Oxford Canal

The Oxford Canal was constructed in several stages over a period of more than twenty years.

In 1769 an Act of Parliament authorising the Oxford Canal was passed, having been promoted in Parliament by Sir Roger Newdigate MP, who chaired the canal company. The intention was to link the industrial English Midlands to London via the River Thames. Construction began shortly after near Coventry. The principal motivation for the canal was the transport of coal from the Midlands to Oxford and London.[4][5]

Surveying of the route and initial construction were originally supervised by the celebrated engineer James Brindley, assisted by Samuel Simcock who was also Brindley's brother-in-law. Brindley died in 1772, when the canal had only reached Brinklow, and Simcock took over. By 1774 the canal had reached Napton, but the company was already running out of money.[4][5]

In 1775, a second Act was passed allowing the company to raise more funds. Construction soon started again and by 1778 the canal had reached Banbury. Financial problems meant that work on the final stretch from Banbury to Oxford did not begin until 1786, and when it did, James Barnes was appointed as the engineer. As funds were limited, the Banbury-Oxford stretch was built more cheaply, and to lower standards than the rest of the canal, and many cost saving measures were used whenever possible: Wooden lift or swing bridges were built, instead of more expensive fixed brick bridges. Deep locks were used wherever possible, with single gates at both end instead of double gates. A stretch of the River Cherwell at Shipton-on-Cherwell was incorporated into the canal. This reduced construction costs, but the behaviour of the river makes the canal more difficult to use.[4][6]

The Oxford Canal reached the outskirts of Oxford in 1789, when a coal wharf was opened at Heyfield Hutt, now the site of Hayfield Road. The final section into central Oxford was ceremonially opened on 1 January 1790.[7]

The Duke's Cut, a short link from the Oxford Canal to the River Thames, just north of Oxford, was built in 1789 by the Duke of Marlborough.[4]

The River Swift (a tributary of the River Avon) connected to the original route of the Oxford Canal near Cosford and was used as a water feeder to the canal. In 1785 there was a proposal to make the river navigable from the Oxford Canal at Cosford to the town of Lutterworth in Leicestershire. This proposal however never came to fruition. The River Swift, however is still an important feeder to the northern Oxford Canal, via the now unnavigable Brownsover Arm; a part of the canal which was bypassed when the canal was straightened.[5]

For the next 15 years the Oxford Canal became one of the most important and profitable transport links in Britain, with most commercial traffic between London and the Midlands using the route. Its principal traffic was coal from Warwickshire. It also carried stone, agricultural products and other goods.

A much more direct route between London and the Midlands, the Grand Junction Canal, was completed in 1805, connecting Braunston to London in much less distance. Much of the London-bound traffic switched to this faster route, as it avoided the passage of the River Thames which still had many flash locks. This greatly reduced Oxford Canal traffic south of Napton. However, the short section between Braunston and Napton became the link between the Warwick and Napton Canal and the Grand Junction Canal, making it part of the busy direct route between Birmingham and London. Despite these developments, the Oxford Canal remained highly profitable during this period; from 1824 to 1826, the company paid dividends of up to 55% to its shareholders.[5]

The Grand Junction and Oxford canal companies were bitter rivals. When Parliament considered the Act of Parliament for the building of the Grand Junction, the Oxford Canal successfully petitioned to make the Grand Junction pay "bar tolls" to the Oxford Canal to compensate for the loss of traffic south of Napton.

Traffic from Birmingham had to use five miles (8 km) of the Oxford Canal to get from Braunston to join the Grand Junction at Napton. The Oxford Canal exploited this by charging high tolls for Grand Junction traffic on this short section.

The abandoned tunnel at Newbold on the old route of the canal

The Oxford Canal was originally built as a contour canal, meaning that it twisted around hills to minimise vertical deviations from a level contour. This meant however that the canal followed a very winding and circuitous route: Although the distance between Coventry and Napton was only 16 miles (26 km) as the crow flies, the distance by the original route of the canal was 43 miles (69 km). This mattered little when the Oxford Canal had no competition, however, with increased canal competition, and one eye on the developing railway network, the company decided to straighten the route.[4]

In 1827 Marc Isambard Brunel (father of Isambard Kingdom Brunel)[8] re-surveyed the northern section of the canal between Braunston and Hawkesbury Junction to straighten it out and reduce navigation time. The following year another survey was carried out by Charles Vignoles. The work to straighten the canal was carried out between 1831 and 1834, the majority of the work being in the Rugby area, and this reduced the distance by 14+3⁄4 miles (23.7 km). The original tunnel at Newbold-on-Avon was abandoned when the canal was straightened, and replaced by a new one on a different alignment. The south portal of the old tunnel can still be seen next to the churchyard.[5] The old line of the canal was either abandoned, or remained in use as arms serving various village wharves. The section south of Napton was never straightened.[4]

