Cross Ledge, and underwater ridge about three miles long in Delaware Bay is located about 25 miles up the bay from the mouth.  The waters are dangerously shallow, constituting a navigational hazard, and have been marked by a lightship, and subsequently a screw pile lighthouse that was finished in 1856.  Unfortunately, the ice that winter took the entire screwpile base in an ice flow.

The foundation for the Cross Ledge lighthouse was begun in 1874 and completed in 1875.  The frame lighthouse that was subsequently had two floors topped by a cylindrical watch room and lantern room.  Sadly, Cross Ledge lighthouse was made obsolete by the construciton of the Miah Maull shoal and Elbow of Cross Ledge lights.  The lighthouse was abandoned in 1910.

The lighthouse stood for several decades, finally being used for bombing practice during the World War II.  For safety reasons, the Coast Guard burned what remained of the Cross Ledge lighthouse in 1962.  Now, only the foundation and some of the rip rap from around the base are all that remain of the Cross Ledge light in Delaware Bay.
