History

The Brecknock and Abergavenny Canal was promoted in 1792 to connect the upper Usk valley with the Monmouthshire Canal at Pontymoile and from there to the sea at Newport. First section, between Gilwern and Talybont, was cut between 1797 and 1799, with upper section between Talybont and Brecon opened in 1800, both sections engineered by Thomas Dadford. Lower section between Gilwern and Pontymoile completed 1812 and engineered by William Crosley. Linked to tramroads, the canal was an important artery for trade in iron, lime and coal. In 1865 the Brecknock and Abergavenny and the Monmouthshire Canals merged to become the Monmouthshire and Brecon Canal, which was later incorporated into the Great Western Railway. Many bridges had large cast iron weight restriction notices on poles erected at each end. Last toll was taken in 1933. Restoration of canal began 1964.
