The Gloucester and Sharpness Canal is a ship canal in the west of England, between Gloucester and Sharpness, completed in 1827. For much of its length the canal runs close to the tidal River Severn, but it cuts off a significant loop in the river, at a once-dangerous bend near Arlingham. It was once the broadest and deepest canal in the world. The canal is 26.5 km long.
