 The portion of Redman Road north of modern NY 360 in Hamlin was a state highway as early as 1920; however, it was not assigned a designation until the early 1940s, when it became NY 215. At the time, it was the primary highway to and from Hamlin Beach State Park on the Lake Ontario shoreline, as no continuous east – west lakeside roadway existed at the time. This changed in the late 1940s and early 1950s following the construction of the Lake Ontario State Parkway, a lakeshore highway connecting the park to NY 261 in Greece. The parkway began east of NY 215 at Moscow Road and provided a direct connection to Hamlin Beach State Park from Greece, and eventually Rochester. As a result, NY 215 became merely an alternate route to the park.
