After months of work, with many breaks in between mind you, I've just about completed my Interchange Rebuild Project.
Looper Junction, located in Dresden of the South Shores borough is where highways 700 & 702 meet and one of 7 major interchanges that needed to be completely rebuilt.
current Highway System map;
As with the others, the reason for rebuilding this interchange is because I decided to used the Project Symphony highway mod, which is not compatible with NAM highway interchanges. Looper Junction before the rebuild;
This was a rather difficult interchange to rebuild because of how the two highways met. I couldn't easily change the approaches of each highway without destroying a good portion of the city and extensive terrain modification. The lack of diagonal highway ramps for Project Symphony and elevated RHW additionally limited possible solutions. All of which necessitated a unique solution to fully connect the two highways.
My first attempt;
Not exactly very realistic or aesthetically pleasing.
Problem was the missing piece I needed to create the interchange I had in mind doesn't actually exist.
Then it hit me, why not just make it myself?
As for the name, I think its rather self explanatory as to why I settled on calling it Looper junction;
The missing piece;
Admittedly its not the safest interchange around since most of the ramps don't have extended merging lanes. To account for this speeds are heavily restricted on the ramps and the 700 approaching/departing downtown Dresden. And a center median was also built to prevent the most dangerous type of collision(head on's). But most importantly it is fully functional;
It's not as large or as free flowing as spaghetti junction but considering the circumstances, I think it came out alright;
