1921, Route 16 was truncated to end at Route 6 (modern NY 5) in Le Roy as part of a partial renumbering of New York's legislative route system. The portion of former Route 16 north of Caledonia became part of Route 15. The section of Route 15 between Scottsville and Chili became part of NY 251, a new route stretching from NY 33 in Gates to then-NY 15 in Victor, in the 1930 renumbering of state highways in New York. NY 386, meanwhile, was assigned by the following year to the portion of Elmgrove Road between NY 31 in Gates and U.S. Route 104 (now NY 104) in Greece. NY 251 was truncated to its present terminus in Scottsville on July 1, 1977, at which time NY 386 was extended south along the former routing of NY 251 to Scottsville. Reference markers for NY 251 are still posted along its former routing. NY 386 utilized a previously unnumbered portion of Elmgrove Road between NY 31 and NY 33 to reach NY 251's former alignment. This part of NY 386 is maintained by Monroe County as the unsigned County Route 158 (CR 158). In 2007, ownership and maintenance of the remainder of the Elmgrove Road portion of NY 386 and the section of NY 386 between NY 33 and NY 33A were transferred from the state of New York to Monroe County as part of a highway maintenance swap between the two levels of government. A bill (S4856, 2007) to enact the swap was introduced in the New York State Senate on April 23 and passed by both the Senate and the New York State Assembly on June 20. The act was signed into law by Governor Eliot Spitzer on August 28. Under the terms of the act, it took effect 90 days after it was signed into law; thus, the maintenance swap officially took place on November 26, 2007. As a result of the swap, all of NY 386 north of NY 33A—except for the section that overlaps NY 33—is overlapped by unsigned county routes. The portion of NY 386 on Chili Center–Coldwater Road is co-designated as CR 256. Along Westside Drive, NY 386 is part of CR 119, the designation for all of Westside Drive. The Coldwater Road segment, meanwhile, is also CR 198 while CR 158 was extended north to cover all of Elmgrove Road. Major intersections See
