| Route: | 354 |
| Location: | New Garden–Lisbon |
| Formed: | 1934 |
| Deleted: | 1938 |
SR 354 was a state route through central Columbiana County. The route primarily provided access to Guilford Lake to nearby routes. In 1932, an unnumbered state route was created starting near the lake and traveling southeast on mostly dirt roads to US 30 west of Lisbon. The route received its number of SR 354 by 1934. Within one year, it was extended west to the community of New Garden at SR 9. The route existed in this form until 1939 when the entire route became an extension of SR 172, the number the road carries today.
See main article: Ohio State Route 355. SR 355 was a short state route in Eaton, Preble County that served the Fort St. Clair State Memorial. The route was created in 1934 when a formerly unnumbered state route received its number. At a length of 1.37miles, the route began at SR 122 west of downtown Eaton, traveled south to the memorial's entrance, went through the site, and ended at itself.[1] The route was removed from the state highway system in the late 1990s after the memorial's jurisdiction was transferred to the city.

SR 359 was a 1miles state route connecting the entrance of Kendall State Park to SR 8, entirely in Boston Township, Summit County.[2] The route was signed in 1934 replacing an unnumbered state-maintained dirt road. The route would not undergo any changes until the mid 1980s when SR 8 was moved off its surface road onto a nearby freeway. The route stopped appearing in the official state map beginning in 1987 but was included within the 1988 Summit County traffic survey report.[2] The entire route is now a part of Summit County Road 187.[3]

SR 375 was a state route in and in the vicinity of Marietta that existed from 1935 until 1969. The route started at the intersection of Putnam and 3rd Streets; the latter street also carried US 21, US 50 Alternate, and SR 7. The route traveled north out of the city climbing to ridge lines along the hills here. Along its path, it intersected the former state highways SR 326 and SR 351. The route would remain near the tops of these hills except as it approached its northern terminus; the route made several sharp curves to quickly descend a hill to end at US 21.[4] The route was deleted after 1969 which was also around the time I-77 was completed in the city. Today, the parts of the former SR 375 outside of the Marietta city limits are Washington County Road 375.[5]

By 1941, SR 384 was extended east through southern Williams County and northwestern Henry County to end at US 6 near Ridgeville Corners. The route was truncated at its western end to the SR 2 intersection in 1948 since US 6 was rerouted onto the now former section of SR 384. SR 384 would remain on this alignment for the remainder of its time as a state route. The route was deleted in 1957 when US 6 was rerouted out of Bryan and instead traveled on the entire length of the deleted route.

Near the route's end, it turned to the northeast and ended at US 6 east of the city.[6] The route existed from 1935 until 1962 when the state relinquished control of the road.

For its first year in existence, however, SR 568 was signed west of Sylvania along what became SR 120 by 1940. Beginning in 1947, the route east of SR 183 was co-signed with Bypass US 23-24-25. After 1951, the part of Alexis Road co-signed with the Bypass US Routes became solely designated as that route while the remainder of Alexis Road was removed from the state highway system though by 1964, all of Alexis Road was signed as Bypass US 24–25. Today, all of Alexis Road from its western terminus in Sylvania to I-75 (east of the original eastern terminus at Detroit Avenue) is known as SR 184.
