 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 .
