Bridgewater Canal

The Bridgewater Canal connects Runcorn, Manchester and Leigh, in North West England. It was commissioned by Francis Egerton, 3rd Duke of Bridgewater, to transport coal from his mines in Worsley to Manchester. It was opened in 1761 from Worsley to Manchester, and later extended from Manchester to Runcorn, and then from Worsley to Leigh.

The canal is connected to the Manchester Ship Canal via a lock at Cornbrook; to the Rochdale Canal in Manchester; to the Trent and Mersey Canal at Preston Brook, southeast of Runcorn; and to the Leeds and Liverpool Canal at Leigh. It once connected with the River Mersey at Runcorn but has since been cut off by a slip road to the Silver Jubilee Bridge. Following the re-routing of roads to the Silver Jubilee Bridge, the Runcorn Locks Restoration Society campaigns to reinstate the flight of locks.

The Bridgewater Canal is described as the first great achievement of the canal age, although the Sankey Canal opened earlier. Bridgewater captured the public imagination because of its engineering feats; it required the construction of an aqueduct to cross the River Irwell, and a tunnel at Worsley. Its success helped inspire a period of intense canal building in Britain, known as Canal Mania. It later faced intense competition from the Liverpool and Manchester Railway and the Macclesfield Canal. Navigable throughout its history, it is one of the few canals in Britain not to have been nationalised, and remains privately owned. Pleasure craft now use the canal which forms part of the Cheshire Ring network of canals.

Design and construction

Francis Egerton, 3rd Duke of Bridgewater, owned some of the coal mines dug to supply North West England with fuel for the steam engines instrumental in powering England's Industrial Revolution. The duke transported his coal along the Mersey and Irwell Navigation and also by packhorse, but each method was inefficient and expensive; river transport was subject to the vagaries of river navigation, and the amount of coal packhorses could carry was limited by its relative weight. The duke's underground mines also suffered from persistent flooding, caused by the geology of the Middle Coal Measures, where the coal seam lies beneath a layer of permeable sandstone.

Having visited the Canal du Midi in France and watched the construction of the Sankey Canal in England, the duke's solution to these problems was to build an underground canal at Worsley, connected to a surface canal between Worsley and Salford. In addition to easing overland transport difficulties and providing drainage for his mines, an underground canal would provide a reliable source of water for the surface canal, and also eliminate the need to lift the coal to the surface (an expensive and difficult proposition). The canal boats would carry 30 LT at a time, pulled by only one horse – more than ten times the amount of cargo per horse that was possible with a cart. The duke and his estate manager John Gilbert produced a plan of the canal, and in 1759 obtained an act of Parliament, the (32 Geo. 2. c. 2 Pr.), enabling its construction.

James Brindley was brought in for his technical expertise (having previously installed a pumping system at the nearby Wet Earth Colliery), and after a six-day visit suggested varying the route of the proposed canal away from Salford, instead taking it across the River Irwell to Stretford and thereon into Manchester. This route would make connecting to any future canals much easier, and would also increase competition with the Mersey and Irwell Navigation company. Brindley moved into Worsley Old Hall and spent 46 days surveying the proposed route, which to cross the Irwell would require the construction of an aqueduct at Barton-upon-Irwell. At the duke's behest, in January 1760 Brindley also travelled to London to give evidence before a parliamentary committee. The duke therefore gained a second act of Parliament, the (33 Geo. 2. c. 2 Pr.), which superseded the original.

Brindley's planned route began at Worsley and passed southeast through Eccles, before turning south to cross the River Irwell on the Barton Aqueduct. From there it continued southeast along the edge of Trafford Park, and then east into Manchester. Although a connection with the Mersey and Irwell Navigation was included in the new act, at Hulme Locks in Castlefield (on land previously occupied by Hulme Hall), this was not completed until 1838. The terminus would be at Castlefield Basin, where the nearby River Medlock was to help supply the canal with water. Boats would unload their cargoes inside the duke's purpose-built warehouse. There were no locks in Brindley's design, demonstrating his ability as a competent engineer. The Barton Aqueduct was built relatively quickly for the time; work commenced in September 1760 and the first boat crossed on 17 July 1761.

