The development of the Lac Bleu aisle will take into account stormwater management and the renovation of the lighting network. The project also includes the implementation of effective road safety (high pedestrian crossing, horizontal and vertical signage, etc.). The planned road works therefore include the following elements: Construction of pavement structures (geotextile, GNT), realisation of car parks, sidewalks and cycle paths, laying of edges and rigs, realisation of coverings (dresses, bilayers, concretes...), realisation of floor markings and vertical signage,
