New York Route 10 is often said to be the last paved state highway in New York when the Glen Harris Highway was paved north of Arietta up through Piseco Lake in the early 1980s.

Due to constitutional constraints relating to the road running through forest preserve, with few exceptions, almost all of modern asphalt road follows the path of the dirt road, although during construction they did bank the curves and widen the road slightly from the horse and buggy road that existed in almost the same form since the 1800s.

I have the 1904 topographic maps of the area too but due to issues with the original map survey, the overlay is more difficult to do accurately compared to the more modern 1954 survey. 

The modern alignment is shown in orange while the topographic map below is from 1954.
