The first column shows how a trailblazer would look just after the interchange. It follows the road eastbound or northbound, although it may not be signed that way at that point.

The second column shows how the exit sign on the freeway approaching the interchange will look. Click on the arrow or EXIT ONLY to exit (only if I have an exit list for the connecting road).

The third column is color-coded for how the road is. Green means it's a full freeway thru the interchange (no cross traffic). Yellow means there is cross traffic. Red means the exit is closed. Sometimes there is a different color in opposite directions.

The fourth and fifth columns mirror the first and second for traffic going the other way.

The sixth column is the type of interchange and other notes. Any directions are relative to the major direction of the freeway, not neccesarily compass direction. Here are the interchange types that differ from Kurumi's field guide:
A road between is what Kurumi calls a folded diamond. I give the quadrants the ramps are in.
An extended trumpet is AKA a half folded diamond, the third of the 4-ramp parclos shown. I give the quadrant of the leaf (loop ramp).
In parclos I name which quadrants have leaves.
A Y is AKA a merge or split. A 3Y is what Kurumi calls a directional OR semidirectional T. Which one it is can be figured out from which lane the exit goes from.

Recently I have been adding maps in the last column. Bridges are green.
