Rapid Run, a trout stream that is stocked by the Pennsylvania Fish and Boat Commission, flows through Sand Bridge State Park. The park attracted 17,000 visitors in 2008. The name Sand Bridge remains a mystery. No one, according to the parks official website knows why the area is known as Sand Bridge.
