You can make a bridge out of a log and it stays up, doesn't it? You can do that with arches too.

So do our bridges! One island to one island!

A lot of biggest bridges are natural, too. The smallest islands can move around, but the districts are steady! You wouldn't know you were floating unless you went out to one of the ports to see the drop-off.
