Because thinking about Broadway: every time I use the underpass at Railway Square I feel like some sort of distance contraction is at play.

Arrows for non-Sydney people to show where the ramp leading up to Railway Square is located in the tunnel, and roughly where it emerges.

I find my brain can't quite reconcile how short the tunnel seems vs how wide the road.

I think it shows how the brain (correctly) perceives the 8 lanes of traffic like a dangerous gulf to avoid crossing at all costs.
