Paralleling the railroad tracks, NY 240 winds northwest through Colden as State Road, a two-lane road through dense woods. The woods changeover to wide fields as it winds northwest, passing west of Walter Kummer Town Park before entering the hamlet of Colden. In the hamlet, NY 240 intersects with the termini of CR 222 (Boston–Colden Road) and CR 562 (Heath Road). After this intersection, NY 240 darts several directions while winding northward as a two-lane residential street through the town of Colden. At the junction with CR 400 (Knapp Road), the route changes names to Davis Road before winding northeast into the hamlet of West Falls. Now in the town of Aurora, NY 240 runs along the creek as Davis Road, intersecting with the eastern terminus of CR 372 (Behm Road).
