Tour the world and watch it fall down

I love the sound of 10-15g waves slamming into the bridge.  I'd love to go and
stand on top of it.  It would be like a roller coaster ride for free, unless
it happened to give way just at that moment.  Then it would be an amazing ride,
but it wouldn't last long enough :)

Does anyone know of other 'poorly considered engineering decisions'?  It'd make
a great theme for an overseas tour.
