Even with the ammo production, it can barely keep up. If the trip was any longer, the ship probably wouldn’t survive.

As far as I understand it, the node is more useful for car routing, since it marks the exact point on the road where the intersection crosses, while the way is more useful for pedestrian routing, where the actual path to be traveled is more relevant. I agree that it seems redundant, but for all I know, car routers might totally ignore any pedestrian footways, which would prevent them from filling in the crossing data on the fly.

Whenever I am building larger structures, I find it helpful to design smaller modular pieces that can fit together to make a larger structure. Maybe you can start with the corners to find a good way to outline the building, and then come up with some variations of tiling wall segments that you can repeat 3 or 4 times across the width of the building. Here are some examples of larger builds from my vanilla world that are just a few modular pieces put together into a larger structure:
