In the
1930 renumbering of state highways in New York,
NY 35 was extended northeast from Canawaugus (west of the
village of Avon) to
Ontario by way of
Scottsville,
Rochester, and
Walworth. NY 35 entered Rochester on Scottsville Road and followed Genesee and Main streets through the city. At the east end of Main Street, NY 35 turned south and followed Winton Road to Blossom Road. It curved eastward here to follow Blossom Road east to Browncroft Boulevard in
Penfield. At some point between 1934 and 1938, an alternate route of NY 35 along the portion of Browncroft Boulevard between Winton and Blossom Roads was designated NY 35B. for NY 286A on Blossom Road in
Brighton The NY 35 designation remained in place until the early 1940s when it was split into two designations:
NY 383 west of Walworth and
NY 350 from Walworth to Ontario. As part of the change, NY 35B was renumbered to NY 383B. NY 383 itself was altered on January 1, 1949, to end in downtown Rochester. The former routing of NY 383 between East Avenue (
NY 96) in Rochester and NY 350 in Walworth became NY 286 while NY 383B was redesignated as NY 286A. The portion of the
Sea Breeze Expressway between Empire Boulevard (at the time
U.S. Route 104 and now
NY 404) and
Interstate 490 opened to traffic . Both NY 286 and NY 286A were truncated to begin at their interchanges with the expressway. In Wayne County, the routing of NY 286 was altered slightly in the vicinity of the county line. It originally veered onto what is now Knollwood Drive and followed Knollwood Drive and County Line Road to where the latter met Atlantic Avenue. A new roadway was constructed during the mid-1960s that directly connected the two portions of Atlantic Avenue and bypassed County Line Road entirely and became part of a realigned NY 286 by 1968. Browncroft Boulevard was upgraded into a four-lane
divided highway between the Sea Breeze Expressway (NY 47) and Blossom Road during the mid-1960s. Some parts of the highway were upgraded on the spot; others were bypassed As a result of the upgrade, the alignments of NY 286 and NY 286A west of Blossom Road were flipped, placing NY 286 on Browncroft Boulevard and NY 286A on Blossom Road. and replaced with NY 941V, an unsigned
reference route in length.
Reference markers along Blossom Road still read "286A". ==Major intersections==
