Early in the 19th century, the Leiper Canal ran about 3 miles (5 km) along Crum Creek in Delaware County, Pennsylvania. George Leiper, who financed the canal, used it between 1829 and 1852 to haul stone in flat-bottomed boats from his quarry near Springfield to the navigable Delaware River at Eddystone. The system, which had three locks, replaced an industrial tramway.
