I saw a bunch of Mountain Recreation Park Bridges. So maybe this is OK.

Six levels of stream waterfall mist plateaus. A hydrant running at the top. They're like volcanoes in a Zion in the sky or Goonies™ Cavern! I think if you platform dive into the Bugs Bunny made lakes, then you're going to have to jump off the railings forty some odd feet high! A Bugs Bunny made outsides building. I'm only kidding.

Downstairs is at the top. You want the outside lane all the way up the five of these. It's a tower of parks on bridges. NO BALLS OUT! They could fall down all the way.
