New York State Route 12 - Suffixed Routes

Suffixed Routes

NY 12 has had seven suffixed routes bearing six different designations. Two have since been removed and at least partially renumbered. All of the routes were assigned as part of the 1930 renumbering of state highways in New York unless otherwise noted.

• The NY 12A designation has been used for two distinct highways:
  • The first NY 12A was an alternate route of NY 12 between Sherburne and Utica. It was assigned in the late 1920s and renumbered to NY 12B in the 1930 renumbering of state highways in New York.
  • The current NY 12A (0.98 miles or 1.58 kilometres) is an east–west spur connecting NY 12 to I-88 and NY 7 on the banks of the Chenango River in Chenango Bridge, Broome County. The entire route is known as Chenango Bridge Road and is one of only six signed New York state highways less than a mile in length. The route was assigned in the early 1930s.
• NY 12B (33.57 miles or 54.03 kilometres) is an alternate route of NY 12 between Sherburne and Utica.
• NY 12C is a former alternate route of NY 12 between Utica and Barneveld. The route was eliminated in 1970, at which time the lone portion of NY 12C that did not overlap another state route was redesignated as NY 291.
• NY 12D (11.50 miles or 18.51 kilometres) is an alternate route of NY 12 between Boonville and Lyons Falls.
• NY 12E (39.76 miles or 63.99 kilometres) is an alternate route of NY 12 between Watertown and Clayton. While NY 12 follows a direct path between the two locations, NY 12E veers to the west to serve communities along Lake Ontario and the St. Lawrence River.
• NY 12F (6.89 miles or 11.09 kilometres) is a spur connecting NY 12 in downtown Watertown to NY 180 near the Watertown International Airport in Dexter.
