The 1957 and 1936 quads show the road as a driveway and not at all a former alignment of Paltz Road, so I reclassified it a mystery. "New Paltz" is actually a town to the west.
The 1892 quad shows "Electric R.R." along the alignment that appears on the google map as the "Maybrook Line old alignment". It may be that when the new alignment was made the cut required a bridge to allow farm access. The bridge may have been relocated or it may have built new at the time of the realignment.
According to the photographer, the line was built around 1889, he said he had no information on the bridge itself.
This may have just been a farmers field access bridge as opposed to the old alignment of Paltz Road. On the trail brochure it has a steel bridge used for farmers access, but no photo.
