Consequently, it might be necessary to establish an Infrastructure Agency (or Agencies), modelled on the American "Authorities", e.g. the New York and New Jersey Port Authority, responsible for joint decision-making, and for owning and financing major projects.
Aussi, pourrait-on envisager la mise en place a terme sur le modele des "Autorites" americaines, dont la "New- York New Jersey Port Authority" est l'illustration, d'"Agence(s) d'infrastructures" qui soient a la fois structures de decision commune, entites proprietaires de grands ouvrages, et societes financieres.
