Historic evolution of the canal landscape, avoiding the necessity for locks. Dutton Stop Lock is the exception as this was Josiah Wedgewood was convinced that a system designed to restrict the flow of water from the of inland navigation would provide a cheaper and more efficient means of transporting goods and Trent and Mersey Canal into the Bridgewater Canal. Although essentially a ‘contour canal’, this raw materials than roads. With his financial section contains three tunnels (Barnton 572 yards support, James Brindley began to survey a route for a “Grand Trunk Canal” to join the rivers Trent (523 metres), Saltersford 424 yards (388 metres) and Preston Brook 1,239 yards (1,133 metres)). and Mersey in 1758. The section of the Trent and Mersey Canal Wedgewood promoted “The Navigation from the between Middlewich and Preston Brook was Trent to the Mersey Act” which was passed on originally intended as a wide canal, allowing boats the 14th May 1766 and work began soon after, (Flats) of 14 feet (4.25 metres) beam to come with James Brindley as surveyor-general to the from Liverpool and Manchester, and unload onto canal company. Upon Brindley’s death in 1772 he narrow boats at Middlewich. The bridges in this was succeeded by Hugh Henshall, previously Clerk section were built wide enough for the Flats. of Works, who completed the construction of the However, the tunnels between Barnton and canal.

The Trent and Mersey Canal was finally opened in The Flats still had to unload onto narrow boats 1777, covering a total length of 93 miles (150 km at Preston Brook. approx.) from Derwent Mouth on the River Trent to Preston Brook on the Bridgewater Canal. It was heavily used for sixty years, being the only good transport link between the Midlands, Manchester and Liverpool. Subsequent canal development created the “Grand Cross” system which by 1790 allowed the transportation of pottery, coal and salt between the rivers Trent, Mersey, Severn and Thames. This was an important element in industrial and transport evolution. Gradually commercial traffic on the canal declined, mainly because of competition from the railways and roads. By the early 1960’s commercial traffic was minimal, however this decline has been compensated by the growing interest in boating as a leisure activity. 1.3 Influence of land uses The Trent and Mersey Canal was nationalised in The impact of the salt industry on this section of 1948, and on 1st January 1963 came under the the canal is considerable.

Form and structure of the canal 3.3 Spaces 3.1 Conservation Area Boundary The nature of the canal means that spacially, it is predominantly linear in character, although along The boundary of the Conservation Area has been the length of the canal, important spaces have drawn tightly along the canal corridor. Generally, been created where the canal widens to field boundaries and hedgerows, especially along incorporate basins and wharves. The principle the towpath, define its extent for the majority of examples are the basins at Anderton and Barnton, its length. Significant areas of woodland adjacent the wide between Barnton and Saltersford to the canal are also included.

Even today, many pleasure craft are too long to turn in the width of the canal.

It is now difficult to see the old line, since it collapsed as expected, six months after the new section was opened. Along the length of the Conservation Area it is possible to identify three distinct character areas: Croxton Aqueduct to the A556 near Broken Cross; Broken Cross to Barnton; and Barnton to Preston Brook tunnel. 3.5.1 Croxton Aqueduct to Broken Cross This section begins where the canal crosses the River Dane by means of the Croxton Aqueduct. The canal parallels the river, north along the The wharf at Broken Cross was developed as a eastern side of the Dane valley, until Whatcroft general goods wharf for Northwich, due to Hall where it turns eastwards before continuing difficulties in completing the canal in the Barnton northwards to Broken Cross.
