The River Weaver is a river, navigable in its lower reaches, running in a curving route anti-clockwise across west Cheshire, northern England. Improvements to the river to make it navigable were authorised in 1720 and the work, which included eleven locks, was completed in 1732. An unusual clause in the enabling Act of Parliament stipulated that profits should be given to the County of Cheshire for the improvement of roads and bridges, but the navigation was not initially profitable, and it was 1775 before the first payments were made. Trade continued to rise, and by 1845, over £500,000 had been given to the county.

The Manchester Ship Canal is a 36 mi-long (58 km) inland waterway in the North West of England linking Manchester to the Irish Sea. Starting at the Mersey Estuary at Eastham, near Ellesmere Port, Cheshire, it generally follows the original routes of the rivers Mersey and Irwell through the historic counties of Cheshire and Lancashire. Several sets of locks lift vessels about 60 ft (18 m) to the canal's terminus in Manchester. Landmarks along its route include the Barton Swing Aqueduct, the world's only swing aqueduct, and Trafford Park, the world's first planned industrial estate and still the largest in Europe.
