The Leeds and Liverpool Canal is a canal in Northern England, linking the cities of Leeds and Liverpool. Over a distance of 127 miles (204 km), it crosses the Pennines, and includes 91 locks on the main line. It has several small branches, and in the early 21st century a new link was constructed into the Liverpool docks system.

History
Background
In the mid-18th century the growing towns of Yorkshire including Leeds, Wakefield, and Bradford, were trading increasingly. While the Aire and Calder Navigation improved links to the east for Leeds, links to the west were limited. Bradford merchants wanted to increase the supply of limestone to make lime for mortar and agriculture using coal from Bradford’s collieries and to transport textiles to the Port of Liverpool. On the west coast, traders in the busy port of Liverpool wanted a cheap supply of coal for their shipping and manufacturing businesses and to tap the output from the industrial regions of Lancashire. Inspired by the effectiveness of the wholly artificial navigation, the Bridgewater Canal opened in 1759–60. A canal across the Pennines linking Liverpool and Hull (by means of the Aire and Calder Navigation) would have obvious trade benefits.

A public meeting took place at the Sun Inn in Bradford on 2 July 1766 to promote the building of such a canal. John Longbotham was engaged to survey a route. Two groups were set up to promote the scheme, one in Liverpool and one in Bradford. The Liverpool committee was unhappy with the route originally proposed, following the Ribble valley through Preston, considering that it ran too far to the north, missing key towns and the Wigan coalfield.

A counter-proposal was produced by John Eyes and Richard Melling, improved by P.P. Burdett, which was rejected by the Bradford committee as too expensive, mainly because of the valley crossing at Burnley. James Brindley was called in to arbitrate and ruled in favour of Longbotham’s more northerly route, though with a branch towards Wigan, a decision which caused some of the Lancashire backers to withdraw their support, and which was subsequently amended over the course of development.

An Act was passed in May 1770 authorising construction, and Brindley was appointed chief engineer and John Longbotham clerk of works; following Brindley’s death in 1772, Longbotham carried out both roles.

Construction
A commencement ceremony was held at Halsall, north of Liverpool on 5 November 1770, with the first sod being dug by the Hon. Charles Mordaunt of Halsall Hall. The first section of the canal opened from Bingley to Skipton in 1773. By 1774 the canal had been completed from Skipton to Shipley, including significant engineering features such as the Bingley Five Rise Locks, Bingley Three Rise Locks and the seven-arch aqueduct over the River Aire. Also completed was the branch to Bradford. On the western side, the section from Liverpool to Newburgh was dug. By the following year the Yorkshire end had been extended to Gargrave, and by 1777 the canal had joined the Aire and Calder Navigation in Leeds.

On the western side it reached Wigan by 1781, replacing the earlier and unsatisfactory Douglas Navigation. By now, the subscribed funds and further borrowing had all been spent and work stopped in 1781 with the completion of the Rufford Branch from Burscough to the River Douglas at Tarleton. The war in the American colonies and its aftermath made it impossible to continue for more than a decade.

In 1789 Robert Whitworth developed fresh proposals to vary the line of the remaining part of the canal, including a tunnel at Foulridge, lowering the proposed summit level by 40 feet, and a more southerly route in Lancashire. These proposals were authorised by a fresh Act in 1790, together with further fund-raising, and in 1791, construction of the canal finally recommenced south-westward from Gargrave, heading toward Barrowford in Lancashire.

In 1794 an agreement was reached with the Manchester, Bolton and Bury Canal company to create a link near Red Moss near Horwich. However by this time, the competing Rochdale Canal had begun construction and was likely to offer a more direct journey to Liverpool via Manchester and the Bridgewater Canal. The company’s experiences running the two sections of the canal had also shown that coal, not limestone, would be its main cargo, and that there was plenty of income available from local trade between the settlements along the route.

With this in mind in the same year, the route was changed again with a further Act, moving closer to that proposed by Burdett and the planned canal link did not materialize. Yet more fund-raising took place, as the Foulridge Tunnel was proving difficult and expensive to dig. The new route took the canal south via the expanding coal mines at Burnley, Accrington and Blackburn, but would require some sizable earthworks to pass the former. The completion in 1796 of the 1,640 yards (1,500 m) long Foulridge Tunnel and the flight of seven locks at Barrowford enabled the canal to open to eastern Burnley.

At Burnley, rather than using two sets of locks to cross the shallow Calder valley, Whitworth designed a 1,350 yards (1,234 m) long and up to 60 feet (18 m) high, embankment. It would also require a 559 yards (511 m) tunnel nearby at Gannow and a sizeable cutting to allow the canal to traverse the hillside between the two. It took 5 years to complete this work, with the embankment alone costing £22,000.

Once completed, the canal opened to Enfield near Accrington in 1801. It would be another 9 years until it reached Blackburn only 4 miles away. Following the French Revolution, Britain had been at war with France from 1793 to 1802. The peace proved temporary, with the Napoleonic Wars beginning the following year. High taxes and interest rates during this period made it difficult for the company to borrow money, and the pace of construction inevitably slowed.

The Manchester, Bolton and Bury Canal company proposed another link from Bury to Accrington. This new link would have been known as the Haslingden Canal. The Peel family asked the canal company not to construct the crossing over the River Hyndburn above their textile printworks; such a crossing would have required the construction of embankments, and reduced the water supply to their factories. Consequently Accrington was bypassed and the Haslingden Canal was never built.

The latest plan for the route had it running parallel to, and then crossing the isolated southern end of the Lancaster Canal, but common sense prevailed and the Leeds and Liverpool connected with the Lancaster Canal between Wigan and Johnson’s Hillock. The main line of the canal was thus completed in 1816.

There had been various unsuccessful negotiations to connect the canal to the Bridgewater Canal at Leigh but agreement was finally reached in 1818, and the connection was opened in 1820, thus giving access to Manchester and the rest of the canal network. The Bridgewater Canal, like most of Brindley’s designs was for narrow boats of 72 feet (22 m) length, whereas the Leeds and Liverpool had been designed for broad boats of 62 feet (19 m) length. There was naturally a desire by the narrow boats to reach Liverpool and the locks of the westerly end of the canal were extended to 72 feet (22 m) in 1822.

Operation
The canal took almost 40 years to complete, in crossing the Pennines the Leeds and Liverpool had been beaten by the Huddersfield Narrow Canal and the Rochdale Canal. The most important cargo was always coal, with over a million tons per year being delivered to Liverpool in the 1860s, with smaller amounts exported via the old Douglas Navigation. Even in Yorkshire, more coal was carried than limestone. Once the canal was fully open, receipts for carrying merchandise matched those of coal. The heavy industry along its route, together with the decision to build the canal with broad locks, ensured that (unlike the other two trans-Pennine canals) the Leeds and Liverpool competed successfully with the railways throughout the 19th century and remained open through the 20th century.
