Massachusetts Route 203

The Massachusetts Route 203 is a 5.18 mi (8.3 km) of State Route in Boston, Massachusetts in the United States with gradient from west to east. It begins in the Jamaica Plain neighborhood in Jamaica Pond, and then runs south-east and east across the Arborway and Morton Street and Gallivan Boulevard Parkway to its end at Neponset Circle in Dorchester neighborhood where it connections to the U.S. Highway 1, the I -93, Massachusetts offers Route 3 and the Massachusetts Route 3A.

Maintenance

Before the Massachusetts Department of Transportation ( MassDOT ) was founded in 2009, the Massachusetts Route 203 was wholly owned by the Department of Conservation and Recreation (DCR ). On November 1, 2009, the then Bishop William Casey Highway Overpass in Jamaica Plain, the Morton Street in Mattapan transferred and Gallivan Boulevard in Dorchester to the MassDOT, while the Arborway remained under the control of the DCR.

History

The Massachusetts Route 203 was formed in the early 1970s as part of an extensive renaming or renumbering of streets surrounding the city of Boston. Most of the route was previously part of Massachusetts Route 3, which ran south with U.S. Highway 1 along the Jamaicaway and branched off from this to the east along the present route. Route 3 turned to the Granite Avenue to the south to meet in Milton on the Southeast Expressway, while the non- branching path as Massachusetts Route 3A was continued.

As part of the new numbering Route 3 were performed on the Southeast Expressway to the city center, the route 3A shortened to end at its present and former routings of Route 3 and 3A reassembled to Route 203. At the same time the end of U.S. Highway 1 has been moved so that it no longer connects to a numbered State Route today.
