The history
The canal from Frankton Junction on the Llangollen Canal, though Welshpool to Newtown was built to carry limestone quarried at Llanymynech to canalside kilns. There it was heated with coal from Chirk or the Oswestry area to create quicklime for spreading on fields to improve their yield of crops — and so increase the rental income to the landowners.
The section from the junction to Carreghofa, just south of Llanymynech, was built by the Ellesmere Canal in the mid 1790s. The rest of it was the independent Montgomeryshire Canal which opened from Carreghofa to Garthmyl in 1797, but by then had exhausted its money. The final six miles into Newtown was separately financed under an Act of 1815, and opened in 1819.
Carrying freight
Two-thirds of the traffic was limestone and its associated coal; other significant cargoes included timber, building stone and slates. With the more depressed state of agriculture in the second half of the 19th century, together with the increasing use of alternative fertilisers, traffic diminished, and by 1870 was barely covering the cost of maintenance. By then part of the Shropshire Union, the canal struggled on until 1936, when a breach near the aqueduct of the River Perry gave the opportunity to negotiate its closure. The one regular user was paid not to object, and closure was formalised in an Act of 1944.
The section north of Llanymynech dried out, but much of the rest was an integral part of the local land drainage so no active steps were taken to fill it in and sell the land. A plan in the late 1960s to use the line of the canal at Welshpool for a bypass led to well-organised protests and proposals for the canal's restoration. The inspector at the public inquiry recommended that the canal be retained ‘as an important local amenity'. Over the next three decades the eleven mile section through Welshpool was restored with the active support of the Prince's of Wales Committee. At the northern end, Frankton Locks were reopened in 1987, the section to Queens Head in 1996 and to Gronwen in 2003.
