I live near a mixed use cycle+pedestrian underpass under a railroad that has curves into and out of it. It's mildy terrifying in a way that's surely by design.

I live near a mixed use cycle+pedestrian underpass under a railroad that has curves into and out of it. It's mildy terrifying in a way that's surely by design. I don't know how safe it actually is, but it _is_ used very heavily - because it's by far the shortest path connecting most routes on the opposite sides of the train track, which trumps virtually all other concerns in day to day traffic, especially for pedestrians and cyclists. And hey, there's no car traffic, so accidents are likely to be at least a little milder, though hitting one of those stone pillars is perhaps not much better.
