[edit] Attleboro
A short segment of Route 1A, just over a mile in length, in Attleboro runs from the Rhode Island border through a junction with Interstate 95 and then merges with US 1.
[edit] North Attleborough to Dedham
This segment of Route 1A extends roughly north from North Attleborough to Dedham, passing through the towns of Plainville, Wrentham, Norfolk, Walpole, Norwood and Westwood on the way.
[edit] Boston to Salisbury
This segment of Route 1A extends from Boston, Massachusetts to Salisbury, Massachusetts.
The highway starts from US 1 (which is on the Central Artery with I-93 and Route 3) at the Government Center/Logan Airport interchange. It passes through the Callahan Tunnel (outbound/northbound, no toll) and Sumner Tunnel (inbound/southbound, toll), becoming the East Boston Expressway past Logan Airport. Immediately beyond Logan Airport, Interstate 90 ends at Route 1A.
The road continues as a divided highway, first as the William F. McClellan Highway. Through Revere, Massachusetts, it is known as Lee Burbank Highway, then as North Shore Road (which runs through the isolated Point of Pines neighborhood) until exiting Revere over the General Edwards Bridge. Much of the highway running through Lynn, Massachusetts is known as the Lynnway. After the Lynnway portion, the route follows mainly undivided local streets for the rest of its length. In Newburyport, Massachusetts, it merges with US Highway 1, signed with its parent highway over the Merrimack River and into the town center of Salisbury. It then ends in Salisbury Beach at the New Hampshire border. New Hampshire Route 1A continues north from this point.
