NY 147 begins at an intersection with NY 5 in the Schenectady County village of Scotia. NY 147 proceeds northeastward as Scandaga Road, a two-lane commercial street past Maple Shade Cemetery and crossing over an Amtrak line. After crossing the tracks, the route enters the town of Glenville, where it connects to County Route 30, which does not directly intersect with NY 147. NY 147 crosses over another railroad line, intersecting with the terminus of CR 47. After ascending up a hill, NY 147 intersects with CR 49. The route remains a residential two-lane highway, entering the hamlets of Harding Crossing and Beukendaal, at which point, intersects with CR 32. Curving northward into the hamlet of Glenville Center, NY 147 intersects with CR 34 and CR 36 before leaving the hamlet. The route remains primarily residential, bending to the northwest a distance from the Saratoga County line. NY 147 enters the hamlet of Lower Corners, where it intersects with the terminus of CR 40. Just north of Lowers Corners, NY 147 intersects with Charlton Road before NY 147 does as well. After crossing into Saratoga County, NY 147 intersects with CR 55 in the town of Charlton. The backdrop becomes rural, entering the hamlet of West Charlton, a small residential part of Charlton. North of West Charlton, NY 147 intersects with NY 67 then crosses into the town of Galway. The road remains rural, passing through the village of Galway, crossing CR 45 in the middle of Galway. NY 147 bends to the northeast out of downtown and continues northward as a two-lane rural highway through Galway, bending northwestward into the hamlet of Kimball Corners. In Kimball Corners, NY 147 intersects with NY 29, which is where the NY 147 designation terminates. The right-of-way continues north as Dean Lung Road.
History
In 1912, the New York State Legislature created Route 37-a, an unsigned legislative route extending from Route 25 in the village of Ballston Spa to Route 37 in the town of Galway by way of Scotch Church and the village of Galway. The portion of Route 37-a between Scotch Church and NY 29 north of Galway village became the northern half of NY 147, a new route extending from Scotia to Galway, as part of the 1930 renumbering of state highways in New York. NY 147 has remained unchanged since that time.
