Pictures of U.S. 25E's former route over Cumberland Gap, the Tri-State Trail. Very informative page covering several abandoned freeway proposals in the Metro Houston area. The page covering the defunct Harrisburg Freeway connecting U.S. 59 and downtown with Interstate 610 on the southeast part of the belt is especially interesting. There is a great photo of the abandoned roadway at the stub end of Texas 225. Intriquing look at pre World War II based autobahns throughout western Poland.
