Geograph - photograph every grid square

Taken earlier this year from the ferry boat "Snowdrop" during a trip from Liverpool Pier to Salford Docks (highly recommended trip for Geograph members, lots of industrial archaeology). As can be seen the aqueduct is open to allow the ferry through, a lovely piece of late Victorian engineering still in operation today. More can be found in Wikipedia, extract from which is pasted below:-

The Barton Swing Aqueduct is a moveable navigable aqueduct in Barton upon Irwell in Greater Manchester, England. It carries the Bridgewater Canal across the Manchester Ship Canal. The swinging action allows large vessels using the ship canal to pass underneath and smaller narrowboats to cross over the top. The aqueduct, the first and only swing aqueduct in the world, is a Grade II* listed building, considered a major feat of Victorian civil engineering. Designed by Sir Edward Leader Williams and built by Andrew Handyside and Company of Derby, the swing bridge opened in 1894 and remains in regular use.
