On the surface, at every intersection: stops, red lights, slowdowns, and that familiar accordion effect that turns a smooth trip into a jerky one.

Underground, we have an asset the surface doesn't: depth. At every crossing of the network, one tunnel simply passes beneath the other.

  • No stops
  • No traffic lights
  • No accordion effect
  • 100% continuous traffic, 24 hours a day

From Sainte-Foy to Old Québec without setting foot on the ground a single time. Smooth, steady, predictable pedalling — like a river that never meets a dam.

An underground interchange: tunnels weave across several levels without ever cutting into each other.

Key takeaway: the surface is saturated — beneath our feet, space is infinite. That's the magic of thinking in 3D.
