Origins and designation The
New York State Legislature created a statewide system of unsigned
legislative routes in 1908, with two of the routes using parts of what is now NY 63. The stretch of NY 63 connecting
Dansville to Hampton Corners in the
town of Mount Morris became part of Route 15, a highway continuing south to
Hornell and north through
Mount Morris to
Caledonia. Farther north, the piece between
Medina and
Ridgeway was designated as part of Route 30, a cross-state route running from
Niagara Falls to
Rouses Point. Route 30 originally followed current
NY 31 to
Rochester; however, it was realigned on March 1, 1921, to use
Ridge Road instead, bypassing the Medina–Ridgeway highway. In the mid-1920s, three sections of modern NY 63 received posted route numbers for the first time. From Wayland to Dansville, the road was the westernmost part of
NY 52. What is now NY 63 was unnumbered from Dansville northwest to Hampton Corners, where
NY 36 entered from the west on current
NY 408 and followed the path of NY 63 to
Geneseo. The road was unnumbered again until
Pavilion, at which point
NY 62 joined from the south and utilized all of current NY 63 and CR 63-1 to reach the Lake Ontario shoreline in Yates. By 1926, all numbered portions of current NY 63 were state-maintained, as were the unnumbered parts from Geneseo to Piffard and from
Groveland to Hampton Corners. and continued south on Old State Road and west on Allegany County's
CR 16 to
NY 19 west of the village of
Angelica. NY 63
overlapped NY 19 south to Belvidere, where NY 63 turned onto modern
CR 20. It continued west on CR 20 and
NY 446 through
Cuba to a junction with
NY 16 in
Hinsdale, where it ended. North of Pavilion, NY 63 followed modern
NY 19 to the
Lake Ontario shoreline in
Hamlin. NY 63 was altered again in December 1940 to follow the former routing of NY 36A south from Mount Morris to Dansville, from where it continued east to Wayland by way of an overlap with NY 245. NY 245 was truncated northeastward to
Naples and NY 63 was cut back to NY 36 in Dansville around the same time, leaving the Dansville–Wayland highway as an unsigned
reference route. This was partially reversed in the late 1970s or early 1980s when NY 63 was reextended to Wayland. On April 1, 1989, ownership and maintenance of Lyndonville Road north of NY 18 was transferred from the state of
New York to
Orleans County as part of a highway maintenance swap between the two levels of government. NY 63 was truncated to end at its junction with NY 18 while its former routing to the lake became CR 63-1. In the mid-2000s, the route was reconfigured in the northern part of Medina to use Main and Commercial streets instead of Center Street and Prospect Avenue. The change was made as part of a village project known as the Pass Thru Project, and the realignment eliminated a three-block overlap with the easternmost part of
NY 31E on Center Street. The most publicized and perhaps most fought-over possibility mentioned was that of a new expressway from Mount Morris to Pembroke, bypassing these three routes. The
Wyoming County Chamber of Commerce was a driving force behind this, hoping interchanges in
Perry,
Warsaw and
Attica would promote business growth. While residents along the NY 63 corridor are against the increased truck traffic along the corridor (spurred by the
North American Free Trade Agreement), most of those same residents, along with other groups, also fought the proposed expressway. The general consensus of all of these groups is that NYSDOT should impose restrictions on the NY 63 corridor and force trucks to remain on I-390 and the Thruway to travel between
Buffalo and
Pennsylvania. ==NY 63A==
