The Dutch-Belgian practice’s wonderful floating bridge provides pedestrian access and an emergency exit from the Ravelijn op den Zoom fortress. Located on a small island and surrounded by a deep-water moat, the centenary building is currently used for hosting private events. Built by military engineer Menno van Coehoorn, the fortress was, at one stage, only accessible by boat.
That same boats’ path is what inspired the curvy bridge’s shape. Measuring 262-feet, it was built from a high-performance wood product called Accoya, resistant to fungi and swelling-shrinkage effect. This is extremely important as the bridge is only kept afloat by air-filled polyethylene pipes underneath and no other structural framework at all.
