The increase in attendance at Don-Sainghin station has resulted in an endemic saturation of the facilities carried out by the MEL and, more generally, of public spaces nearby. It was in this context that the extension of the multimodal exchange hub of Don/Sainghin station was decided. This first phase of extension will be carried out on part of the existing relay park. The planned works concern, on the one hand, the construction of a light superstructure car park and, on the other hand, the reorganisation of the parking spaces on the ground following the removal of the knots under the influence of the new construction.
