Super-8 4 way interchange + dogbone
Super-8 4 way interchange + dogbone highway entrance / exit
Turn a little city into a MEGA CITY. All directions can enter and exit from the dogbone. Very high density interchange can handle a huge city by itself.
Elevation goes from 0-18. Needs NE2 for 4 lane and 2 lane highways. Roundabouts are 10×10. Doesn’t need anarchy to place because the pillars are perfect. Reduced the number of nodes (for performance).
Shuto Expressway version. https://steamcommunity.com/sharedfiles/filedetails/?id=1881865854
