I got fascinated this project. The project is one by dutch architects Ro&Ad architects, called 'Trench Bridge'. ('Loopgraafbrug' in dutch) or also 'Mozes Bridge' For this project they had to create a solution to get people across the water of a historical 17th century fortress defence construction. The solution was quite original and simple. From their general 'cradle to cradle' philosophy the architects always try to find a sustainable and simple solution. Thus they came up with the concept of a 'trench' bridge. The bridge is practically submerged in the water and so when crossing it, one goes beyond water level without getting his feet wet. For the material they used hard wood. The construction is fortified to sustain water pressure. The project made finalist of the 'Dutch Design Award 2011' and made 'BNA Buiding of the Year region South Netherlands' and 'Archdaily Building of the Year 2011-Public Facilities'
