Route 324 is an isolated and partially closed state highway in Logan Township in the U.S. state of New Jersey. The two-lane concrete route runs along the 1.51-mile-long (2.43 km) alignment of Old Ferry Road from the shore of the Delaware River to a cul-de-sac near the interchange between U.S. Route 322 (US 322) and US 130 in Logan Township. The route does not intersect with any state routes or county routes along its entire alignment. The portion from the Delaware River to Springers Lane, consisting of over half of the route, is marked with a "Road Closed" sign, with minimal if any maintenance — potholes and overgrowing vegetation plague this section.
