Input: Question: What county is Gallupville part of? Passage:The path of modern NY 85 west of Slingerlands roughly follows that of the Albany, Rensselaerville, and Schoharie Plank Road, a plank road established to connect the city of Albany with the town of Schoharie by way of passing through Rensselaerville. The Albany, Schoharie, and Rensselaerville Plank Road Company was organized on October 10, 1849, with Lansing Pruyn as president. On March 25, 1850, the company was given a 30-year charter; and the road from Lydius Street in Albany (today Madison Avenue) to the hamlet of New Salem—now New Scotland Avenue in the city of Albany and New Scotland Road in Bethlehem and New Scotland—and the portion of the road from Bernville to Gallupville were planked with wooden boards. Portions of the plank road were already long established roads, such as the Beaverdam (or Beaver Dam) Road in western Albany County near New Salem, which had already existed for quite some time prior to moving to an easier grade around New Salem in 1806. The plank road/turnpike spurred the development of many places along its path, such as a hotel at what would evolve into the hamlet of Hurstville and a post office at what would become the hamlet of Slingerlands.
