The Bruce Freeman Trail is a proposed rail trail through the communities of Lowell, Chelmsford, Westford, Carlisle, Acton, Concord, Sudbury, and Framingham in Massachusetts — following the 25-mile route of the old New Haven Railroad Framingham & Lowell line.
Phase 1 (6.8 miles in Lowell, Chelmsford, and Westford) is now open.
Phase 2 in Westford, Carlisle, Acton, Concord, and Sudbury (13.1 miles) and Phase 3 in Sudbury and Framingham (4.6 miles) are proposed extensions.
The Bruce Freeman Trail is open to non-motorized uses such as cycling, jogging, walking, and skiing. Other uses such as rollerblading and equestrian use may also be possible depending on the design.
