In the 1927 New Jersey state highway renumbering, Route 37 was legislated to run from Route 27 and Route 30 (now U.S. Route 1 Business, U.S. Route 206, and Route 31) in Trenton continuing through the White Horse Circle and on to Seaside Heights. The western end of Route 37 was once planned to be at White Horse Circle, though that section of the planned route was eventually built as Interstate 195, with other portions returned to the counties as part of Route 524.
