The route parallels the track for roughly , over which time it passes to the north of Greenlawn Memorial Park. As the trackage and the highway approach a point known as Amboy Station, NY 173 curves away from the railroad and heads southeast toward Amboy. After making the turn, NY 173 meets Pottery Road (County Route 164 or CR 164), a local road leading to Camillus Airport, a simple one-runway facility located adjacent to the railroad line. NY 173 continues into and through Amboy, passing a large area of tailings that was once the site of the Syracuse Municipal Airport. The brownfields are bordered to the north by Ninemile Creek and to the south by the Old Erie Canal, both of which are traversed by NY 173 on its way into the densely populated Fairmount neighborhood of Camillus.
