Monmouthshire Canal

The Monmouthshire Canal ran for 9 miles from its junction with the Brecon & Abergavenny Canal at Pontymoile to the Usk Estuary at Newport.  The Crumlin Arm left the main line at Malpas Junction and extended 10.75 miles to Crumlin.  Only the northernmost portion of the canal (above Cwmbran Tunnel) is open for Navigation, but the remainder is under restoration.

Restoration Potential

The unrestored portion of the Monmouthshire Canal and its Crumlin Arm is mostly urban and heavily locked, but would provide a coastal access route as well as increasing the length of  the combined Monmouthshire, Brecon & Abergavenny Canals to make them an even more viable waterway holiday destination.

Waterway underfunding

Hundreds of miles of waterways – along with their unique heritage and habitats – are currently starved of funding and rely on constant lobbying by us to safeguard their future.

Sustainable Boating

We want boating on canals and rivers to be more sustainable and – even though the current overall contribution to UK carbon emissions is very small – we want to help reduce emissions on the waterways.

Waterways Heritage at Risk

Britain’s canals and rivers are a unique, living heritage. But that heritage is at risk – from urban development, lack of protection, loss of skills and knowledge and climate change.

You can help Save Waterways Heritage.

Waterway restoration

Restoring the UK’s blue infrastructure – our inherited network of navigable canals and rivers – is good for people and places.