The duke invested a large sum of money in the scheme. From Worsley to Manchester its construction cost £168,000 (equivalent to £ in), but its advantages over land and river transport meant that within a year of its opening in 1761, the price of coal in Manchester fell by about half. This success helped inspire a period of intense canal building, known as Canal Mania. Along with its stone aqueduct at Barton-upon-Irwell, the Bridgewater Canal was considered a major engineering achievement. One commentator wrote that when finished, "[the canal] will be the most extraordinary thing in the Kingdom, if not in Europe. The boats in some places are to go underground, and in other places over a navigable river, without communicating with its waters".

In addition to the duke's warehouse at Manchester, more buildings were built by Brindley and extended to Alport Street (now called Deansgate). The warehouses were of timber-frame design, with load-bearing hand-made brick walls, supported on cast iron posts. The duke's warehouse was badly damaged by fire in 1789 but was rebuilt.

Manchester to Runcorn extension

In September 1761, with his assistant Hugh Oldham, Brindley surveyed an extension from Longford Bridge to Hempstones, near Halton, Cheshire. He assisted in obtaining parliamentary approval for the (2 Geo. 3. c. 11 Pr.) which allowed the construction of an extension to the canal, from Manchester, to the River Mersey at Runcorn. Despite objections from the Mersey and Irwell Navigation Company, Royal assent was given on 24 March 1762. A junction, Waters Meeting, was created in Trafford Park, at which the new extension branched south through Stretford, Sale, Altrincham, Lymm and finally to Runcorn.

In December 1761 Brindley undertook a survey of the route at Runcorn. His initial plan was to make the terminus at Hempstones, east of Runcorn Gap, but following a study of the tides and depth of water there, he decided instead to build the terminus west of Runcorn Gap. This change was designed to accommodate Mersey flats, although the low fixed bridges required that traffic on the canal be able to lower or unship their masts. Runcorn basin was almost 90 ft above the Mersey, so a flight of ten locks, described as "the wonder of their time", was built to connect the two. Nine locks had a fall of 2 m, with a fall at the river lock of more than 6 m at low water. It allowed vessels to enter and leave the canal on any tide. The connection to the Mersey was made on 1 January 1773. The river's tidal action tended to deposit silt around the lower entrance to the locks, so to counteract this a channel, equipped with gates at each end and known as the Duke's Gut, was cut through the marshes upriver from the locks. At high tide the gates were closed, and with the ebb of the tide were opened to release water, which scoured the silt from the entrance to the locks. The cut created an island, known as Runcorn Island, crossed by Castle Bridge.

The connection to Manchester was delayed by Sir Richard Brooke of Norton Priory. Concerned that boatmen might poach his game and wildfowl, Brooke did not want the canal to pass through his land. The act included several stipulations: the canal should not come within 325 m of his house; the towpath should be on the south side of the canal, furthest away from Brooke's house; there should be no quays, buildings, hedges or fences to obstruct the view; no vessels were to be moored within 1000 m of the house, other than during construction. Eventually, though, a compromise was reached. This included the construction of a link to the Trent and Mersey Canal at Preston Brook (permitted by the Trent and Mersey Canal Act 1766), and the building of the canal's terminus to the west of Runcorn Gap. The Trent and Mersey link gave the Duke access to the Midlands, and forestalled the Weaver Trustees from making their own junction with the canal. The new extension also met with opposition from the Mersey and Irwell Navigation, until the duke purchased a controlling interest in the company. The first part of the new extension was opened in 1767, and completed in full by March 1776, but Brindley did not live to see its completion; it was continued by his brother-in-law, Hugh Henshall.

The total cost of the canal, from Worsley to Manchester and from Longford Bridge to the Mersey at Runcorn, was £220,000. Alongside the Mersey, the duke built Runcorn Dock, several warehouses, and Bridgewater House, a temporary home from which he could supervise operations at the Runcorn end. Two locks up from the tideway was a small dry dock.

