History
SR 587 was designated in 1937. The highway originally consisted of today's Wyandot County Road 35 from SR 67 approximately 2 miles (3.2 km) southwest of Sycamore to the intersection marking SR 587's southern terminus at SR 53 in McCutchenville and the entirety of the current SR 587. In 1965, the portion of SR 587 southeast of McCutchenville was removed from the state highway system. Jurisdiction of this stretch of roadway was transferred to Wyandot County, who then designated it as County Road 35.
