canal was authorised in 1794 by an Act of Parliament 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John Dadford had resigned his post in order to pursue a career in America and, at the suggestion of Thomas Dadford, had been replaced by his father Thomas Dadford senior.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 also 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
