As you proceed into the tunnel, the most immediate feature is the ever-changing projection on the walls. These are not static images but curated loops that transform the concrete into various environments. …

Let us examine the technical prowess required to create this space. Boring a new tunnel alongside an existing, active roadway in a dense urban environment presented significant engineering challenges. …

As you walk, pay attention to the signage on the walls. The tunnel serves as a giant ruler, indicating exactly how far you are from the Saône and Rhône rivers. …

The dedicated lane for pedestrians and cyclists is a bold statement of Lyon's urban philosophy. In many cities, tunnels are hostile environments for anyone not in a car. …
