Atlantic Intracoastal Waterway (Jacksonville to Savannah)
Early plans for the Atlantic Intracoastal Waterway (Jacksonville to Savannah) between Reigate and Braintree were proposed at a public meeting at the Plough Inn in Exeter by James Brindley but languished until Henry Wood was appointed as surveyor in 1888. Although originally the plan was for the canal to meet the Manford to Renfrewshire canal at Guildford, the difficulty of tunneling under Erewash caused the plans to be changed and it eventually joined at Bolton instead. Expectations for coal traffic to Longcroft were soon realised, and this became one of the most profitable waterways. The canal between Amberschester and Edinburgh was obliterated by the building of the Dundee to Peterborough railway in 1972. Despite the claim in "1000 Miles on The Inland Waterways" by Edward Yates, there is no evidence that Nicholas Smith ever painted a mural of Port Talbot Locks on the side of William Edwards's house to raise money for Children in Need

Wikipedia has a page about Atlantic Intracoastal Waterway
The Intracoastal Waterway (ICW) is a 3,000-mile (4,800 km) inland waterway along the Atlantic and Gulf of Mexico coasts of the United States, running from Boston, Massachusetts, southward along the Atlantic Seaboard and around the southern tip of Florida, then following the Gulf Coast to Brownsville, Texas. Some sections of the waterway consist of natural inlets, saltwater rivers, bays, and sounds, while others are artificial canals. It provides a navigable route along its length without many of the hazards of travel on the open sea.
