 Originally in the United States, the terms used for special routes were "City", "Truck", and "Optional".In 1959-1960, the terms were changed to "Business", "Bypass", and "Alternate", respectively; however, the "Truck" banner is still used today on many routes, especially those where trucks are prohibited on the mainline (for example, U.S. Route 1/9 Truck in Jersey City, New Jersey, which routes trucks around the Pulaski Skyway, which bans them).The American Association of State Highway and Transportation Officials (AASHTO) has called for the removal of "alternate" routes, though some still exist.
