In 1916, the Lincoln Highway was legislated as part of Pre-1927 Route 1 (New Jersey) between New Brunswick and Elizabeth and as pre-1927 Route 13 between Trenton and New Brunswick in 1917. In the 1927 New Jersey state highway renumbering, Route 27 was designated to run from Trenton to the intersection of Frelinghuysen Avenue and Astor Street in Newark, replacing the portions of Routes 1 and 13 that ran along the Lincoln Highway. With the creation of the United States Numbered Highways, U.S. Route 1 was designated along the length of Route 27 from 1927 until sometime before the 1940s, when the U.S. Route 1 designation was moved to New Jersey Route 26, New Jersey Route S26, and New Jersey Route 25 between Trenton and Newark. U.S. Route 206 was designated along the portion of route between Trenton and Princeton, New Jersey by the 1940s. In the 1953 New Jersey state highway renumbering, the southern terminus of Route 27 was cut back to Princeton to avoid the U.S. Route 206 concurrency.. Before the terminus of route 27 was cut back to Princeton, where did it end?
