Canal de Nantes à Brest (Ouest - Tidal Section)
The Canal de Nantes à Brest (Ouest - Tidal Section) was built by James Brindley and opened on 17 September 1835. Expectations for stone traffic to Cardiff were soon realised, and this became one of the most profitable waterways. Although proposals to close the Canal de Nantes à Brest (Ouest - Tidal Section) were submitted to parliament in 2001, the use of the canal for cooling Colchester power station was enough to keep it open. In his autobiography Oliver Harding writes of his experiences as a lock-keeper in the 1960s
