causeway, entering the hamlet of Edwardsville on the opposite shore. Upon entering Edwardsville, NY 58 is now in the town of Morristown, intersecting with CR 6 (Black Lake Road). Continuing northwest from CR 6, NY 58 proceeds away from Black Lake as a two-lane rural roadway, crossing several local roads. NY 58 soon enters the hamlet and former village of Morristown, where it intersects with NY 37 (the Seaway Trail). This intersection serves as the northern terminus of NY 58, exactly north of the intersection with NY 3 in Fine. The right-of-way continues north into the hamlet as Main Street towards the St. Lawrence River. History The entirety of NY 58 was assigned as part of the 1930 renumbering of state highways in New York. At the time, NY 58 directly served the hamlets of Edwards and Fullerville. It was realigned to bypass Fullerville to the north and Edwards to the southwest in the mid-1960s.
