Heybridge is adjacent to Maldon, near the River Blackwater. It is often overshadowed by its historic neighbour, and one could mistakenly think it to be the same town, as the two have merged with one another over the years.
The final stage of the Chelmer and Blackwater Navigation Canal runs from Beeleigh through Heybridge and terminates at Heybridge Basin. This stage of the canal required much planning and work at its inception, as a constant running water supply was needed to the two mills nearby, in Langford and Heybridge. This was achieved through the diversion of the river Blackwater and extensive works around the Beeleigh locks. The Chelmer and Blackwater Navigation Canal was originally used to transport coal & wood to the inland town of Chelmsford, as the road route via Danbury crests the highest hill in Essex. The canal was used for this purpose until the late 70's. Today it is mainly used for pleasure boats and fishing.
