Bridges over (perhaps troubled, depending on the rebel threat in Tropico) water are great, and extremely useful, as are tunnels for going underneath mountains, and teleferic stations for getting people up cliffs from a lower altitude, and cargo airports for doing the same for cargo. But... In some cases (on randomly generated maps), tunnels will not be able to connect because "terrain is too uneven" or "tunnel is not underground."

Random maps are great, they're fun, and they're extremely versatile. But they're also very annoying, because sometimes Tropico 6 generates a double-height plateau and no way to get teamsters or construction workers up there. Infuriating, especially when there's 1.6 MILLION IRON (2 deposits of 800,000) right on that plateau, ripe for the taking.

So, how would this be done (ignoring the cargo airport)? I have a few ideas.
-Ramps. Keep it simple, stupid. Just a bridge that you start from far-ish away and gently inclines up to the desired height so that teamster trucks could realistically make that trip without deciding to stall and maybe even fire backwards, resulting in one forward speed and twelve reverse speeds if Tropico uses two stroke diesels. Or it could be a pile of concrete, but that's kind of boring.
-Teamsterferic station. That's it. Cable cars with cargo space alongside passenger space.
-Conveyors (as a precursor of sorts to the cargo cable cars). Because conveyors are cool and usually reliable.
-Teamster Locks. Ship go up, ship get loaded, then ship go down. Tropico's locks could be capable of being unrealistically tall for the lulz.

Feel free to add your own!
