State Route 587 (SR 587) is a north - south state route in the northwestern quadrant of the U.S. state of Ohio. The highway's southern terminus is at SR 53 in the census-designated place of McCutchenville about 5miles southeast of New Riegel. Its northern terminus is at a T-intersection with SR 18 in the southeastern corner of the city of Fostoria.
SR 587 is located in the extreme northern portion of Wyandot County and the southwestern quadrant of Seneca County. This highway is not included as a component of the National Highway System, a network of highways deemed most important for the country's economy, mobility and defense.[2]
SR 587 was designated in 1937. The highway originally consisted of today's Wyandot County Road 35 from SR 67 approximately 2miles 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.[3] [4] In 1965, the portion of SR 587 southeast of McCutchenville was removed from the state highway system.[5] [6] Jurisdiction of this stretch of roadway was transferred to Wyandot County, who then designated it as County Road 35.[7]
