Northward (westbound) crossing the Passaic River into Hawthorne on Lincoln Avenue.
I am mystified as to why the designers of the 500-series road system did not keep CR 504 on Ratzer Road, which becomes Pompton Road on the opposite side of the Hamburg Turnpike. Instead, the highway heads north on Alps Road and then southeast on Hamburg Turnpike before picking up Pompton Road. It is possible that since Pompton Road and Hamburg Turnpike were envisioned as part of the original NJ 3 continuing up to Greenwood Lake, the designers found it best to utilize that routing for CR 504 as far as practical.
The mileage log begins from the highway’s origin in Montville.
