Pennsylvania Route 97 (PA 97) is one of two Pennsylvania state highways that carries the PA 97 designation; the other PA 97 is in Adams County. The northern PA 97, 21 miles (34 km) in length, is a north-south highway that terminates at PA 8 at both ends. The southern terminus is in Union City and the northern terminus is in Erie. The Pennsylvania Department of Transportation (PennDOT) internally designates this road SR 0197 to distinguish it from the other PA 97.
