Piece of the Artificial Harbors.
The dock piers were code named 'Whale'. These piers were the floating roadways that connected the 'Spud' pier heads to the land.
The roadways were made from torsionally flexible bridging units that had a span of 80 ft., mounted on pontoon units of either steel or concrete called 'Beetles'.
After the war many of the 'Whale' bridge spans from Arromanches were used to repair bombed bridges in France, Belgium and Holland.
