From Brecon to Newport
The Monmouthshire Canal is mostly under restoration, with only the 2.2 miles (3.5 km) from Pontymoile Junction to Cwmbran Tunnel fully navigable. The canals are isolated from the main connected network of waterways in England and Wales.
The Monmouthshire Canal and the Brecon and Abergavenny Canal were proposed at the same time and joined at Pontymoile, although they were operated separately until the companies merged in 1865. They were built to transport coal, lime, iron, iron ore and agricultural products.
