Creation of a multimodal traffic axis, known as the North-South axis, within the strategic Grand Arénas sector between Nice Airport and Grenoble Road. This axis makes it possible to structure the Nice Aéroport Multimodal Exchange Pole and to connect public transport facilities and soft modes. Background: the Lower Var Valley sector is a strategic urban development hub where several structuring projects are planned, including the Grand Arénas sector. Its development is based on the realisation of two important equipment: the Nice Aéroport multimodal exchange hub and an exhibition centre.
