This is a set of building blocks that allows you to create big industry zones with 2 cargo stations.
The whole point of this collection, is to easily build effective industry zones.

Collection consists of 6 segments, which should easily be joined together, just like Lego blocks.

Follow the picture. Start with IN-MID, then IN-A on one side and IN-B on the other side. Extend IN-A by building 4L one way road (straight 180 degrees). When you're satisfied with length, finish it with OUT-A. Connect OUT-A with OUT-MID. Build a 2L one way road for MID sections, they should fit straight. Connect OUT-B with OUT-MID. Fill in the roads.
Now you can add additional A sections or B sections. They should connect eaisly.

Train tracks. Can't seem to find good position for going undeground, manual edit is required. Will work on that later on.

Q: Why 4 lanes?
A: It's designed to be used with TrafficManager mod. Far left and far right lane should be switched off on the exit. That way all delivering trucks will use those lanes and all leaving ones will use middle lanes.
