Construction of the Upper Falls Greenway is scheduled to begin in mid October and should take roughly four weeks. Iron Horse Preervation will bring in heavy equipment, remove the track and ties, re-grade the path and then lay down a rolled stone dust surface which will be good for both walking and bicycles.Another recent development is that the private property owner that owns the spur line that runs out to Needham Street has agreed to allow Iron Horse to pull up those rails. It's not 100% clear yet whether that will also be finished as a stone dust trail as part of the initial construction but its a very promising development for eventually connecting the Greenway to Needham St ... and maybe eventually to Christina. The next step is to file for Conservation Commission approval since the spur runs alongside a stream. That's currently in progress.
