CR 501 is mostly overlaid atop the old CR 33. It utilizes sections of both NJ 63 and NJ 93 in Bergen County before heading north to the New York state line at Piermont, paralleling the route of the Northern Railroad. Through Englewood, Grand Avenue (north of Van Nostrand Avenue) and Engle Street are one-way northbound; southbound traffic entering Englewood uses Ivy Lane, Hudson Street, Dean Street, and Van Nostrand Avenue. However, this route is not inventoried as a county road.
The mileage log is from the start of the route in Edison.
