 A short distance later, CR 517 comes to an interchange with the Route 15 freeway.Following this interchange, the route heads northeast and crosses under the New York, Susquehanna and Western Railway's New Jersey Subdivision line and runs immediately to the west of that railroad line as it continues through rural areas with homes.The road intersects CR 620 and becomes Ogdensburg Road as it turns north away from the railroad and crosses into Ogdensburg.
