CIMA+ carried out the complete reconstruction of the pavement, waterworks and sewer systems over a distance of 1,250 m on a street lined with 300-year-old buildings. This presented a significant challenge due to the value of this heritage site that needed to be protected. The project included landscaping, installation of functional and atmosphere lighting systems, separation of combined sewers into domestic and stormwater sewers, and the replacement of the emissary located on top of the cliff.
