 The route was designated in 1967, taking over the Hingham and Hull portions of the circumferential Route 128 when that route was truncated back to its intersection with Route 3 in Braintree.The Route 128 designation was established in the late 1920s.Due to complaints about the amount of traffic on Hingham's historic Main Street and other roads in town, the state first proposed building a bypass route starting in the 1930s, however there was never enough funding to start construction.
