The East Coast Greenway will stretch from Calais, Maine, to Key West, Florida, a 2,900-mile distance. The project will provide non-motorized users a unique way to travel up and down the East Coast through 25 cities and 16 states. Walkers, cyclists, runners and other active-transportation users will be able to travel on a continuous, firm and paved greenway with a route specifically designed to give travelers a traffic-free experience, East Coast Greenway Alliance, the non-profit organization behind the project.
