1927 New Jersey state highway renumbering

A partial renumbering was proposed in 1926 to get rid of the duplicates and assigning numbers to many of the unnumbered routes. The proposed 1926 renumbering would have: • extended Route 4 over Route 19 • renumbered Route 17N to Route 17 • renumbered Route 18N to Route 18 • renumbered Route 18S to Route 19 • designated Route 21 from Trenton to Buttzville • renumbered Route 17S to Route 22 • renumbered Route 18 (unsuffixed) to Route 23 • designated Route 24 from Mount Holly to Freehold • renumbered the Route 20 "from a point on Route No. 3, extending by way of West Berlin, Gibbsboro and Haddonfield, connecting with Haddon Avenue in the Borough of Haddonfield, and continuing to approach the Delaware River Bridge" to Route 25, and extended it from West Berlin to Blue Anchor • designated Route 26 from Five Points to Hammonton • designated Route 27 from Camden to Atlantic City • designated Route 28 from South Amboy to Atlantic Highlands • designated Route 29 from Morristown to Hackettstown • designated Route 30 from Far Hills to Tri-State It was eventually determined that an entire overhaul of the numbering system was necessary. == Design ==

Chapter 319 of the 1927 public laws defined the new system of routes. Major roads received numbers from 1 to 12 and 21 to 50, as follows: • 1-12: northern New Jersey • 21-28: radiating from Newark • 29-37: radiating from Trenton • 38-47: radiating from Camden • 48-50: southern New Jersey Spurs were also defined, being assigned a prefix of S. For example, Route S26 was a short spur of Route 26 connecting to Route 25 south of New Brunswick. A second spur of Route 4 was assigned Route S4A, but two separate spurs of Route 24 both received the Route S24 designation. While the majority of already-acquired routes were included in the new system, four sections of pre-1927 routes were not. The law authorizing the renumbering indicated that these were to remain, and so the State Highway Commission added a suffix of N to distinguish them from the new routes of the same number: • Route 4N from pre-1927 Route 4, Eatontown to Belmar • Route 5N from pre-1927 Route 5, Morris Plains to Denville • Route 8N from pre-1927 Route 8, Sussex to Unionville, New York • Route 18N from pre-1927 Route 18N, Fort Lee to Alpine ==List of new routes==

1929 amendment Chapter 126 of the 1929 public law amended the 1927 act, removing redundant designations and creating entirely new roads in the New York Metropolitan Area. The amendments included • Realigning Route 1 onto Route 18N, still left over from the first 1916 system • Establishing Route S1A, today Route 67, from the remnants of Route 18N not taken over by Route 1 (Lemoine and Palisades Avenues) • Truncating Route 3 to the Hawthorne-Paterson Line • Establishing Route S3 (served by modern Route 3), running from Route 3 in East Rutherford to Route 6 in Clifton • Declaring that Route S4A would be built, "provided, however, the county of Atlantic shall first agree to construct a suitable continuation of said road from Little Beach to the city of Atlantic City". Atlantic County was unable to build most of this extension, hence Route S4A was never built; the portions that were built became designated as Route 87 • Establishing Route S4B, replacing the truncated sections of Route 3 (served today by Route 208) • Truncating Route 5 to roughly its current length, with an extension to the centre of Ridgefield • Realigning Route S5 onto the southern portion of Grand Avenue (modern Route 93) • Realigning Route 6 to a new alignment east of Caldwell Township, bypassing Paterson • Creating Route S6 (including modern Route 62) along the portions of Union Boulevard formerly used by Route 6 • Truncating Route 7 to Wallington Other additions ==Notes==
