This “easy roadside bench mark” was more of a challenge than we’d expected. It was in an awkward place to reach and to photograph, and we had plenty of thorny branches to clear before we could even get a good look at the mark. The mark is in good condition; however, a new bridge has been built and this old bridge deprecated. I wonder whether its days are numbered.

Was this meant to be a point itself, or is it a reference to LY0754? A view of the bridge from the northwest. The mark is on the near right corner. The orange control point (or reference point) is in the foreground. Looking N from the new bridge toward the old bridge, mark indicated. Looking ENE from the new bridge toward the old.
