Barton Swing Bridge
Four miles west of Manchester, between Stretford and Worsley, is one of the wonders of the waterway world - the Barton Swing Aqueduct, carrying the Bridgewater Canal across the Manchester Ship Canal.
This route of the Bridgewater Canal between the coal mines at Worsley and the centre of Manchester needed no locks but involved the construction in 1761 of an aqueduct across the River Irwell at Barton (which was, at that time, part of the Mersey and Irwell Navigation). No aqueduct on this scale had previously been constructed in England and critics thought it would never hold water. The canal was carried on high embankments and across the river, 38 feet below, on three sandstone arches
