BTW ran into some annoying infrastructure things just now.
- You can only have up to 8 ramps (I assume bridges have the same arbitrary limit)
- It takes a full day to destroy a ramp or bridge, and you can't start a new project during this time

- It costs 10k bells to destroy a ramp or bridge (the 180k to build it wasn't enough?)
