The East Coast Greenway is the nation's most ambitious long-distance urban trail project.   By connecting existing and planned shared-use trails, a continuous, traffic-free route is being formed, serving self-powered users of all abilities and ages. 3,000 miles long, the Greenway links Calais, Maine at the Canadian border with Key West, Florida. Alternate routes will add another 2,000 miles to the ECG trail system.

The idea of this green city-to-city travel corridor emerged in November 1991. The team of 10 co-founders soon began forming the East Coast Greenway Alliance to transform their vision into reality.

A linear park, the East Coast Greenway will be entirely on public right-of-way, incorporating waterfront esplanades, park paths, abandoned railroad corridors, canal towpaths, and pathways along highway corridors.
