With community interest in C:S suddenly back, that means "interest" in my spaghetti ramps are back. I present to you a 10 picture guide on creating your own spaghetti interchange. Difficulty: very easy!
1) Pick out a boring old interchange to upgrade. We're going to upgrade this one into a 5 way junction.
2) Clean out the area, in this case I'm just moving the railroad tracks. Then, lay out the "approach", where the highways will be on the leadup.
3) Connect the highway stubs together however you desire.
4) Time to start with the ramps! To make it simplest for us to make sure every direction is covered, I do one freeway direction at a time. After creating the ramps make sure that the initial direction can head into n-1 (in our case, 4) different directions! We'll start with the east to west route.
At this point it's usually easiest to do the flyovers since there isn't much in the way. It's easier to wiggle things around on the ground later on to avoid support pillars.
5) Now we'll do west to east.
Due to the nature of our junction, I'm able to only have one ramp into the northerly direction.
6) Now is south east to north.
It's usually at this point that tunnels become necessary. Also note the ramp for the northbound to westbound, it can be used for both oncoming freeways. When doing this I made sure to leave plenty of space for merging to avoid for traffic calamity there.
7) Now for south west to north.
When possible I try to avoid too many junctions on the main highways themselves. I prefer to have them on the ramps, as you can see I did with the northbound to westbound ramp on the middle right.
8 ) And lastly, south bound.
Because of the type of junction, as long as I have all of the exits prior to the split, I only need one ramp for each. You might notice the new and ridiculous flyover heading into the west. Yes, that's a 4th level bridge. yes, that's the highest I've ever done. yes, normally that would be a tunnel. I just wanted to do something fun and new
9) The junction in its full spaghetti glory
10) We're not quite done yet. While the junction looks absolutely awe inspiring regularly, it needs to be spruced up a little.
