The route passes farmland to the north and Lincoln Park Airport to the south, fully entering Pequannock Township at the Beaverbrook/Hillview Road intersection.

Upon reaching an intersection with CR 689, the route turns east onto four-lane Paterson-Hamburg Turnpike, which heads through commercial areas.

[1][3] CR 504 continues southeast on two-lane undivided Pompton Road, passing by the main entrance of William Paterson University.

After crossing a stream, CR 504 forms the border between Prospect Park to the northeast and Haledon to the southwest, entering more urbanized residential development.

[1][3] The road enters Prospect Park again as it begins to run along the west bank of the Passaic River, crossing CR 652.

At this point, CR 504 becomes Wagraw Road and heads northeast into business and industrial areas prior to turning east near homes.

At this point, CR 504 turns south onto Lincoln Avenue, and briefly runs between Hawthorne to the west and Fair Lawn, Bergen County to the east before crossing the Passaic River.
