[edit] Attleboro

A short segment of Route 1A, 1.8 miles in length, in Attleboro runs from U.S. Route 1A at the Rhode Island border through a junction with Interstate 95, before heading north and merging with Route 1. The entire length of this segment is known as Newport Avenue.

[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 former 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 through Revere. It is a limited access highway through Revere, passing Suffolk Downs and the Wonderland Greyhound Park (which is across the street from the outer terminus of the MBTA's Blue Line, before running through the isolated Point of Pines neighborhood) and exiting Revere over the General Edwards Bridge into Lynn. For the first mile and a half in Lynn, it is concurrent with the Lynnway, and is a high-traffic retail area. After the Lynnway portion, the route becomes concurrent with Route 129 for a mile, before crossing into Swampscott. From there it passes into Salem, passing by Salem Common before crossing the Beverly-Salem Bridge into Beverly. It follows two of the main streets of downtown Beverly, before heading north, passing through Wenham and Hamilton (through this section the road is occasionally signed as a US Route) before becoming the main road through the town of Ipswich, crossing the historic Choate Bridge over the Ipswich River. While in Ipswich, much of the route runs concurrently with Route 133 until just over the town line into Rowley. It passes through the main village of Rowley, as well as the central villages of Newbury. In Newburyport, Massachusetts, it merges with Route 1, signed with its parent highway over the Merrimack River and into the town center of Salisbury. It then heads east from the Salisbury town center before turning north and ending in Salisbury Beach at the New Hampshire border. New Hampshire Route 1A continues north from this point.
