Walney Channel

The northern portion of the channel opens into the Duddon Estuary and is both narrower and shallower.

The southern half of the channel is wider and is regularly dredged to allow shipping to access the Port of Barrow.

[1] This half opens into Morecambe Bay.

Because of the needs of navigation, particularly the activities of the Vickers shipyard, it was constructed as a bascule bridge.

The bridge that crosses the channel is also part of the A590.
