Route 203 is a 5.5-mile (8.9 km) state-numbered route in Boston, Massachusetts, United States, running from old U.S. Route 1 in Jamaica Plain east to Interstate 93/U.S. Route 1/Route 3 and Route 3A at Neponset. It runs along the Arborway, Morton Street and Gallivan Boulevard, all parkways formerly part of the Metropolitan District Commission system of parks and roads.
Prior to the creation of the Massachusetts Department of Transportation (MassDOT) in 2009, the route was owned and maintained by the Department of Conservation and Recreation (DCR, previously the Metropolitan District Commission). On November 1, 2009, the Msgr. William Casey Highway overpass in Jamaica Plain, Morton Street in Mattapan and Gallivan Boulevard in Dorchester were transferred to MassDOT, while the Arborway continued under DCR.
