Croix-Rousse tunnel, Lyon

Delivery date: 2014 - Client: Grand Lyon


An essential link between the east and west of Lyon, this single-tube dual-carriageway tunnel carries urban traffic totalling 47,000 vehicles/day.
In addition to the major renovation work to bring the 1750-metre tunnel up to standard, a second tunnel was cut, dedicated to “soft” modes of transport (pedestrians, cyclists and electric buses).
