It Will Be A Long Time A Coming

The East Coast Greenway. I have never heard of it before. A nice article about the project.

Aiming to connect cities and towns of the East Coast with a continuous, traffic-free path, the East Coast Greenway spans 3,000 miles from Maine to Florida. With nearly one-fifth of the ECG on traffic-free paths, and the rest mapped out on interim roads, people and communities all along the east coast are already enjoying the Greenway's benefits.
Frequently likened to an urban Appalachian Trail, the East Coast Greenway is the nation's first long-distance urban trail system; a city-to-city transportation corridor for cyclists, hikers, and other non-motorized users. By connecting existing and planned trails, a continuous, safe, green route 3,000 miles long is being formed linking Calais, Maine at the Canadian border with Key West, Florida. It incorporates waterfront esplanades, park paths, abandoned railroad corridors, canal towpaths, and highway corridors, and in many areas it temporarily follows streets and roads to link these completed trail sections together.

Already, 21 percent of this route is along off-road trail and the aim is for it to be entirely off-road and traffic-free. The East Coast Greenway Alliance will continue to work toward that end until it is 100 percent off-road. Obviously, that will take many years, much as the Appalachian Trail has taken decades to be moved off-road. Many people are surprised to learn that in the beginning, the Appalachian Trail was largely on roads too.

Good luck!
