Thank you. 
However, I checked it on the way home last night and there is no change. I therefore reverted your change just now.  
Note also that Google Maps seems to have taken your change as a signal, and since last week shows this bridge as open - it was marked closed there before.
Finally, if you follow the links referred to  in my original message (OSM notes and the 'note' key value on the bridge), it is clear that the bridge will not re-open for years.
