1930 state highway renumbering (New York) (original) (raw)

In January 1930, the U.S. state of New York implemented a major renumbering of its state highways. Many previously existing numbered routes were renumbered or realigned. At the same time, many state highways that were previously unnumbered received designations. Most of the highways with numbers in the 100s to 300s were assigned at this time. Route numbers were assigned in clusters based on their general location. Because some of these route numbers are no longer in use, the pattern of clusters is not fully apparent today.
