Underground belts that go under other underground belts. Of course, digging that far down requires more reinforcement, so you have to use some concrete and iron rods to craft them. Spaghettify even harder! Go mad with power!

Support is included for Space Age, Bob's Logistics, and Krastorio 2. I might add support for other mods that add new belts as well.

TODO: make good graphics. should the above ground parts look different? definitely need an icon for the technology though
