Happy new years!
The bridge? It sunk.
Apparently this a mote around an earthen fortress called Fort de Roovere in the Netherlands. The water is too deep to walk thru and too shallow for a keel boat, making it hard for attackers to make it across before they'd be riddled with arrows and other unpleasant things.
To get access to the fort this bridge was recently built by Accsys Technologies out of Accoya wood.
