An Act relative to historic route designations

This bill designates Massachusetts Routes 1, 20, and 6 as "historic United States Routes." It requires the Massachusetts Department of Transportation (MassDOT) to install and maintain clear markers along these routes, following department standards. The law directly affects MassDOT's responsibilities for highway signage and applies specifically to those three state routes. The change is purely administrative, focusing on route identification without altering traffic laws or funding.
