Do suspension bridges still work when built this way? Those pilings look much easier to sway to me. Maybe they are just buried a little more securely. [[Special:Contributions/172.68.55.80|172.68.55.80]] 22:48, 7 February 2025 (UTC)

:Yep! With "classic" suspension bridges (like the Golden Gate Bridge), there is no fixed connection between the deck and the towers. With differring loads and temperatures the deck can move up and down about 30cm at tower level (and almost 2 netres at midpoint). Some modern bridges do ise a fixed connection or hinge between deck and tower. [[User:IIVQ|IIVQ]] ([[User talk:IIVQ|talk]]) 12:58, 8 February 2025 (UTC)

What if a car doing one of the fun jumps lands on a car that didn't do a fun jump? Should we mandate that every car does a fun jump for this reason (and yay, fun jump!)? 198.41.227.115 22:08, 7 February 2025 (UTC)

Radar speed management, vehicles are only let on the bridge if their expected land point is between the vehicles around them. 172.68.55.80 22:48, 7 February 2025 (UTC)
Carrot/stick question. If they do a jump, they get their toll refunded on the far side of the bridge. Maybe give them double refund if they do a flip. 172.69.246.135 04:07, 8 February 2025 (UTC)

This exact proposal, the 'dangling road', is actually The Meta in Poly Bridge 2. Poly Bridge 3 tried to tweak the numbers to make this strat less effective, but a variant of it continues to persist to this day. (This probably goes in the trivia section, because it seems like Randall came to this concept from first principles.) 172.71.151.65 01:07, 8 February 2025 (UTC)

It's funny to me, there's a level in Jak II for the PS2 that's literally just this idea: for whatever reason the city's central palace is held up by five suspension bridge-esque wires, and one level has you crawling along wire #4 to get inside the palace (the catch? The wires are covered in security robots) 172.71.159.7 01:54, 8 February 2025 (UTC)

I like the fact that vehicles are clearly on flexible cables, not some rigid material formed into a catenary shape. There's a truck between the two towers that is visibly depressing the cable it's riding. Nitpicking (talk) 03:57, 8 February 2025 (UTC)

Happy happy joy joy. No dogs allowed on this bridge. 162.158.42.87 04:35, 8 February 2025 (UTC)
