Gloucester and Sharpness Canal
United Kingdom
The Gloucester and Sharpness Canal (also known as the Gloucester and Berkeley 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 long 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 (16.5 miles) long.
