The Montgomery Canal (), known colloquially as "The Monty", is a partially restored canal in eastern Powys and northwest Shropshire. The canal runs from the Llangollen Canal at Frankton Junction to Newtown via Llanymynech and Welshpool and crosses the England–Wales border.
The canal was formally named as the Montgomery Canal in the British Waterways Act 1987. However, it was informally known by this name prior to this act. It consists of the Eastern and Western branches of the Montgomeryshire Canal and the Llanymynech Branch of the Ellesmere Canal. The Montgomeryshire Canal ran from Llanymynech to Newtown. It was named after the county of Montgomeryshire that it ran through and was divided into Western and Eastern branches which met at Garthmyl. At Carreghofa Locks near Llanymynech, the Montgomeryshire Canal connected to the Llanymynech Branch of the Ellesmere Canal. The Llanymynech Branch ran from Carreghofa Locks to Frankton Junction where it meets the present-day Llangollen Canal.
The Montgomery Canal does not, and never did, go to the town of Montgomery. The three constituents of the present-day Montgomery Canal became part of the Shropshire Union Canal system: the Ellesmere Canal including the Llanymynech Branch in 1846, the Eastern Branch in 1847 and the Western Branch in 1850.
The canal fell into disuse following a breach in 1936 and was officially abandoned in 1944. At present, only from Frankton Junction to Crickheath Bridge is navigable and connected to the rest of the national Canal & River Trust network. Separately, a section at Llanymynech and a section of the canal around Welshpool are navigable though isolated from the national canal network. Ongoing restoration work continues to connect the navigable sections.
History
The Montgomeryshire Canal was devised with a different purpose from most other canals of the time. Whereas other canals could generate sufficient revenue from cargo carrying to be financially viable, the Montgomeryshire was planned to serve a more rural area which would not offer such opportunities. Instead, the primary purpose of the canal was to transport lime for agricultural purposes which would allow the Upper Severn Valley to become better agricultural land. As a result, the promoters of the canal included local landowners who hoped to achieve a return on their investment through greater crop yields rather than relying upon share dividends.
The original 1792 proposal for the Montgomeryshire Canal was for a route from Llanymynech, where it would join the proposed Llanymynech Branch of the Ellesmere Canal, to Welshpool. By 1793, it had been decided that the canal should continue through to Newtown. The canal was authorised in 1794 by an act of Parliament, the (34 Geo. 3. c. 39), entitled "An act for making a navigable Canal from or near Porthywain Lime Rocks in the parish of Llanyblodwell, in the county of Salop, to or near Newtown, in the county of Montgomery, and also certain collateral Cuts from the said Canal." The company was authorised to raise £72,000 from shares and a further £20,000 if required. John Dadford was appointed Engineer while his brother Thomas Dadford Junior was appointed his assistant. There had been suggestions in 1793 for a connecting canal between Garthmyl and the Leominster Canal at Woofferton. It would have been long but the plan came to nothing.
By February 1796, parts of the canal were completed and the first boat, named the Royal Montgomery, was launched into the canal near Welshpool amidst great celebrations. In July 1797, the connection to the Ellesmere Canal at Llanymynech was opened although the Llanymynech branch was still suffering from problems with leakage. A month later, the canal had reached Garthmyl providing of navigable canal from Llanymynech but stopping short of Newtown. In early 1797 John Dadford had resigned his post in order to pursue a career in America and, at the suggestion of Thomas Dadford, had been replaced by his father Thomas Dadford senior. During construction, there had been problems with both the Berriew Aqueduct and the Vyrnwy Aqueduct where one arch had collapsed. The management committee were unhappy with this and the engineer William Jessop was called in to advise but he explained that such issues were merely teething problems and allayed their fears. To reach Garthmyl, £71,000 had been spent. The canal thus far included 13 locks: four descending between Carraghofa and Burgedin and nine rising from there to Garthmyl. It included a level branch to Guilsfield, some long.
Although conceived as a means to serve agricultural communities, trade on the canal developed steadily. There were a number of quarries in the Llanymynech area which delivered limestone to the canal for transport to kilns at Belan and elsewhere. Grain prices rose from 1800 onwards and there was a large demand for lime as a fertiliser so that the Welsh hill-lands could be enclosed and developed for agriculture. Once the Chirk and Pontcysyllte aqueducts were opened on the Ellesmere branch to Llangollen, there was an easy route for the transport of coal used in the lime kilns to produce fertiliser. Other cargoes included stone for building, roofing slates, timber and bark. At its outset, the Earl of Powis had been one of the principal shareholders in the canal; he and his son, Lord Clive, were both landowners and owners of quarries and mills along the canal. The first dividend of 2.5 per cent was paid in 1805 and thereafter, a dividend was paid in most years while the canal remained independent at rates up to 5.5 per cent. Volumes of limestone carried rose from 14,082 tons in 1806 to 44,592 tons in 1814 while carriage of slack coal rose from 6,757 tons to 11,560 tons over the same period. There was a significant drop in volumes with the end of the Napoleonic Wars but trade had picked up again by 1820.
