Bannered US routes have been in wide use since the early 1930's. Some of the earliest examples I have seen are the US 27A's in central Michigan in 1932. A 1932 AASHO policy statement allowed for cities to erect "Alternate" routes within a city, as long as these routes reconnected with the main route, without AASHO approval. The next year AASHO attempt to regain control of these short system additions, but the states where such routes had been adopted had established a precedent. Many states still consider it none of AASHTO's business if small, local additions to the US route system are posted. These banners have also been seen in the use of an alphabetical-based suffix system, decreasing in importance as the letters progressed: A for for the longer main rooute following Alternate; B for a Bypass around a city center; C for City traffic into the heart of downtown and T for Temporary. Temp US Routes have been suffixed "T" since the 1920's. The suffix B is also used for Business routes by many states now. Y has been seen used for Spur routes. Some states use suffixes as branches and loops off a mainline route, like NY 11B off of US 11. This would be Alt US 11 in many other states, and is not a Business or Bypass route. The primary source for this site was U.S. Numbered Highways - 1989 edition published by AASHTO. Additional information has been gathered from old road atlases and maps, information E-mailed to me, various websites posted by other people, and personal observations. The historical routes for these pages are still being updated, and will be for the forseeable future. Current routes are complete per AASHTO data, and not field verified. Assistance is welcomed and encouraged.
