The Kennet and Avon Canal is a waterway in southern England with an overall length of , made up of two lengths of navigable river linked by a canal. The name is used to refer to the entire length of the navigation rather than solely to the central canal section. From Bristol to Bath the waterway follows the natural course of the River Avon before the canal links it to the River Kennet at Newbury, and from there to Reading on the River Thames. In all, the waterway incorporates 105 locks.
The two river stretches were made navigable in the early 18th century, and the canal section was constructed between 1794 and 1810. In the late 19th and early 20th centuries, the canal gradually fell into disuse after the opening of the Great Western Railway. In the latter half of the 20th century the canal was restored in stages, largely by volunteers. After decades of dereliction and much restoration work, it was fully reopened in 1990. The Kennet and Avon Canal has been developed as a popular heritage tourism destination for boating, canoeing, fishing, walking and cycling, and is also important for wildlife conservation.
History
Early plans
The idea of an east-to-west waterway link across southern England was first mentioned in Elizabethan times, between 1558 and 1603, to take advantage of the proximity of tributaries of the rivers Avon and Thames, only apart at their closest. Later, around 1626, Henry Briggs made a survey of the two rivers and noted that the land between them was level and easy to dig. He proposed a canal to connect them, but following his death in 1630 the plan was dropped. After the English Civil War four bills were presented to parliament, but all failed after opposition from gentry, farmers and traders worried about cheaper water transport reducing the value of fees on turnpike roads they controlled, and cheaper produce from Wales undercutting locally produced food.
The main alternative to road transport for the carriage of goods between Bristol and London was a hazardous sea route through the English Channel. The small coastal sailing ships of the day were often damaged by Atlantic storms, and risked being attacked by warships of the French Navy and privateers during a succession of conflicts with France.
River navigations
Plans for a waterway were shelved until the early 18th century. However, in 1715, work was authorised to make the River Kennet navigable from Reading to Newbury. Work commenced in 1718, under the supervision of surveyor and engineer John Hore of Newbury. In 1723, despite considerable local opposition, the Kennet Navigation opened, comprising stretches of natural riverbed alternating with of artificially created lock cuts.
The River Avon had historically been navigable from Bristol to Bath, but construction of watermills on the river in the early years of the 13th century had forced its closure. In 1727, navigation was restored, with the construction of six locks, again under the supervision of John Hore. The first cargo of "Deal boards, Pig-Lead and Meal" reached Bath in December.
The two river navigations were built independently of one another, in order to meet local needs, but they eventually led to plans to connect them and form a through route.
Closing the gap
In 1788 a "Western Canal" was proposed to improve trade and communication links to towns such as Hungerford, Marlborough, Calne, Chippenham and Melksham. The following year the engineers Barns, Simcock and Weston submitted a proposed route for this canal, although there were doubts about the adequacy of the water supply. The name was changed from Western Canal to Kennet and Avon Canal to avoid confusion with the Grand Western Canal, which was being proposed at the same time.
In 1793 a further survey was conducted by John Rennie, and the route of the canal was altered to take a more southerly course through Great Bedwyn, Devizes, Trowbridge and Newbury. The proposed route was accepted by the Kennet and Avon Canal Company, chaired by Charles Dundas, and the company started to take subscriptions from prospective shareholders. In July 1793 Rennie suggested further alterations to the route, including the construction of a tunnel in the Savernake Forest. On 17 April 1794 the Kennet and Avon Canal Act 1794 (34 Geo. 3. c. 90) received royal assent and construction began. The Newbury to Hungerford section was completed in 1798, and was extended to Great Bedwyn in 1799. The section from Bath to Foxhangers was finished in 1804, and Devizes Locks were completed in 1810.
