The river can be crossed on foot or bicycle by a public footbridge upstream from "The Harbour Inn", which leads to the village of Walberswick. This bridge known as the Bailey Bridge rests on the piers and footings of the original iron Southwold Railway swing bridge. It had a central swinging section to allow the passage of wherries and other shipping on the Blyth Navigation, but this was largely removed at the start of World War II under the precautions against German invasion.
