No changes occurred to the routing until 1962 when it was renumbered to SR 681 to avoid the duplication with the newly designated Interstate 680 near Youngstown.

The route existed from 1937 until 1941 when it was replaced by Stark County Road 348, also called Orrville Street NW.

[6] SR 695 was a short-lived state route serving as the main road through the Belmont County community of Lloydsville.

[19] SR 723 was a five-mile-long (8.0 km) state highway in Warren and Clinton Counties in central Ohio.

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.

[1] 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).

The route started at West Broad Street (which carried US 40, US 62, and SR 3) and traveled north to US 33 (Dublin Road).

[28][29] 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).

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.

[1] Within one year, SR 31 was back on its original alignment, this time co-signed with the newly signed US 33.

[25] SR 793 was a spur to the Southeastern Ohio Training Center (also called the Boys' Industrial School and the Fairfield School for Boys[37]) 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.

[20][41][42] SR 794 was a two-and-a-half-mile-long (4.0 km) route in Green Township, Clark County serving the Springfield-Beckley Municipal Airport and the Springfield Air National Guard Base.

[28][44] It remained in existence until 2013 when the route and a new alignment built around the National Guard Base was transferred to Clark County jurisdiction.

In 1938, SR 31 was replaced by US 33 southeast of Columbus; as a part of this renumbering, a bypass of Rockbridge was built.

[1][25] 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.

[20][26] In 1965, with the completion of Interstate 70 in the area, SR 797 was extended north about zero point two miles (0.32 km).

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.
