Boston routing of Rt 1

This route first appears on my 1939 map. It ran along Brookline Ave north from its intersection with Jamaicaway (then US 1) to Beacon St. It stayed along the south bank of the Charles, through the Sumner tunnel and up Chelsea St. Along an un-named street to the interesection of Revere Beach Parkway and Beach St, it then headed over to Broadway, up International St to the Bennett Hwy and rejoined US 1. C1 was decomissioned in 1971.
