Around 2005, a road was built stretching north from the northern end of the bridge was built. This new road, which ended away from a newly created intersection with SR 607 at Irene Road was designated SR 607-T. In 2007, both sections of SR 607 were deleted and was replaced by an extension of SR 775 except for the ramp from the north-south road to SR 7, the ramp became a part of SR 7 when it was routed on a bypass of Proctorville. SR 612 was the designation for a state-maintained section of West 130th Street in Cuyahoga County. The route started at SR 82 (Royalton Road) on the border of Strongsville and North Royalton and traveled due north. SR 612 traveled along the borders of Strongsville, North Royalton, Middleburg Heights, Parma, Parma Heights, and Brook Park. SR 612 reached SR 17 (Brookpark Road) at the city limits of Cleveland. This intersection served as the northern terminus of SR 612 from 1937 until 1939. After 1940, SR 612 continued north into Cleveland for about to SR 10 (Lorain Avenue). The route was deleted from the state highway system between 1951 and 1953. SR 613 was a state route in southeastern Cuyahoga County. The route carried Richmond Road from Broadway Road (at the time also SR 14) to Aurora Road (SR 43) in Glenwillow and Solon. SR 613 existed from 1937 until 1945 when it was replaced by SR 175 though today, the road is not state-maintained at all. SR 614 was state route in Lake County. The route started at SR 86 in Concord Township, traveled east, and ended at SR 166 (signed as SR 528 after 1940) in Madison Township. The route was signed from 1937 until after 1942. SR 622 was a state route entirely in Poland Township that existed from 1937 until 1941. The route started at SR 18 (modern-day SR 289) near the city limits of Struthers and traveled east along New Castle Road (currently Mahoning County Road 106) before ending at the Pennsylvania state line, though the road continues in Pennsylvania as Skyhill Road. SR 623 was a state route on the Stark–Mahoning County county line in existence from 1938 until 1941. The route also formed the border between the city of Alliance and Smith Township. The short route, also called Mahoning Avenue, connected US 62 (East State Street) with East Patterson Street, which was signed as SR 173 while SR 623 existed.
