This study day takes the occasion of the fiftieth anniversary of the completion of the Paris ring road to question the past and present of this infrastructure as an object of research.

What technical and technocratic political project is it the incarnation? Does it remain the archetype of all-automobile urbanism? The border of a small Paris prevented from becoming big? The spatialization of a distrust of the city center for “its” suburbs? Is the ring road just an obstacle, or even a boil emitting atmospheric and noise pollution, with cracked and tired concrete?

Half a century old, it remains one of the busiest sections of urban roads in Europe. Several times announced as dead, buried, abolished, the ring road continues to operate the “no red lights” loop promised in 1973 and to be an essential road infrastructure for the Paris region. It is the subject of numerous architectural, urban planning and landscape proposals: the most recent being roofing projects, construction of bridge buildings, reduction in the number of lanes for automobiles, construction of cycle paths or rebirth of the project of a “green belt” promised at the turn of the last century. This seminar will take stock of recent research.

Round table at 5 p.m. with :

  • Patricia Pelloux, deputy director and director of metropolitan studies at Apur
  • Bernard Landau, honorary road architect of the City of Paris, president of the association La Seine est pas for sale
  • Antoine Soulier-Thomazeau, director of planning and travel of the public territorial establishment of Grand Paris Est ensemble
  • Mathieu Flonneau, lecturer at Paris 1 Panthéon-Sorbonne University
