the segment of post-1921 Route 15 from Mumford to Scottsville and the Main Street portion of pre-1921 Route 15 were designated as part of NY 253. NY 35 was truncated and slightly rerouted after US 20 was moved onto its current alignment through Western New York. Instead of continuing south from Scottsville, NY 35 was altered to head west from the village to Mumford, replacing NY 253. The portion of River Road from Scottsville to Quaker Road in Wheatland remained part of NY 251, which had overlapped NY 35 along this stretch. The NY 35 designation was split into two designations in the early 1940s. From Mumford to Ontario Center Road in Walworth, NY 35 was renumbered to NY 383. The remainder of the route in Walworth and Ontario became an extension of NY 350, which had previously ended at a junction with then-NY 33B north of Macedon. The NY 35 designation was then transferred to a highway in Westchester County. The segment of River Road between NY 251 and the Monroe–Livingston county line, vacated by NY 35 , remains state-maintained to this day as NY 940H, an unsigned reference route in length. Suffixed routes NY 35 had two suffixed routes. Both have since been removed from the state highway system or redesignated. NY 35A was a spur route of NY 35 in Buffalo and Cheektowaga. When it was originally assigned as part of the 1930 renumbering of state highways in New York, it began at the junction of Broadway (NY 35) and Bailey Avenue in Buffalo and followed Bailey Avenue north to Walden Avenue, where it turned east and used Walden Avenue and Dale Road to return to NY 35 at a junction midway between the communities of Sloan and Forks. By 1935, NY 18 was rerouted through Buffalo to bypass downtown on Bailey Avenue, resulting in the truncation of NY 35A to the junction of Walden and Bailey Avenues. It was removed completely . NY 35B was an alternate route of NY 35 assigned to Browncroft Boulevard in Rochester. It began at NY 35 and NY 47 in eastern Rochester and ended at NY 35 in Penfield. The route was assigned at some point between 1934 and 1938 and redesignated as NY 383B in the early 1940s to match the renumbering of NY 35. Most of the route east of the city limits is now part of NY
