Information on this website has been compiled from countless sources over the course of many years, since 1998.  Numerous people have contributed information, and I also own a small collection of printed maps and atlases dating back to 1928.  But in recent years the quantity of historic maps (and other highway-related information) that has been scanned and put online has greatly increased, much to the benefit of those who enjoy studying the US route system.  I rely heavily on these online sources to provide documentation for the information presented on this website, and this page is an attempt to keep those sources organized and up-to-date.  You can help: it seems that DOT websites get reorganized somewhat frequently, which can cause links to become non-functional.  If you notice any of the links below are dead -- or if you know of another online map source that would be appropriate on this list -- please contact US Ends .com
