Ok, sorry.

The roundabout is This is part of the motorway link that connects the who motorways.

Reverting this you are spliting motorway_link juntion.

Follow-up: changeset/180911769

This way is 3m wide and a normal offroad vehicle can reach the viewpoint, except for the point marked with note/5231947. At this point, a regular 4x4 vehicle only can pass bridging with recovery boards.

The track way/613327732 is transitable with vehicle with some high clearance without a heavy offroad vehicle except for the point marked by the note note/5231947.

Ops, thanks. I fixed it via changeset/173830524

Why you removed historic=monument tag?

Sorry I mean a traffic island instead of median.

If I remember correctly there are two ways separated by median, one to turn right and the other to straight forward.

If I remember correclty, there are two lanes (mapped as two ways), one to turn right an the other to straight forward.
