Pavillon de l'Arsenal - roads for the future
Inaugurated June 6 through until September 1st, the exhibition displays our work undertaken with Holos, the Metropolitan Forum consortium led by Richez_Associés, on the future of the motorways and expressways within the A86 ring road.
Alongside three other teams led by architects - Devillers & Associés, Seura, Rogers - we consider it urgent to reduce the number of vehicles that use these motorways within dense urban areas, especially for health reasons. To meet this objective, a massive change towards public transport that uses express buses in dedicated lanes is necessary.
Furthermore, we particularly stress the importance to permanently communicate the impact of the change; overhead signs should display in real time the number of passengers transported on buses in these dedicated lanes, far superior than those conveyed by roads congested by unaccompanied motorists. We also draw attention to the potential for environmental benefits provided by these dedicated lanes and interchanges - their reconfiguration makes possible a reduction in the number of vehicles and the conversion of the connection ramps into intersections with traffic lights, extensively replanted to make them permeable, and the transformation of these hot bitumen corridors (+5° to 10° in comparison with the metropolitan area) into cool corridors to ventilate Greater Paris. The reclaimed spaces and fringe areas will be complemented with by additional cross links to reduce the backtracking that impinges upon the infrastructure. Finally, in many places they create magnificent perspective views of the imposing metropolitan landscape. These should be improved to accommodate walks, jogging and many other uses; recreational activities that will reconcile these large infrastructures with the attributes of the metropolitan region.
