I'm not a very experienced ice skater, but it seems like the flatness of a frozen canal is what makes it nice to skate on. The renderings in the article show frozen over sidewalks, which presumably have at least small slopes to them. Would that make it to challenging to skate long distances? As a side note, I live in Washington DC where we've had a few weeks of sub-freezing temps, and was out on the frozen C&O canal last weekend. Unfortunately our canal doesn't go anywhere interesting, so it wouldn't make much of a commuter trail.
