History

In 1790s a consortium of coal owners and industrialists sought Parliamentary approval to build canals to link the industrial areas of the N valleys with Newport on the Usk estuary, the canals in turn to link with a system of feeder tramroads. Bill received assent in 1792 and Monmouthshire Canal Navigation company was formed to build two canals; that in the Western Valley, also known as The Crumlin Arm and 11 miles (17.6km) long, was designed to join the Eastern Valley canal just N of Newport, completed c 1797. Engineer Thomas Dadford. Reservoirs to feed canal constructed in mountain valleys to E. In 1865 the Brecknock and Abergavenny and Monmouthshire Canals merged to become the Monmouthshire and Brecon Canal which was later incorporated into the Great Western Railway. Much of the Western Valley canal has been filled in to provide a by-pass road but a section survives stretching from the S side of Cwmcarn, the community boundary with Abercarn, to Darren Road, the community boundary with Risca.