Sale to Stockport branch

In 1766 the duke gained a fourth act of Parliament, the (6 Geo. 3. c. 17 Pr.) for a branch canal between Sale Moor and Stockport which was to follow the valley of the Mersey. The act was applied for to counter a proposed canal that would give the towns of Stockport and Macclesfield access to the Mersey, via the River Weaver. The work was not done, the act lapsed and this section of canal was never built.

Over two decades later, the nearby Manchester Bolton & Bury Canal had sought a connection to other waterways, and it appears that the duke had planned to limit the activities of the new company. On 15 December 1792 the duke purchased a portion of the Ringspiggot estate in Salford which blocked the MB&BC's plans to build a riverside basin and wharfs there.

Worsley to Leigh extension

In 1795 the duke secured a fifth act, the (35 Geo. 3. c. 44), which enabled him to extend the canal a further 5 mi from Worsley via Boothstown, Astley Green and Bedford to Leigh. The new extension enabled the supply to Manchester of coal from Leigh and the surrounding districts. On 21 June 1819 the Leeds and Liverpool Canal Branch and Railway Act 1819 (59 Geo. 3. c. cv) was enacted to create a link between this extension and the Leeds and Liverpool Canal at Wigan.

Access to the canal brought about a rapid development in coal mining on the Manchester Coalfield west of Worsley. Chaddock pits in the east of Tyldesley were connected to an underground level from Worsley. In 1820, to ease congestion at the Delph in Worsley, Chaddock Pit was connected to the canal at Boothstown basin by an underground canal, the Chaddock Level which ran in a north west direction from the canal at Boothstown to the pit. Sometime after 1840 Samuel Jackson built a narrow gauge tramroad worked by horses from his Gin Pit Colliery to Marsland Green where he installed cranes and tipplers to load barges at a wharf. The tramroad was later worked by locomotives. In 1867 the Fletchers built a private railway line and the Bedford Basin with facilities for loading coal from Howe Bridge onto barges. Astley Green Colliery began winding coal on the north bank of the canal in 1912. In the 1940s and '50s coal was sent to Barton Power Station and Runcorn Gas Works.

Connection to Rochdale Canal

Upon completion of the Rochdale Canal in 1804, the two canals were joined at Castlefield. This connection may have been a factor in the failure of the Manchester Bolton & Bury Canal Company's rival scheme to build a canal between Bury and Sladen. The River Medlock, a major source of water for the canal and which was almost as badly polluted as the nearby Irwell, was diverted through a tunnel under the canal at Castlefield by Charles Edward Cawley, a civil engineer for the Salford Corporation and later a Member of Parliament (MP) for Salford. The canal was from that point supplied by the much purer water of the Rochdale Canal.

Mines

Worsley Delph, in Worsley, originally a centuries-old sandstone quarry near Worsley Brook, was the entrance to the Navigable Levels. It is now a scheduled monument. Two entrances, built years apart, allow access to the specially built M-boats (also known as Starvationers), the largest of which could carry 12 LT of coal. Inside the mines 46 mi of underground canal on four levels, linked by inclined planes, were constructed. The mines ceased production in 1887. As the canal passes through Worsley, iron oxide from the mines has, for many years, stained the water bright orange. The removal of this colouration is currently the subject of a £2.5 million remedial scheme.

Traffic

In 1791 the mines at Worsley produced 100282 LT of coal, 60461 LT of which were "sold down the navigation"; 12000 LT of rocksalt was also transported from Cheshire. Sales of coal were £19,455, and nearly £30,000 was earned from other cargoes. Passenger traffic in 1791 brought in receipts of £3,781.

The canal also carried passengers and was in keen competition with the Mersey and Irwell Navigation Company (M&IN). The journey down river by the latter route took eight hours (nine hours in the up direction) while the journey on the Bridgewater Canal took nine hours each way. Fares were similar but the Bridgewater route was said to be "more picturesque". Boating men also used the canal. They lifted their small lightweight boats out of the M&IN at Runcorn, and carried them a short distance up the steep streets onto the Bridgewater Canal.
