been made. The only change to the highway came in 1962 when Ohio renumbered state highways that shared route numbers with proposed Interstates. Because of I-71, SR 71 was renumbered to SR 571. An unrelated SR 571 was in existence from 1937 to 1957 in Bridgewater Township, Williams County. This SR 571 ran from US 20 to the Michigan state line. In 1957, SR 576 was extended north and took over the highway.
