In Yates County, NY 54 enters the town of Barrington, where Keuka Village Road soon merges in. NY 54 continues north as East Lake Road, paralleling the lakeside as a two-lane residential street before forking northward as a two-lane rural roadway. A second East Lake Road serves as the local residential highway for a short distance, until the hamlet of Crosby. In Crosby, NY 54 becomes a two-lane residential street until the intersection with Gray Road. There, East Lake Road continues a new parallel once again. A short distance later, NY 54 crosses the town line from Barrington into Milo. At the town line, the western East Lake Road changes name to Lower East Lake Road, continuing its lakeside parallel of NY 54. Entering the hamlet of Willow Grove, this merges into NY 54 once again, which soon intersects with the western terminus of CR 30 (Second Milo Road).
