Today 28/05/2018 I walked a circular route from Acton Bridge station around part of the Weaver Navigation. This is an area I've seen many times from trains travelling over Dutton Viaduct.
The Weaver is Cheshire's main river, some 50 miles long. The lower section, from Winsford to the River Mersey, was made navigable in 1732 for the salt trade. The navigation channel has changed many times over the years to suit larger boats.
Dutton Viaduct was built in 1836 to carry the Grand Junction Railway (Birmingham to Warrington). When Dutton Locks were built in the 1870s the resulting change in routing caused the navigation to pass through different arches of the viaduct.
