Ohio State Route 568

State Route 568 (SR 568) is an east–west state highway in the northwestern portion of the U.S. state of Ohio. The western terminus of this highway is at a signalized intersection in downtown Findlay where it meets State Route 12 and State Route 37. The eastern terminus of State Route 568 is in downtown Carey at a signalized intersection that serves as all of the northern split of the U.S. Route 23/State Route 103 concurrency, the western split of the State Route 103/State Route 199 concurrency and the southern split of the U.S. Route 23/State Route 199 concurrency. Currently, 2 bridges on the road are going through rehabilitation expected to last until 2025.

State Route 568 was created in the middle of the 1960s. The entire length of this two-lane highway is part of the former alignment of State Route 15, which was realigned onto a new expressway from Findlay to Carey at that time.

History
State Route 568 was established in 1965. With the completion of a new four-lane divided expressway from Interstate 75 south of Findlay and U.S. Route 23/State Route 103 south of Carey, the State Route 15 designation, which had utilized a two-lane roadway between downtown Findlay and downtown Carey to that point, was transferred onto the new expressway, which parallels the two-lane road to the south. Consequently, this two-lane highway became known as State Route 568. The route has utilized the same alignment from inception to this day, and has not seen any significant changes since its original designation.

Prior to the presently designated Route 568, a previous Route 568 traversed northern Lucas County and Fulton County. Established around 1939, its western terminus was the Ohio–Michigan line west of Lyons and the eastern terminus was at U.S. Route 25 (North Detroit Avenue) in Toledo. However, within a year, the part west of old U.S. 223 (present day Monroe Street and Alexis Road in Sylvania) was renamed Route 120 due to difference of traffic. Subsequently only the portion east of Monroe Street remained as Route 568, entirely encompassing Alexis Road. It was decommissioned as a state route around 1953 and designated as a bypass for U.S. 24 and U.S. 25. It was recommissioned as State Route 184 in 1969.
