State officials stress that these three projects are still active construction sites, and that public access is officially prohibited for the sake of public safety and getting the job done. Though these trails have been paved, the Northern Strand and Cochituate Rail Trail projects each include several bridges and overpasses that aren't yet passable.
Cochituate Rail Trail, Natick
Natick's new trail extends an existing 1.2 mile trail in Framingham south into Natick's town center by way of a scenic former railroad right-of-way that hugs the shore of Lake Cochituate (pictured at the top of this post).
The project will also install two bridges over two dangerous roadways that currently divide Natick's neighborhoods. One bridge will span Route 9, a four-lane divided highway, and make it possible for people to walk or bike between Natick Center and the Natick Mall.
A second bridge will carry the trail over Commonwealth Road at the Framingham city line:
This new trail will run from the eastern shore of Fresh Pond in Cambridge to the existing Watertown Greenway, giving Watertown residents and workers an easy off-street bike ride to the Red Line station at Alewife, and to the Minuteman and Mystic River bike path networks north of there.
Northern Strand Trail, in Lynn, Saugus, and Revere
Bike to the Sea sent out these photos from the North Shore's hotly anticipated Northern Strand Trail extension project, which will extend the existing paved pathway in Malden all the way to Lynn, in its most recent newsletter. Construction has been paused for the winter and three bridges over the marshes near the Saugus-Lynn border have yet to be installed, but much of the project's paving is complete.
