are you sure about that? It was only just changed to construction back in May and the new temporary onramp added https://www.openstreetmap.org/way/1423785982/history.

Are you sure these are more recent changes than those made a years ago?

Also https://www.openstreetmap.org/way/1106729756 connects to the tunnel, which is still marked as underconstruction so you've just opened the onramp leading into a dead-end once you reach the tunnel. I think you might be mistaken?
