I recently attended an East Coast Greenway committee meeting and was inspired to check the status of the route on OSM. The ECG is a bicycle/ped route that runs from Maine to Florida. People use the relation to do route planning via OpenCycleMap and some other tools where it shows up. The route needs period review as little splits occasionally break the connectivity.
I created a wiki page to track the progress of updates, which I last conducted in earnest about a year ago. Any help welcomed!
