Okay, maybe I'm an idiot who can't search properly, maybe I'm not, but I've searched all over the forums, Google, etc., and I haven't found a definitive answer on a few nagging issues that I'm having with my city.
1) Is there anything in NAM or related mods that would let me add 30 or 60-degree roadways?
2) Is there anything available for underground avenues/highways?
3) For that matter, is there a good way to set up an underwater two-lane tunnel without massive terraforming?
If someone tells me to RTFM, I would just like to know which manual, since I've read all that I've found, and come up completely emtpy-handed.
Thanks in advance!
