Past Webster, NY 3 followed Ridge Road through Wayne County to Red Creek, where it continued northeast on what is now NY 370 and NY 104A through Red Creek, Fair Haven, and Sterling to western Oswego County. At Southwest Oswego, NY 3 joined the routing of modern NY 104 through Oswego and Mexico to Maple View. Between Maple View and Watertown, NY 3 overlapped NY 2 along what is now US 11. Past Watertown, NY 3 was routed along today's NY 12F and NY 180 to Limerick, where it continued north to Clayton by way of modern NY 12E. East of Clayton, it followed modern NY 12, NY 26 and CR 192 through Alexandria Bay to Redwood. From there, it utilized the current alignment of NY 37 up through Ogdensburg (by way of Main and Ford Streets in the city) before continuing to Waddington on Van Rensselaer Road. NY 3 went east from here along a now-dismantled riverside highway and Town Line Road to Massena, where it was routed on modern NY 37B.
