Yes, Faldage. The northernmost part of your map is very much like what happens in the area that is a suicide merge. One road goes beneath the interstate, however, and the other one ramps off the interstate directly. I'll try to link up.

The ramps are where you see the northernmost green 54. If I take the ramp that goes southwest off exit 54 as you read the map, the other ramp becomes a small access road that merges with the southwest ramp--and it's a bear. A suicidal bear. Now, is there a term for such a mess of a merge?

Early Morning Edit: Oh, and by the way, Faldage, your graphics are just amazing.
