America's highways are littered with loose ends. In Houston, relics of an incomplete inner city project loom on the east and west ends with nothing in-between. In Portland, ramps built to merge with the Mt. Hood Freeway simply drop off into an overgrown field.
In the 1930s, construction began on a highway that would cross Pennsylvania’s unruly terrain, following a path developed by the railroad magnate William Vanderbilt. But by the 60s, the route had bypassed a long segment and a narrow tunnel in Breezewood, Pennsylvania. The highway is now slowly being recaptured by nature.
