On December 1, 1954, the first stretch (the portion lying east of SR 18) opened near the present-day exit 218 for I-76 and I-80. Several motorists attended a dedication ceremony, with over 1,000 people joining a caravan, following a snow plow and a patrol cruiser, to become the first to drive the turnpike. The remaining section from exit 218 west to Indiana opened on October 1, 1955. A connecting ramp near the Indiana state line closed on August 16, 1956, the day before the Indiana Toll Road was opened; this ramp had been used to allow traffic access to US 20 to cross into Indiana.
