History

In the 1920s, the current alignment of Route 121 was known as State Highway 195 and was one of the routes between Milford and Derby. In the 1932 state highway renumbering, old Highway 195 became Route 121. In 1941, Route 121 was shortened when US 1 was relocated from Cherry Street to its current route at the Boston Post Road. North Street south of current Route 1 is still signed as the route for the Milford train station.Connecticut Routes, US 1
