A7 motorway / Boulevard du Général Leclerc footbridges

Marseille

Move back the A7 motorway by integrating its flow as from the Boulevard du Général Leclerc, construct a two level ring road bypassing Marseille’s city centre and incorporate the tunnel programmed to pass under the Saint-Charles main line station, preserve local traffic routes and privilege the pedestrian paths that, until now, had been completely neglected, reconcile districts fragmented by the motorway... These are just some of the challenges faced by the A7-Leclerc project.
The topography of the sector (10 metres height difference between Place Victor Hugo and Place Marceau) was a determining factor. Two city and urban access levels have been identified and connected by symmetrically laid out squares and transparent glass brick walkways, as well as ramps and staircases linked by a Corten® ribbon cut out around the public space. Each level has its own urban profile, pavements and differentiated access routes to the neighbouring buildings.
Resulting from the impact of the A7 motorway flyover as it enters Marseille and by the excavation of the Butte des Treize Escaliers hill, the rehabilitation of the walkway frees two platforms providing views over two of Marseille’s symbolic monuments – Notre-Dame-de-la-Garde and the Porte d’Aix gateway – and links the districts to the north of the city to the Porte d’Aix gateway and the station through a new interpretation of what city life should be.
