Grantham Canal

The Grantham Canal ran 33 miles (53 km) from Grantham through 18 locks to West Bridgford, where it joined the River Trent. It was built primarily for the transportation of coal to Grantham. It opened in 1797 and its profitability steadily increased until 1841. It was then sold to a railway company, declined, and was finally closed in 1936. It was used as a water supply for agriculture, and so most of it remained in water after closure, although bridges were lowered. Since the 1970s, the Grantham Canal Society have been working to restore parts of it. Two stretches are now navigable to small vessels. A new route will be required where the canal joins the Trent, as road building has severed the original one.

The concept of a canal from the River Trent to Grantham was first raised on 27 August 1791, as a way of supplying the district with cheaper coal. The intent was for the navigation to join the Trent below Nottingham at Radcliffe-on-Trent. As William Jessop was surveying the Nottingham Canal at the time, he was asked to survey the Grantham route as well, and a bill was put before Parliament in 1792. It was defeated, as there was opposition from coal suppliers, who delivered coal by road to Grantham, and from those who thought that the River Witham would be damaged by the project. A revised route was developed, with the junction now at West Bridgford, and an additional 3.6-mile (5.8 km) branch to Bingham. A second bill was put forward and the act of Parliament, the Grantham Canal Act 1793 (33 Geo. 3. c. 94), received royal assent on 30 April 1793. Building work on the canal started in 1793, with Jessop in overall charge, but with James Green and William King as resident engineers: Green, who was from Wollaton, was appointed engineer for the section of canal from the Trent to the Leicestershire border, while King, who was the agent for the Duke of Rutland, was responsible for the rest of the canal, including two reservoirs, one at Denton and the other at Knipton on the River Devon.^[1]

The act authorised an initial £75,000 to be raised to pay for construction, together with an option to raise a further £30,000, of which £20,000 should be raised by shares of £100 each among the initial subscribers, and £10,000 by mortgaging the future income of the canal. However, this amount proved insufficient, and there was also disagreement between the shareholders as to their liability to raise the additional £20,000. As a result, a second act of Parliament was sought. This received royal assent as the Grantham Canal Act 1797 (37 Geo. 3. c. 30) on 3 March 1797, and made clear the obligations of existing shareholders to pay the extra subscription, and also authorised an additional £24,000 to be raised. The second act also removed restrictions in the first act, and allowed the company to set whatever rates it chose for using the canal.^[2]

The eastern section from the Leicestershire border was opened on 1 February 1797, with the rest of the canal later that year. The canal was built with locks 75 by 14 feet (22.9 by 4.3 m), the same size as those on the Nottingham Canal to allow boats to use both. The branch to Bingham authorised by the first act of Parliament was not built. The 18 locks raised the level of the canal by 140 feet (43 m) from the Trent to Grantham. Eleven of them were in the first 4 miles (6.4 km) above the Trent, after which there was a level pound of around 20 miles (32 km) before a flight of seven locks at Woolsthorpe, and a much shorter upper pound to Grantham. At Harlaxton, the canal passed through a deep cutting (effectively crossing the watershed between the River Witham and the River Trent), which was only wide enough for a single boat, but this situation was partially rectified in 1801 when the cutting was widened in two places to allow boats travelling on opposite directions to cross. At Cropwell Bishop and Cropwell Butler, the route passed through gypsum beds, which resulted in problems with leakage.^[3]

A plan to fill in a section of the canal in Nottingham resulted in a number of letters appearing in the local press in 1963, and a student at Kesteven College produced a report on the state of the canal, which was presented to the Grantham Civic Society.^[15] In 1970, the British Waterways Board attempted to obtain an act of Parliament which would have allowed them to cease maintaining the water levels of the canal. The Inland Waterways Association campaigned against the bill, and the clause was amended. The Grantham Canal Society was formed soon afterwards, to promote restoration of the waterway.^[16] In 1974, a National Boat Rally was held at Nottingham, to gain support for the restoration scheme, and to promote the idea of a new link to the Trent, which would pass through old gravel workings.^[17]

