 At the signalized intersection with County Line Road, which marked the western terminus of SR 181 when US 30 followed Main Street, SR 181 turns south.Now straddling the boundary between Crawford and Richland Counties, the highway follows the eastern city limit of Crestline and the western limit of Sandusky Township, passing amid several homes up to the point where it crosses the Norfolk Southern Railway.South of there, the terrain becomes more rural, with trees lining both sides of the highway, although not too far beyond the trees on the east side the dominant landscape is farmland.
