I-76 continues east as I-80 and I-80 continues southeast as I-76, carrying the turnpike with it. In Petersburg, the concurrent routes cross the state lines into Pennsylvania, automatically becoming the Pennsylvania Turnpike. History In 1947 a bill was introduced in the Ohio General Assembly authorizing a privately financed roadway. Originally consisting of a system of five highways, the turnpike was reduced to one when the other four were made redundant by the Federal Aid Highway Act of 1956. Construction for the road cost $326 million and was recorded as the biggest project in state history, with 10,000 employees, more than 2,300 bulldozers, graders, loaders and other machines over a 38-month period. 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. The turnpike was named after the first chairman of the commission, James W. Shocknessy, in 1976. Originally, the turnpike offered 18 access points. Additional access points have since been provided, bringing the total number, including the Westgate and Eastgate toll barriers, to 31. Not included in this count is the unnumbered interchange at SR 49, which opened on December 29, 1992. There are no ramp tolls at this interchange; the Westgate toll barrier was, at the same time, moved from its previous location near the Indiana state line to its current location, which is east of SR 49. In 1996, the turnpike began a project to add one lane in each direction from Toledo to Youngstown. The project, using financing from increased tolls, was originally projected to be finished in 2005, but was not completed until the end of the 2014 construction season. In 1998, the Ohio Turnpike Commission began phasing in distance-based exit numbers; the sequential numbering system was retired in September 2002. In 2009, the Ohio Turnpike Commission began accepting E-ZPass for toll payment at all plazas, and added gates to toll
