Barton Swing Aqueduct

I have messed about with this blip today to give it an 'olde worlde' look - as if the photo had been taken when the thing was built.

The thing is the Barton Swing Aqueduct that carries the Bridgewater Canal over the Manchester Ship Canal - and like it says on the tin, it swings 90 degrees to allow ships to get past.

A marvellous piece of engineering.
