History

The northernmost part of present-day CR 511 near the New York border was made as the Ringwood and Long Pond Turnpike, running from Ringwood to the New York state line. West of Greenwood Lake, the road is now known as the Warwick Turnpike. North of Pompton Lakes, what is now CR 511 was legislated in the 1927 New Jersey state highway renumbering to be the northernmost part of Route 3.State of New Jersey, Laws of 1927, Chapter 319. In 1929, this segment of Route 3 was amended to be the northernmost part of Route S4B, a spur of Route 4. This part of road was never built as a state highway.State of New Jersey, Laws of 1929, Chapter 126.
