 From here, I-95 heads onto the Delaware River–Turnpike Toll Bridge, passing over US 13 and Amtrak's Northeast Corridor before crossing over the Delaware River.At this point, the Pennsylvania Turnpike ends and I-95 continues north into New Jersey as the Pearl Harbor Memorial Extension of the New Jersey Turnpike, which connects to the mainline of the New Jersey Turnpike.Plans for a limited-access highway along the Delaware River originated in 1932, as part of a proposed cars-only parkway system for the Philadelphia area similar to the contemporary system being built in New York City.
