Southern Artery

From Wikipedia, the free encyclopedia

Southern Artery is a street in Quincy, Massachusetts. For much of its length it is a major arterial street which is used by thousands of Boston area commuters daily. Massachusetts Route 3A enters Quincy from the south at Weymouth Fore River onto Washington Street. Northbound on 3A, as Washington Street intersects Southern Artery, Route 3A turns north toward Dorchester and Interstate 93 along Southern Artery. In this section, Southern Artery is a heavily commercialized four lane undivided strip.

After crossing Coddington Street, Southern Artery and Route 3A continue to Hancock Street, a stretch that in 2001 was renamed the Merrymount Parkway starting at the intersection with Furnace Brook Parkway.

For most southbound travelers reversing this trip, the trip along Southern Artery ends at the intersection with Washington Street where Route 3A heads to Weymouth. Southern Artery in fact extends from this intersection as a two lane street south to Quincy Avenue as the initial stretch of Route 53 through a quieter residential section of Quincy Point.

Its name is derived from the Central Artery, the main north-south highway leading into and through Boston.
