designer's own words:AIR WORM In our cities there is no place for cyclists. So we have to take the existing free yet. The idea of this design is to create suspended airways of buildings usable only by cyclists. These suspended airway run through the center of the avenues, with different suspension heights. Can turn into the corners,up and down alternately, to make the trip interesting. The entries and downs would be planned to be located strategically along the route. These airways would give a degree of freedom and security that hardly would be found in the crowded streets of our cities The structure consists of aluminum rings, connected by metal tubes. The rings have elements to put suspended cables. These cables are anchored to the structure of the buildings. In the basic design, inside the rings runs a metal platform with holes, through which run two routes for cycles and lateral areas of security. So, this would make it a simple and healthy walk around the center of the city and see a different urban landscape.