The straightening of the canal coincided with the beginning of the railway age, and the opening of the London and Birmingham Railway in 1838, signalled the end of the dominance of the canals. However, despite the railway competition, the total tonnages of cargo carried on the canal did not decline immediately, and in fact continued to rise for some time, however, the company was forced to slash its tolls in order to remain competitive, and this put an end to the large profits which had previously been made, although ironically the railways provided a new source of income to the canal, who paid them to provide water for their locomotives at Rugby. Traffic on the canal remained such that the three locks at Hillmorton, the first on the canal after the stop lock at Hawkesbury Junction, became severely congested. The solution to the congestion was to duplicate or twin the existing locks at Hillmorton, creating three pairs of two parallel narrow locks, which allowed twice the traffic to pass the lock at any time. The work to double the locks was completed in August 1840. In 1842, nearly 21,000 boats passed through the locks.[5][4]

In 1833 a section of the new line of canal in Barby Fields near Dunchurch was used as a test site for a new wrought iron boat, Swallow, built by Graham and Houston. Drawn by two horses, the boat completed a distance of 1.5 mile in 7 minutes 35 seconds, a speed of almost 12 miles per hour.[9]

Traffic on the Oxford Canal held up reasonably well in the face of railway competition compared to many other navigations, but did see a gradual decline; in 1838, 520,000 tons were carried, which declined to 482,000 tons in 1868. However, income declined much more sharply due to the company slashing its tolls; takings which had gone from £18,478 in 1791/3, and then risen to a maximum of £90,446 in 1827/29, then fell to £26,312 in 1855. Nevertheless, the company was still profitable, and was able to pay dividends.[5]

The northern section of the Oxford Canal between Coventry, Braunston and Napton remained an important trunk route, and remained extremely busy with freight traffic until the 1960s. The staple traffic was coal from the Warwickshire and Leicestershire coalfields to London via the Grand Union Canal. However, the southern section from Napton to Oxford became something of a backwater, and carried mostly local traffic.

In 1934, the Braunston-Napton stretch of the canal was taken over by the recently formed Grand Union Canal company, and widened as part of that company's London to Birmingham main-line.[4]

In a bid to raise funds to overcome an arrears of maintenance, in 1936, the Oxford Canal Company decided to sell off their terminal basin at Oxford. In 1937 Baron Nuffield (Later Viscount Nuffield) bought the canal basin at Oxford for £133,373[10] (equivalent to £9,155,800 in 2021).[11] In 1951 he filled it in and built Nuffield College on part of the former coal wharf. Coal traffic was relocated to a canal wharf in Juxon Street, in Jericho, Oxford. The goods wharf and the remainder of the coal wharf are now under a public car park that Nuffield College lets to Oxford City Council. For this reason, the canal today ends abruptly in central Oxford.[4]

Many Oxford Canal boatmen and women favoured horse traction long after those on other canals had changed their narrowboats to diesel power. In the 1930s, only around one in thirty of the boats trading on the canal's southern section was mechanically powered.[4] One narrowboat carrying coal on the Oxford Canal was drawn by a mule until 1959 and was the last horse-drawn freight narrowboat in Great Britain. This boat, Friendship, is preserved at the National Waterways Museum, Ellesmere Port.[12]

The Oxford Canal remained independent until it was nationalised in 1948 and became part of the Docks and Inland Waterways Executive, later the British Waterways Board. The Oxford Canal remained profitable until the mid-1950s, paying a dividend right up until nationalisation. As with most of Britain's narrow canal system, the Oxford Canal suffered from a rapid decline in freight traffic after the Second World War. By the mid-1950s very few narrowboats traded south of Napton and the southern section was at one point being threatened with closure, although the northern section (Napton to Coventry) remained well-used by commercial traffic until the 1960s.

During the 1960s pleasure boating began to grow in popularity and replace the old trading boats, After a fact-finding cruise on the canal, Barbara Castle (Minister for Transport) rejected a proposal for closure.[13] The canal was designated as a cruiseway under the Transport Act 1968, which defined at as being a waterway to be maintained for leisure use.[4]

The canal is now thriving. In the summer it is one of the most crowded canals on the network.
