Municipal Council of Aix-en-Provence – Grassie footbridge

In order to better serve the School of the Nativity, which is situated at the end of a cul-de-sac immediately next to the Arc river, the townhall wished to build a footbridge to enable the Arc to be crossed. The footbridge is extended by an aerial path of over 100 metres which links the school to the schooling car park on the other riverbank. The footbridge is located in the area known as “domaine de la Grassie” and was built at the same time as the school car parking and the seven residential buildings.

The footbridge was constructed at the same time and in the same area as the construction of seven residential buildings and a car park. These interactions made the management of the activities more complex.

  • 40 metre footbridge extended by a 100-metre aerial path
