The Walk of the acqueduc of Dhuis

The Agence of the green areas of the area of Ile-de-France (AEV-IdF) signed in 1997 a convention with and EauDeParis (SAGEP) a convention for the installation of a 27 km length continuous walk, between the Parisian crown and the edges of the Marne, on the work which belongs to the Ville of Paris.

This installation, evaluated with 6 million euros, is financed by AEV-IdF, and relates to 13 communes located in Seine-Saint-Denis and Seine-et-Marne.

The walk will have a variable width from 10 to 20 meters, that is to say a total installation of approximately 37 Hectare S, allowing the realization of a walk pedestrian and cyclist.

In order to protect the viaduct and the drinking water which circulates there, the riders will not be allowed (possible pollution of the aqueduct), and there will be no plantations of trees in the influence (mini distance of 6 m on both sides of the axis of the viaduct)

The design of the project is due to the assisted agency of landscape designers Signes Tugec research department, retained in 1999 after an international contest, which is structured by the will to carry out a green ribbon in balcony on a large variety of landscapes .

The inauguration of the walk is envisaged in spring 2008. Work was completed to 75% at the end of 2006.
