why not have have a birdge somewhere maybe so bigger vehicles can get across like tanks and stuff
*bridge
interstellar is peak 
i think a more fun solution is making the buildings slightly closer to eachother and add a quick conveyor on the ramps since a bridge would look out of place
or we could scrap this whole idea and blend to the environment a scaffolding instead of a bridge for the heavier vehicles to drive on
Or maybe simply add a third one
maybe
miner spelling mistayke
actually now that i think about it tank battle would work really well
cuz if its like last 2 standing instead of them ramming into eachother they can just run and shoot at eachother idfk
One on each rooftop
