In the 1920s, State Highway 337 followed today's Route 162.

The streets that became modern Route 337 (Silver Sands Rd, South End Rd, and Townsend Ave.) were city-maintained until 1963, when they became part of an extended Route 142.

In 1970 or 1971, however, Route 142 was moved back to its original location (same as it is today.) The abandoned portion of Route 142, the three streets mentioned above, became unsigned secret route SR 704.

On Sept. 15, 1987, SR 704 became Route 337.
