There is a small town in Pennsylvania called Ashland where Route 61's northbound traffic is temporarily branched onto a short detour. Exactly what the detour is circumventing is not immediately clear to travelers, however few passers-by pay it any mind... a detour is nothing unusual. But anyone who ignores the detour and ventures along the original route 61 highway will soon encounter an abrupt and unexplained road closure. Beyond it lies a town filled with overgrown streets, smoldering earth, and ominous warning signs. Centralia, Pennsylvania was never a particularly large community, but it was once a lively and industrial place.
