Sydney tunnel water screen stop sign for oversized...
I think they actually shut down the lights in the tunnel before the screen goes off. You can see it in the video when the lights go off and tunnel is suddenly much darker.

Probably not the whole tunnel, just the entrance to enhance the projection effect. Remember there is still traffic in the remainder of the tunnel.
