As in, you are forbidden to drive a car on it, but you can bike, walk, or ride a horse on it. The former Wissahickon Turnpike, the main drag through Wissahickon Valley Park in Philadelphia, was built in the 1820s and got its current name in the 1920s when it was closed to vehicles.

As peaceful as it is, Hanover Pond is part of what has been called a “highly engineered agricultural water supply system” for growing cranberries. Whitesbog was already a large, established cranberry operation when Gaunt’s Brook was dammed in 1896 to create Hanover Pond. Water from the pond is channeled into Whitesbog’s Upper Reservoir, built around the same time.
