1953 renumbering

On January 1, 1953, the New Jersey Highway Department renumbered many of the State Routes. This renumbering was first proposed in 1951 in order to reduce confusion to motorists. A few rules were followed in deciding what to renumber:

New numbers assigned semi-arbitrarily included 15 and 20 (13-20 were not assigned in the 1927 renumbering), the sequence from 57 to 93, and 152 to 165 for minor routes (continuing from pre-renumbering 151).
