Imagine one continuous greenway from the Neponset River to Franklin Park and up Columbia Road to Castle Island. Or from the Mystic River through Sullivan Square and Charlestown to downtown Boston.

This is the future. A 200 mile network of tree-lined, shared-use paths linked together so you don’t have to stop and start. When completed, this system will connect every neighborhood to open space, transit and jobs and thereby increase mobility, promote active recreation, improve climate change resiliency and enhance our city’s competitiveness in the global economy.  

The Emerald Network is an initiative of LivableStreets Alliance 


Featured Greenway - Greenough Greenway, Watertown-Cambridge


Greenough Greenway is a mile-long linear park located on the Charles River between the Eliot Bridge and the Arsenal Street Bridge in Watertown.

Constructed in 1965, Greenough Boulevard was primarily characterized by wide car lanes dominating the river's shore and encouraging speeding. The Greenough Greenway project reclaimed a mile of waterfront parkland from the overbuilt highway and connected one of the best five kilometer path loops in Greater Boston. Numerous residents from the adjacent neighborhoods can now be found enjoying the pathways and new views of the river along the Greenough Greenway on any given day.
