In the 1920s, State Highway 107 followed today's Route 74 between Routes 83 and 32.

The modern Route 107 was commissioned in 1932. Originally, the 3.6-mile Redding Road segment, between US 7 and Route 53, was part of Route 53 itself; Route 107 itself was 3.79 miles long. In 1963, Route 53 was extended south, and Route 107 got its present configuration.

The state wanted (in 1997) to straighten out some curves in 107 near Georgetown to decrease accidents. All plans involve straightening and widening the curvy road and rerouting several local streets, including Beeholm Road, Goodsell Hill Road and Little Boston Road. Residents are opposed: "This is a speeding problem," said one, and "By straightening Route 107, I think it's going to reward speeders," said another.
