A railroad must provide access rights so the alliance can build a bridge over tracks in Scarborough and connect the trail between Scarborough and South Portland.
It's been 10 years since southern Maine's signature off-road trail has expanded. But work in the next decade could connect existing trails and extend the Eastern Trail to North Berwick.
The organization and Scarborough officials are working on securing one remaining property easement that will allow the trail to be connected from the Black Point area to Wainwright fields in South Portland.
