If you're traveling around the US and you'd like to know if there's construction, or a crash, congestion or bad weather, each state Department of Transportation (DOT) has the map for you! You can call 5-1-1 for transportation and traffic information in many states (Wikipedia), and all state DOTs maintain online traveler information maps, if you want to find individual maps. But what if you want to travel between states? Highway Conditions (dot com) provides links to Canadian provinces and territories, and the United States plus D.C. and Puerto Rico, but there's a bit of link-chasing, and only some state maps link to their neighbors, but not all, so here's a list of all 50 states, from Alabama to Wyoming, Maine to California, sea to shining sea.
