Since 1953, the Ohio General Assembly has designated portions of the state highway system as a memorial highway by passing legislation which is then signed into law by the Governor. Through Ohio Revised Code Chapters 5533 and 5534, the General Assembly has established more than 200 memorial highways.
The majority of highway designations are memorial designations for military personnel killed in action and public servants; however, highways may be designated in honor of events, groups, and other persons significant to the state or a region of the state (the Ohio House and Senate may offer further criteria). A highway designation will not change the official highway route number or name. Some highways have multiple highway designations at various points along the route.
The Ohio Department of Transportation supports these memorials by producing and installing signs at the designated locations.
