Ohio State Route 89 is a north-south route found only in Ashland County. This is about midway between Columbus and Cleveland. The southern end is at Ohio Route 95, near Ohio Route 179 and the unincorporated hamlet of Mohicanville. From there, Ohio Route 89 proceeds northward to serve Jeromesville. It crosses US Route 250 several miles east of Ashland. Ohio Route 89 stays east of Ashland, progressing north to serve the tiny town of Polk. The final portion of Ohio Route 89 bends northwesterly to reach Ohio Route 58, which can be used to progress farther northward into Lorain County.
