terminus at US 22 in Atlanta. The route was extended to its long-time northern terminus in 1935. No major changes would occur to the route until the route was renumbered to SR 207 in 1962 due to the construction of I-277 in Akron. SR 280 (1930–1962) SR 280 was a state highway that existed from 1930 until 1962 and traveled between Amesville and Trimble. The route remained along this alignment for its entire 32-year history. In 1962, due to the building of I-280 in the Toledo area, all of SR 280 became part of an extension of SR 329 which previously ended at US 50 Alt. in nearby Bern Township. SR 283 (1931) SR 283 was a short-lived designation for a state route near Holland. This designation had replaced SR 223 which had to be renumbered due to the addition of US 223 in the state. Within one year, the route number was changed again, this time to SR 326. SR 288 (1931–1940) SR 288 was the predecessor to SR 640 in Lake County. The route was designated in 1931 on the Willowick–Willoughby route it followed for its entire history. In 1940 for unknown reasons, the route number was changed to SR 640. SR 289 (1931–1937) SR 289 was a short state route entirely in New Haven Township. The route existed from 1931 until 1937 and acted as a connector from SR 61 to the former SR 194. After 1937, the entire route became the northernmost of SR 598 following its extension to Huron County. SR 290 (1932–1962) SR 290 was the state route that became SR 296 in 1962. The route throughout most of its history consisted of a routing starting north of Urbana and traveling east to the community of Middletown within Wayne Township, Champaign County. According to the 1932 official Ohio state highway map, SR 290 traveled along the former SR 275 between West Liberty and Middletown even though prior and successive maps show this segment as SR 275. By 1933, SR 290 was routed from US 68 near Kings Creek to SR 275 in Middletown. In 1937, the route was extended slightly west to end at SR 29 (originally SR 54). After 1962 when Ohio routes that shared numbers with proposed Interstate highways were renumbered, SR 290 became SR 296 because of the proposed Interstate 290 in Cleveland (which later was built as I-490).
