The majority of I-76, along the Pennsylvania Turnpike, includes the first long-distance rural freeway in the U.S.; the Ohio Turnpike and Schuylkill Expressway are also pre-Interstate freeways. By 1955, the section of that route from west of Youngstown to Downtown Philadelphia was included in the planned Interstate Highway System, as was present I-76 from west of Youngstown to Akron. (Some early plans called for a new freeway along SR 14 to the Pennsylvania state line; it is unclear when the proposed route was shifted to the turnpikes.)
