About This File
Based on Al Safa by agusingnavy. http://community.simtropolis.com/files/file/30529-al-safa-interchange/
In the screenshot with two interchanges, my first attempt at a 4 highway intersection with each highway exiting to the other 3 is on the right. I started by basing it off of http://thumbs.dreamstime.com/z/highway-interchange-guangzhou-dusk-modern-city-skyline-48932634.jpg. Unfortunately, I did not notice it lacks the number of connections I wanted and had to improvise and it was in-game instead of the much easier editor.
I took another look through some mods and found one that actually had all exits on this site here, http://community.simtropolis.com/files/file/30529-al-safa-interchange/. While I like the work done on this one and the idea of it, a few things stood out to me that just did not fit well and appear to be a result of the mods used to make it. For example, a few of the earthwork ramp to suspended ramp sections have dark shadows/lines through them and the street lights clip through the lower, outside, raised lanes as you can see in another screenshot.
Since I liked agusingnavy's idea I decided to try cleaning it up and without mods, made a smaller version based on that same design. You can see the result in the editor snapshot and the pic of the 2 interchanges together it's on the left. The last pic shows a size comparison as I laid it over agusingnavy's. As you can see it is slightly smaller in all dimensions, except height as I had to raise the outer lanes since I had slightly less room in the middle to go under and did not use the No-Pillars mod. It is also cheaper by almost 10k.
This is my first asset and upload. I started off by measuring to the center of each side by placing 2 6-lane roads to get the zoning squares to save my place then added 2 strips of highway directly next to the zoning edge near the middle. Then counted 2 full squares in the middle between where the actual highways were to go. Added the long, straight parts first after the main highways, had to use some placeholder lanes going the wrong way since it was hard to work off certain sides. I went back and forth trying to do the exact same thing on each side as I went.
I checked to see if there were any files with a similar name and did not see any so if I need to change anything please let me know. Again, credit to agusingnavy, I used his pics to build this version. Enjoy.
