Route description

No part of SR 198 in Ohio is included as a part of the National Highway System (NHS).[2] The NHS is a network of highways that are identified as being most important for the economy, mobility and defense of the nation.[3]

SR 198 heads north from an interchange with U.S. Route 33 concurrent with SR 67 and SR 501. The road enter downtown Wapakoneta where SR 67 turns east and both SR 198 and SR 501 turn west. The two routes head west and then turns towards the northwest. Just before leaving Wapakoeta SR 501 leaves the concurrency heading due north. The highway now enters rural Auglaize County passing through farmland. Before the road enters Allen County is an intersection with SR 197. The route enters Allen County and has an intersection with SR 117. This intersection is the northern terminus of SR 117.[4]
