This is a list of former state routes in Ohio since 1923 with route numbers from 271 through 352 inclusive. SR 271 (1930–1931) SR 271 was a state route that existed from 1930 until 1931 and was located entirely in Williams County. When it was created, it ran along previously unnumbered roads from the village of Montpelier to Bridgewater Township at US 20. After its two years in existence, the entire route became a part of US 20S. Today, the entire route is a section of SR 576. SR 271 (1932–1962) SR 271 was a state highway through east-central Ohio. When it was first designated in 1932, it ran from Coshocton to North Salem taking over a part of SR 95. In 1935, the route was vastly expanded west to include all of the former SR 309 from Tunnel Hill to Coshocton, unnumbered roads from New Guilford to Tunnel Hill, and part of SR 206 from Martinsburg to New Guilford. The route experienced one more extension, this time at its eastern terminus to act as a spur to the community of Birmingham. No major changes would occur to SR 271 until 1962 when the route was renumbered to SR 541 due to the new Interstate highway, I-271. SR 272 SR 272 was a state highway located north of downtown Canton. The entire route followed Canton's 30th Street and connected SR 8 and US 62/SR 43. The route was in existence from 1930 until 1961, though for its last year as a state route, SR 272 was marked on the official Ohio highway map. After 1961, US 62 was brought onto a new freeway alignment just south of 30th Street. SR 272 was deleted from the system as a result. SR 275 (1930–1962) SR 275 was a state route stretching from Rosewood to just west of Marysville. The first section of SR 275 that was designated was its segment from West Liberty to Marysville at SR 32 (later US 33); it was signed in 1930. In 1937, the route was extended west to SR 29 near Rosewood. After 1962, the SR 275 designation was replaced by SR 245 due to the signing of I-275 near Cincinnati. SR 277 (1930–1962) SR 277 was the predecessor to SR 207 and ran from north of Chillicothe at SR 104 to Mount Sterling. The route when it was created in 1930 originally had its northern
