​ Many bridges can damage and use a lot of space at their feet, while slowly inclining to allow water or other traffic underneath. Bystrup came up with a clever and simple solution: They coiled the necessary elevation gain into a spiral at each end, looping cyclists and walkers around a circular path that hangs from the suspension cables at each tower.

It will be interesting to see if this gets implemented, and to think how this could apply to Winnipeg's infrastructure.
