Route 121 connects central Milford to the Merritt Parkway and Route 34. It's close to two other parallel north-south highways: Route 142 and Route 114. It's also a rare state route that crosses I-95 with no interchange or signs explaining how to get to it.

CT 121 History

In the 1920s, State Highway 121 followed today's US 44 from US 7 to the New York state line. This road became Route 199 in 1932, and part of US 44 in 1935.

The modern Route 121, commissioned in 1932 from the old SH 195, hasn't changed since then, except for getting shortened by 0.06 miles when US 1 moved from Cherry Avenue to the Boston Post Road in Milford.
