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.
