Just west of Youngstown, I-76 joins the Ohio Turnpike and heads around the south side of Youngstown. In Pennsylvania, I-76 runs across most of the state on the Pennsylvania Turnpike, passing near Pittsburgh and Harrisburg before leaving the Turnpike at Valley Forge to become the Schuylkill Expressway and eventually entering Philadelphia and then crossing the Walt Whitman Bridge into New Jersey. After I-76 reaches its eastern terminus, the freeway continues as Route 42 and the Atlantic City Expressway to Atlantic City.
