Interstate 95 runs through the city along the Delaware River as a main north-south artery known as the Delaware Expressway. The city is also served by the Schuylkill Expressway, a portion of Interstate 76 that runs along the Schuylkill River. It meets the Pennsylvania Turnpike at King of Prussia, Pennsylvania, providing access to Harrisburg, Pennsylvania and points west. Interstate 676, the Vine Street Expressway, was completed in 1991 after years of planning. A link between I-95 and I-76, it runs below street level through Center City, connecting to the Ben Franklin Bridge at its eastern end.
