The Leeds-Liverpool canal is the longest canal in the North of England at one hundred and twenty seven miles and has a total of ninety one locks. The first section of the canal was opened in seventeen seventy three but it was another forty six years before the canal was fully completed and the cost was five times the original estimate. This two-rise staircase lock is at Apperley Bridge and was completed in seventeen seventy seven and is now a Grade II listed structure. The boat in the picture is much wider than the usual boats, I think it is referred to as 'wide beam' which limits the canals it can be used on, many of the canals in the UK are much narrower and can only take 'narrowboats'.
