I took a picture from the west end: https://photos.app.goo.gl/brdET1sqyRF6rcWL9

I don't recall if there was any prohibition, but I don't think it's passable by anything except mountainbikes and hikers. OsmAnd had routed us through this, but with heavily loaded touring bikes we had to detour all the way north to the D36C.

I'm not sure how to best represent the MTB/touring distinction though. If you figure the current state is correct, please feel free to resolve.
