The Secret Sidewalk

The East Bay’s very own Niles Canyon, a long-abandoned aqueduct, attracts the curious to the unusual trail known as the Secret Sidewalk in Fremont. Well-known to locals the six-foot Niles Canyon Aqueduct carried water from the Alameda Creek to the Sunol Filter Galleries through the Niles Reservoir for numerous years. The aqueduct provided the unincorporated area of Alameda County with freshwater during the 1920s and years later. Past a metal gate donning a “Keep Out: No Trespassing” sign, an aged rusty fence, and a hazardous hike the trespasser finally reaches the notorious aqueduct. The long solid concrete block is wide enough to serve as a sidewalk as the pavement wraps around the canyon and through a few private properties. In addition to the spooky and desolate atmosphere of the Secret Sidewalk it has, over several years, been defaced with layers of graffiti concealing the entire structure. - See more at: http://thepioneeronline.com/21049/metro/the-many-mysteries-of-fremonts-secret-sidewalk/#sthash.yuKun...
