This is a footbridge project crossing the ring road motorway surrounding the city of Paris. Redevelopment is currently conducted in the Northern Part of Paris and this pedestrian bridge is planned as a new transportation route between the redevelopment district and the city of Aubervilliers located in the north. By using wood which is the only recyclable material, this would be the world‘s first wooden footbridge over a highway. In order to make a comfortable journey although being on the harsh environmental conditions of the motorway, we are using Accoya which is excellent in sustainability. The acetylation of Accoya greatly increases its sustainability and this would make the world‘s most advanced solid wood. The sequence that leads to a “tunnel of trees” in accordance with the highway and through the wooden deck ramp covered with trees gives a sense of security in the midst of the hustle and bustle. People can gradually enjoy the flow of the traffic beneath.
