Cambria Center to Lockport. From Middleport to Medina, however, Route 20 was routed on modern NY 31 instead. East of Rochester, the section of Route 20 between Fairport and Macedon was reconfigured to utilize what is now NY 250 and NY 31. Assignment The first set of posted routes in New York were assigned in 1924. At this time, all of legislative Route 20 west of Rochester became part of NY 3, a cross-state route that began in North Tonawanda and ended in Plattsburgh. By 1926, NY 31 was assigned to an alignment extending from Niagara Falls to Oneida. The route began at NY 34 (now NY 104) in Niagara Falls and followed College Avenue east to the city line, from where it continued eastward to Rochester on the alignment of legislative Route 30. Within the city of Rochester, NY 31 continued east on Ridge Road to Lake Avenue, where it turned south to enter downtown Rochester, becoming State Street at Lyell Avenue. At East Main Street, NY 31 resumed its eastward alignment, crossing the Genesee River and continuing on Main Street to Monroe Avenue, which, at the time, connected directly with Main Street. NY 31 turned right on Monroe Avenue, rejoining its present alignment of NY 31 near Union Street. East of Rochester, NY 31 continued eastward to Jordan, utilizing the Rochester–Pittsford portion of legislative Route 14, the Perinton–Jordan segment of Route 20, and its current alignment between Pittsford and Perinton. From Weedsport to Jordan, NY 31 used a slightly different routing. It initially exited the village on Clinton Road and followed that road to Jordan, where NY 31 turned north and followed modern NY 317 and NY 31 north and east to modern CR 84. NY 31 turned north here, using what is now Old Route 31, current NY 31, and Downer Street to reach Baldwinsville. Within the village, NY 31 followed Downer Street and what is now NY 48 along Syracuse Street between Downer and Genesee Streets. Outside of Baldwinsville, NY 31 remained on its current routing to Cicero, where it followed a more northerly alignment along Lakeshore Road. It rejoined its modern alignment near the eastern town line, and followed it east to what is now NY 316 in Lenox. From here, NY 31 went southeastward to NY 5 in Oneida by way of modern NY 316 and NY 46. Truncations and extensions In the late
