Ah, ok. That's new compared to StreetView on the road itself (from '08) where there is no such signage. Plus if you can get the photo log to turn around, you can see the '0MM' on the other side of that ESM pole.
Then again, back in '08, looks like that 'End State Maintenance' sign was closer to Brandenburg Station Road.
