History
OH 193 was designated between 1967 and 1969 along a former portion of OH 170 from US 422 in Youngstown to its current northern terminus in North Kingsville. From US 422 to US 20 in North Kingsville, this route was the former OH 90 from 1926 to 1962. The former OH 90 was then extended north to OH 531 in 1940. Meanwhile, the freeway section of OH 193 between US 422 and its current southern terminus at I-680 was completed at around the same time that OH 193 was assigned.
A previous iteration of OH 193 existed between 1924 and 1940. The original OH 193 was routed from the Indiana state line 3 miles (4.8 km) west of Hicksville to Hicksville along the current alignment of OH 18. In 1940, the entire alignment became certified as OH 18.
