Kennequogue river, that part of the river is affected by ocean tides, and there is salt water present at least part of the time.
