A little history...
Creation of the Boulevard Circulaire de La Défense
The Boulevard Circulaire de La Défense, forming a one-way road ring surrounding the business district, isolates it from the neighbouring districts of Puteaux and Courbevoie. A real urban motorway, reserved for cars, pedestrians cross it by footbridges or underpasses.
2004 à 2008
Redevelopment of Boulevard Circulaire de La Défense and Boulevard Gambetta in Courbevoie The opening of the A14 motorway in November 1996 made it possible to envisage the reconfiguration of the Boulevard Circulaire de La Défense into a boulevard with an urban character, more legible, more humane, calmer, offering safe pedestrian crossings, a 2km long two-way bicycle path and landscaping. This qualitative development has made it possible to reduce the space for cars, 22,000 sq.m less pavement, create sidewalks and approximately 15,000 sq.m of green space. The "first stone" of this development was the deconstruction of the Gambetta viaduct. The engineering structure spanning the Boulevard Circulaire de La Défense linked Courbevoie to the business district. This road complex made it difficult and unreadable for pedestrians to use an underpass, "la fosse aux ours" (the bear pit), which was dark and unsightly.
From June 2004, the development of the Boulevard Circulaire de La Défense was taking shape. The Segoffin traffic light junction offers a new permeability, with level and safe pedestrian crossings, green spaces and the outline of the cycle path.
The Gambetta crossroads opens up a green corridor, "le Cours Gambetta", to pedestrians with relaxation areas embellished with a pool.
From the Neuilly bridge to the Folie crossroads in Puteaux, the first phase of development, completed in 2008, has achieved its objectives: making room for the car again to create gentle links, calming speeds, creating green spaces, and urban sewing by erasing the motorway "moat".
Concertations to make this boulevard more human and more urban
Paris La Défense has entrusted the Richez & Associés agency and the Artelia Ville et Transport design office with the task of developing this axis into a more urban and human boulevard, by encouraging mixed use on its outskirts.
Indeed, the operations of the Renewal Plan with the numerous tower projects in this part of La Défense have provided an opportunity to continue the reflection on the evolution of the Boulevard Circulaire. The objectives pursued are to rework the public spaces to facilitate connections between La Défense and the City of Courbevoie and to transform this former urban motorway into a genuine urban boulevard.
In summary, the main objectives of the consultation phase were :
- the continuous development of the boulevard along its length in order to achieve a real urban and landscape unit (homogeneous treatment of the soil, tree planting, lighting plan...)
- the creation of new transverse pathways (stairs, lifts, etc.) to provide a link between the town of Courbevoie and the La Défense slab
- the enhancement of the tower feet and the new programs that are being implemented there.
Paris La Défense has completely rehabilitated the circular boulevard of La Défense and its surroundings from the Pont de Neuilly to Avenue Gambetta in Courbevoie.
The redevelopment is nearing completion, in a completely rethought and renovated district.
New or renovated real estate programs have been delivered: the Eqho, Carpe Diem, D2, Blanche, Europe towers, the Mélia Paris La Défense hotel, and others will soon see the light of day: the Alto and Saint-Gobain towers.
- In the vicinity of the Carpe Diem tower, a monumental staircase now provides access to the La Défense slab from Courbevoie and the circular boulevard. The tower benefits from a taxi drop-off point, the "Marie Paradis" square. The Corolles car park has been renovated and modernised and the Place des Corolles redeveloped.
- The D2 tower benefits from many new developments: two engineering structures, the D2 "Frida Kahlo" square and the Corolles square "Annette Kellerman", were built from scratch; the Reflets 1 car park with 1,000 spaces has been completely modernized; the tower has its own local service; it is directly connected to the Place des Reflets on the one hand, and to the Place de l'Iris on the other, thanks to the creation of a staircase and the installation of a double elevator on the Alsace footbridge.
Paris La Défense carried out the development work at the same time as the tower. This concomitance of operations was made possible by the developer's implementation of site coordination measures ensuring rapid completion of the project (3 years) with a minimum of inconvenience and nuisance for local residents.
