Old Canyon set I made. Large roads. Originally on Maniapark, then I took it down because there were issues with the items, decided it was too much work to fix, and never reuploaded.
Said issues are still present, but if you don't mind very minor gaps in a few places, have fun with these!
Also the tunnel items are designed to be placed inside the normal tunnel blocks, since that was the only way I could get light into them.
