New York State Route 18 - Suffixed Routes

Suffixed Routes

NY 18 has had seven suffixed routes using six designations; only one, NY 18F, still exists. Most of the routes were renumbered when NY 18 was truncated to Lewiston c. 1962.

• NY 18A was an alternate route of NY 18 between Collins and Hamburg. It was assigned c. 1931 and mostly replaced with an extended NY 75 c. 1962.
• NY 18B was an alternate route of NY 18 through the eastern suburbs of Buffalo. It was assigned c. 1935 and mostly replaced with an extended NY 277 c. 1962.
• NY 18C was a short-lived alternate route of NY 18 through the eastern Buffalo suburbs. It was assigned c. 1932 and began at NY 18 (now US 62) at Big Tree in Hamburg and followed Big Tree Road and modern US 20 to NY 35 (now US 20 and NY 130) in Depew. The Transit Road portion of the route overlapped with NY 78. NY 18C was truncated to consist only of the Transit Road portion c. 1935 and removed entirely c. 1938 as part of US 20's realignment through western New York.
• NY 18D was a spur route linking NY 18 to the Whirlpool Rapids Bridge north of downtown Niagara Falls. It was assigned c. 1932 and renumbered to NY 182 c. 1962.
• NY 18E was a short spur assigned in the early 1930s to a connector between then-NY 18 (now NY 18F) and the original Queenston–Lewiston Bridge in Lewiston. It was removed in the early 1960s when the original bridge to Queenston was replaced with the modern Lewiston–Queenston Bridge a short distance upstream.
• The NY 18F designation has been used for two distinct highways:
  • The first NY 18F was assigned c. 1934 to NY 18's original routing between Cattaraugus and Little Valley. The designation was removed c. 1938.
  • The current NY 18F (9.80 miles or 15.77 kilometres) is an alternate route of NY 18 in western Niagara County that serves the riverside villages of Lewiston and Youngstown. It was assigned in 1949.
