SR 692 was a state route in Scipio Township connecting SR 143 between Walsh and Harrisonville to SR 680 (later SR 681) north of Pageville. The route also intersected SR 684 at SR 684's northern terminus in Pageville. The route existed from 1937 until December 2013 when most of the route was transferred to Meigs County jurisdiction. North of SR 684, the road became a part of SR 684.
SR 695 was a short-lived state route serving as the main road through the Belmont County community of Lloydsville. Prior to 1939, US 40 ran through the town, but in 1939 a bypass was built north of the community. SR 695 was designated onto the old main road when US 40 was moved to the bypass. Within one year, SR 695 was replaced by US 40 Alternate, a designation that would last until the 1960s.
SR 702 was a short state highway spur from SR 235 to Turkeyfoot Point on the Indian Lake shoreline entirely in Stokes Township, Logan County. The route was designated in 1940 and remained on this alignment until 1977. Today, the former state route is a township-maintained road (T-293).
SR 704 was the designation for what is now SR 81 between Willshire and Lima from 1937 until 1939. The route was replaced by SR 81 which formerly ended in Ada when it was extended through Lima.
SR 723 was a five-mile-long (8.0 km) state highway in Warren and Clinton Counties in central Ohio. The route started in Harveysburg at SR 73 and ran north to SR 380 near New Burlington. The entire route generally followed the Caesar Creek between its two ends. The route existed from 1939 until 1945 when it became a local road. Today, part of the road is under water as the Caesar Creek Lake was filled in the 1970s as a part of the creation of Caesar Creek State Park.
SR 751 was a state highway in and around the eastern side of Columbus. When it was first designated in 1937, the route was about one-and-a-half-mile-long (2.4 km) and ran from US 40 to SR 16, paralleling the Big Walnut Creek for its entire length. Two years later, SR 751 was extended south to US 33 southeast of the city bringing the total length to 6.5 miles (10.5 km). Again, the entire route closely followed Big Walnut Creek. The route was deleted after 1959 being replaced by mostly local roads as by the time of its deletion, most of the land through which SR 751 passed through had been incorporated.
SR 773 was the designation for what is now SR 162 between Rochester and Akron in 1937. After one year signed, the entire route was replaced by SR 162, which during the time of SR 773's existence, had its eastern terminus in New London. SR 162 was routed over a new road between New London and Rochester to connect to SR 773 and continue to Akron.
SR 782 was a state-maintained section of Sandusky Street in DowntownColumbus. The route started at West Broad Street (which carried US 40, US 62, and SR 3) and traveled north to US 33 (Dublin Road). When the route was created around 1949, the northern terminus was at an intersection with US 33, but by 1955 the northern terminus was reconstructed to an interchange. The route was still in existence in 1957, but later the right-of-way of Sandusky Street was obliterated by the construction of the West Innerbelt (first a section of Interstate 71, now a part of SR 315).
SR 791 was a state route in and around Canton along Raff Road between an intersection with Navarre Road (US 62) and Canton-Massillon Road in Canton Township to Tuscarawas Street (US 30) in Canton. The route was created in 1946. Following the completion of the US 30 / US 62 freeway through Canton, the route at SR 791's northern terminus became SR 172 but the route's southern terminus remained at what used to be the Navarre Road intersection. 1976 was the last year SR 791 appeared on the official Ohio highway map, but the route remained in the Stark County traffic logs through 1988.
SR 793 was a state route located in northwestern Columbus for one year, 1937. Until 1937, the route that SR 793 would follow was signed as SR 31. In 1937, SR 31 switched the route it used to enter Columbus; SR 31 headed south to US 40 while SR 793 was routed from Marble Cliff to northwestern Columbus at US 23. Within one year, SR 31 was back on its original alignment, this time co-signed with the newly-signed US 33.
SR 793 was a spur to the Southeastern Ohio Training Center (also called the Boys' Industrial School and the Fairfield School for Boys) in Hocking Township, Fairfield County to the city of Lancaster. The route started at the entrance to the training center and traveled north for 4.8 miles (7.7 km) to an interchange at South Memorial Drive, which carried US 33 during the time of SR 793's existence. SR 793 was designated in 1959 and had its jurisdiction transferred to Fairfield County and Lancaster City on May 23, 2006. The section of the route within the city is now only called South Broad Street while the former route outside of it is called Fairfield County Road 90.
SR 794 was the designation for a state-maintained section of Washingtonville Road and short portion of Western Reserve Road in southern Mahoning County. The route started in Washingtonville at SR 14 (which straddled the Mahoning–Columbiana County line) and traveled north through Green Township before reaching a T-intersection with Western Reserve Road on the Green-Canfield Township. SR 794 then traveled east to end at a nearby intersection with SR 46 in the community of Marquis. The route was created in 1937 as a dirt road and was paved within one year. SR 794 was decommissioned between 1942 and 1945 and replaced by Mahoning County Road 95 (the north-south portion) and CR 32 (the Western Reserve Road portion).
SR 796 was the designation for a former segment of SR 31 through the Good Hope Township community of Rockbridge. In 1938, SR 31 was replaced by US 33 southeast of Columbus; as a part of this renumbering, a bypass of Rockbridge was built. SR 796 was assigned on the two-mile-long (3.2 km) former two-lane road through the area. The route would remain along this alignment until 1964 when it was removed in conjunction with the construction of the US 33 expressway through the county. All of the former route along Rockbridge Road A, Main Street, and Jackson Street is now known as Hocking County Road 10.
SR 797 was a state route in Portage County connecting SR 43 in Franklin Township (just north of Kent to SR 82 in the Mantua Center section of Mantua Township. Throughout its history from 1939 until 1941, the portion of the route between SR 43 and SR 14 was asphalt-paved, the section between SR 14 and SR 303 including its concurrency with it was gravel-paved, between SR 303 and halfway to Mantua Center was a dirt road, and the remainder was gravel. Today, most of the former route is called Diagonal Road and Portage County Road 155, though the latter is not designated through the portion that is now part of incorporated Streetsboro.
SR 797 was a route in Perry Township, Muskingum County that served the Zanesville Municipal Airport about six miles (9.7 km) east of the city of Zanesville. It was initially created in 1946 running from the airport's entrance to an intersection with US 22 and US 40. In 1965, with the completion of Interstate 70 in the area, SR 797 was extended north about zero point two miles (0.32 km). The total length of the route was 1.19 miles (1.92 km) from the time of the extension until 2003. That year, the portion south of US 22/US 40 was transferred to county jurisdiction with the short remainder of the route between US 22/US 40 and I-70 becoming county-maintained by 2014.
SR 798 was a state route in Belmont County connecting SR 647 and the northern city limits of Martins Ferry at SR 7. The route ran through mostly hilly terrain between its two termini. The route was first signed in 1939 and last appeared on the Ohio state highway map in 1978 but the route did appear in the 1980 Belmont County traffic report. Today the former SR 798 is a part of Deep Run Road (Belmont County Road 2) and Nixon Run Road (CR 16).
