Croix-Rousse tunnel, 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 constructed, dedicated to pedestrian, cyclist and bus traffic.
