The East Coast Greenway, or ECG, is a project to create a nearly 3,000-mile (4,800 km) urban path linking the major cities of the Atlantic coast of the United States, from Calais, Maine, to Key West, Florida, for non-motorized human transportation. It is similar in length and conception to the 12 routes of the EuroVelo project throughout Europe, and the Trans Canada Trail project in Canada.
Work on ECG began in 1991. As of 2013, 29% of the trail is complete (off-road).
In 1991, a group of cyclists and long-distance trail enthusiasts met in New York City and formed a national non-profit organization, the East Coast Greenway Alliance (ECGA), to plan and promote a greenway linking existing and planned trails into a contiguous "spine route" between Atlantic coast cities.
A planned alternative to the Richmond-Wilmington leg of the journey hews closer to the coast, passing through Virginia Beach in the Tidewater region and continuing on through the Elizabeth City, Greenville, New Bern and Jacksonville in North Carolina before rejoining the main line near the mouth of the Cape Fear River at Wilmington. Other alternate routes are planned for Maine, Massachusetts, and Florida.