Together with British Waterways, the Inland Waterways Association and the Waterway Recovery Group, the society began the work of restoration of the canal to navigation, a process which is still ongoing. A major development was the granting of permission in 1992 to remove an old railway embankment, which blocked the route near the top of the Woolsthorpe flight of locks. The task was completed by a number of Waterway Recovery Group workcamps.^[18] New gates were fitted to the top three locks, and rebuilding of Casthorpe bridge was funded by Lincolnshire County Council,^[19] opening up 4.4 miles (7.1 km) of the canal for navigation. Further down the canal, restoration of a 2.3-mile (3.7 km) section between Hickling Basin and Hose was funded by a derelict land grant of £400,000, received in 1993.^[18] The Grantham Canal Partnership was formed in 1997, as a way to take the project forwards. It consisted of representatives from each of the six local authorities through which the route passes, British Waterways, the Inland Waterways Association, the Grantham Canal Restoration Society and the Grantham Navigation Association, a group which had split off from the Canal Society in 1992. As a result of the co-operation, British Waterways formulated a draft business plan for the canal.^[20]

Following the restoration of the top three locks at Woolsthorpe in the 1990s, a 10-mile (16-km) section from the A1 to Redmile will be completed once the bottom four locks of the flight are restored.^[11] The rebuilding of locks 6 and 7, completed in 2000, brought the number of locks restored to five, and approximately one quarter of the canal has been restored to navigable standard.^[21] Much improvement of the towpath has also taken place, and access to it is possible at most of the bridges.^[11]

A major setback occurred in 2007, when one of the walls of Woolsthorpe Top Lock had to be propped to prevent it collapsing, and British Waterways took the decision to fill it in, as funding was not available to rebuild it. The Inland Waterways Association received a legacy of £100,000 from the estate of Fredrick Woodman, designated for the Grantham Canal, but British Waterways ruled that no work could start until the whole cost of £175,000 had been found. The balance was made up by grants of £40,000 from Lincolnshire County Council and £35,000 from the East Midlands Development Agency. The wall was demolished and rebuilt in three sections, utilizing 290 cubic yards (220 m³) of concrete and 7,500 new bricks.^[19]

The Canal and River Trust applied for a Heritage Lottery Fund (HLF) grant to cover the costs of rebuilding locks 12 to 15 of the Woolsthorpe flight using volunteers. A visit by the Heritage Lottery Fund in November 2014 resulted in a grant of £830,000, to cover reconstruction of locks 14 and 15, which was match funded by money from the Canal and River Trust and from Grantham Canal Society. Work began in August 2015, and was completed by July 2018, with an official opening taking place on 13 September 2019.^[22] The Society were assisted by the Waterway Recovery Group, and because of the HLF funding, the project included training of their own volunteers in the skills needed to build locks. This enabled them to begin restoring lock 13 in 2024, the next in the flight, without the need to involve outside labour. The restoration is expected to take about two years and cost around £250,000.^[23]

Restoration of most of the canal does not present major problems, but challenges are presented by the final sections at both ends. The original route to join the Trent has been severed by the building of the A52 road. A route was identified which followed the course of the Polser Brook, which passes under the A52 to the north of the canal,^[24] but by 2009, three possible solutions were under consideration.^[11] These pose additional problems in finding funding, since they do not count as restoration, and many of the traditional funding sources are not then available. At Grantham, an embankment carrying the A1 road blocks the line of the canal, and the terminal basin has been filled in.^[11] There are plans for a tunnel under the A1 as part of a cycle route to improve access to Grantham, and the basin could be redeveloped in due course.^[25]

There is also a 5-mile (8 km) dry section between Cotgrave and Kinoulton, which has presented problems since construction in the 18th century: gypsum in the soil reacted with the waterproof clay leading to leaking.^[26]

In early 2005, the Grantham Canal Partnership appointed a full-time Grantham Canal restoration manager, Kevin Mann, for an initial 18-month trial period. He would be responsible for planning and managing funding schemes for the restoration, identifying development opportunities and the promotion and interpretation of the canal. The trial proved to be successful, as he was still doing the job in 2009.^[27]

The canal and its banks between Redmile and Harby is designated a biological Site of Special Scientific Interest as Grantham Canal SSSI.^[28]

The Duke of Rutland also constructed a private wagonway or tramway between the wharf at Muston Gorse and Belvoir Castle. It was constructed in 1814–15, and remained operational for 100 years.^[29] It was constructed with fish-belly rail set into stone chairs, some of which, and some wagons, still exist in the castle cellars.^[30] The gauge was 4 ft 4+1⁄2 in (1,333 mm), and the rails were supplied by The Butterley Company. Some are in the collection of the science museum,^[31] and the National Railway Museum where there is the chassis of one of the wagons.^[32]