Western extension A lack of capital and income prevented completion of the canal and Garthmyl remained the terminus for 20 years but by 1812, Newtown was experiencing significant growth and there were calls to extend the route southwards, either as a canal from Garthmyl to Newtown or as a canal to Bryn-derwen and a tramroad beyond that. A meeting of the shareholders held in October 1813 narrowly voted to press on and Josias Jessop was asked to survey the route. His initial estimate was £28,268 although some of the committee later thought that he had forgotten to include the cost of puddling and lining the canal. The company agreed to put a Bill before Parliament to obtain the necessary powers but factions developed within the shareholders with some fearing that they might lose their investment if the canal were completed. Heated meetings were held in September 1814 and January 1815 at which neither side was entirely successful but on 3 February 1815, the company agreed that the new section would effectively be built by a separate company with its own committee and accounts.
The old company would be known as the Eastern Branch with the new company responsible for the Western Branch. Any profits that the Eastern Branch made above 5 per cent would be used to fund the extension and on completion, the two branches would be jointly managed. Surpluses from the Eastern Branch would continue to be transferred to the Western Branch until it was able to pay a 5 per cent dividend at which point the two companies would be formally amalgamated. This was enshrined in the (55 Geo. 3. c. lxxxiii) which authorised the raising of £40,000 in new shares to complete the canal. The new company kept themselves separate failing to notify the Eastern Branch how the work was progressing. Under the supervision of John Williams, the resident engineer, who used Jessop's plans, the new canal was completed in March 1819 although it was not formally declared to be complete until 7 December 1821. It descended through six locks from Newtown and was supplied with water from the River Severn by a water wheel and a backup steam engine. An additional supply came from a weir and feeder at Penarth.
The six locks were each deep with the cut being deep and wide at the bottom. As a result of the Western Branch needing to be profitable to allow the branches to merge, a higher tonnage charge was imposed on the Western Branch. On 23 June 1821 a further act of Parliament, the (1 & 2 Geo. 4. c. cxix), was obtained to alter the line of the Tanat feeder and to make a navigable cut from the Guilsfield Branch. This act stipulated that the consolidation of the Eastern and Western branches would no longer be automatic but would require the consent of the proprietors of each and clarified that the commencement of the Eastern branch was to be taken as the distance of thirty-five yards from the sill of the upper gate of the higher of the two Carreghofa locks. This alteration to the line of the Tanat feeder resulted in it now supplying the pound above the Carreghofa locks whereas it had previously fed only the Eastern Branch as it entered the canal between the locks.
The cost of the Western Branch was £53,390 which was well in excess of the £22,300 which had been raised by issuing new shares. The company had borrowed £6,000 from the Exchequer Bill Loan Commissioners and the rest from various others, the majority coming from William Pugh. Income on the new branch was meagre so that the company could not meet the interest payments on the loans and factions developed. One group was led by Pugh who complained that the engineer Williams had muddled the accounts since the canal had opened and another group thought that Pugh had borrowed money beyond the powers granted by the act of Parliament. They wanted the Exchequer Bill Loan Commissioners to investigate the company's financial position. However both parties agreed that George Buck, who had been the engineer for the Eastern Branch since 1819, should become engineer and clerk and he was appointed to this post in December 1832 with a mandate to investigate the accounts.
Buck presented his findings in November 1833 but the meeting took no action as Pugh was absent. Buck moved on the following month to assist Robert Stephenson on railway projects. Pugh then paid off both the capital and interest of most of the other creditors resulting in the company owing him £38,106 which was split into a mortgage for £25,000 and £13,000 in shares. He then obtained his own act of Parliament, the (4 & 5 Will. 4. c. xviii) to authorise his position and to allow the company to raise their tolls. By June 1835, the Western Branch declared that receipts were sufficient to pay the interest on all mortgages but there is no evidence that any dividends were ever paid on the shares. The two branches remained separate companies throughout their life.
Shropshire Union takeover Major structural repairs to the Vyrnwy aqueduct had been required in 1823 when all of the arches were strengthened by iron bands under the supervision of Buck. Otherwise, the Eastern Branch continued to be relatively prosperous apart from a brief dip during a trade recession between 1840 and 1844. This was partly due to the late arrival of railways in the area. The Western Branch, in contrast, was hampered by the fact that nearly all of the traffic was in one direction towards Newtown with very little goods travelling in the opposite direction.
