Sorry I have been a bit remiss in posting anything.
We have been down to Worsley, lovely place and the wonderful Barton Swing Aqueduct.
The Barton Swing Aqueduct is the first and only swing aqueduct in the world. It carries the Bridgewater canal across the Manchester ship canal. It replaces the earlier unmovable aqueduct built as part of the original Bridgewater canal. The swinging action allows large vessels using the ship canal to pass underneath, the swing bridge opened in 1894 and remains in regular use .
I have uploaded a couple of videos to YouTube of it operating, we were lucky when we got there they had it open and we watched it close.
