State Route 197 (SR 197, OH 197) is 25.28-mile (40.68 km) east–west state highway in the western part of the U.S. state of Ohio. The western terminus of SR 197 is at a signalized intersection in downtown Celina that marks the junction of U.S. Route 127 (US 127), SR 29 and SR 703. SR 197 has its eastern terminus at SR 198 nearly 2 miles (3.2 km) southeast of the village of Buckland.

Route description

Along its path, SR 197 passes through the northeastern quadrant of Mercer County and the northwestern portion of Auglaize County. There are no segments of SR 197 that are included as a part of the National Highway System (NHS). The NHS is a network of highways that are identified as being most important for the economy, mobility and defense of the nation.^[5]

History

The SR 197 designation was applied in 1923. It was originally routed along much of its present alignment, from its western terminus in downtown Celina to its junction with SR 66 south of Spencerville.^[1][2] SR 197 was extended to the east in 1937, routed along previously county-maintained roadways to its current eastern terminus at SR 198.^[6][7]
