The Invisible Bridge – RO&AD Architects – Netherlands

Designed by RO&AD Architects of the Netherlands and Belgium, this pedestrian bridge is an access route to the Fort de Roovere, part of the 17th century defense structures. The concept behind the bridge is simple; to give people the illusion of being able to walk through water. Built with Accsys Technology, Accoya wood undergoes a nontoxic proprietary modification process called acetylation that renders it an unrecognizable wood source, preventing fungal decay from the exposure of water and moisture while increasing its structural stability. While this water walkway is simple in concept, it is quite complex in its execution. Officially dubbed the Mose Bridge, this is as clever as it is an architectural achievement.
