The main purpose of building NJ 5 was to avoid some of the steep grades on previously existing roads like Edgewater Avenue and Fort Lee Road.
NJ 5 became superfluous when the George Washington Bridge was opened and NJ 6 (now US 46) was built. However, once New Jersey builds a road, it generally maintains it forever, so NJ 5, which is still used as a connector between Fort Lee and Edgewater, remains under state control.

 This unorthodox CR 54 marker (which doesn’t even identify the county) is on NJ 5 westbound just east of Anderson Avenue, outside the brief concurrency with CR 54 (now CR 24). Perhaps there should be a straight-ahead arrow accompanying it? | ||
