At Riga there is a floating pontoon bridge over the Diina.
Napoleon entered the town hard on their heels, but the broken bridge caused a delay of four days, there being no pontoon trains with the army.
Sometimes a girder is rolled out about one-third of its length, and then supported on a floating pontoon.
On the north side of the fjord is Norre Sundby, connected with Aalborg by a pontoon and also by an iron railway bridge, one of the finest engineering works in the kingdom.
The center rope was put through the center fender eyes and quickly dropped over the center pontoon mooring cleat.
