The Massachusetts Department of Transportation is developing a system of bicycle routes throughout the state, called the Bay State Greenway. Eventually there will be 500 miles of shared-use paths, 200 miles of which already exist.
Priority projects include the following:
- The Wayside Trail , also know as the Mass Central Rail Trail.
- The Mohawk Trail Bikeway would connect the city and Williamstown parallel to the Hoosic River and Route 2.
- The Southampton Greenway will connect to the Manhan Bike Trail in Easthampton.
- The Quequechan River Bike Path: 7 miles in Fall River
- The Mattapoisett Rail Trail, 26 miles southeast of Mattapoisett
The Neponset River Greenway, connecting Boston’s Hyde Park, Mattapan and Dorchester to the Town of Milton.
- The Hyannis Transportation Center Connector: Barnstable to Hyannis
- The Salisbury Bike Trail connection to the Border to Boston Trail
- The Wayside Trail , a section of the Mass Central Rail Trail
- The Bruce Freeman Trail, a 25 mile proposed rail trail through the communities of Lowell, Chelmsford, Westford, Carlisle,Acton, Concord, Sudbury, and Framingham
- Reformatory Branch Trail 4 miles through three natural areas: Elm Brook Conservation Area, Mary Putnam Webber Wildlife Preserve, and Great Meadows National Wildlife Refuge.
- Somerville Comunity Bike Path connecting Somerville to the Minuteman Bike Trail .
The brochure Bicycling in Massachusetts gives details of how the state intends to spur implementation of the Bay State Greenway. MassDOT has identified the 100 miles of highest priority shared-use path projects as the BSG 100 to hasten connections to urban centers, extend existing paths, and maximize the transportation network.
