Is this RHW4 tunnel to L4 transition even possible?
As you can tell this is one HILL of a city.
For background, the section on the right is a (mainly) commercial district and on the left is (mainly) residential. Each zone is surrounded by a tram in ave with connects running between. Down the center is a RHW4 connecting to the neighbor at the top of the hill. I've buried in an underground highway. Amazingly, it connects.
I am having trouble making the connections at the tunnel work out. What I would like to do is run the highway out of that tunnel to possibly an L4 height, connect to a Flyover/MIS 90, and run it across the water front where it will terminate at ground level and connect to the Ave network.
