Rhode Island border to Attleboro A short segment of Route 1A, 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.
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. Prior to its realignment along
I-95 and
I-93, Route 1 continued north along the Providence Highway towards Boston at the junction of Route 1A and that road.
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) and
Sumner Tunnel (inbound/southbound), becoming the East Boston Expressway past
Logan Airport. The East Boston Expressway was the first freeway built in the city. 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 as Paradise Road. At
Vinnin Square, it passes into
Salem as Loring Avenue, passing by
Salem State University. The route turns left onto Lafayette Street and is concurrent with Route 114. At the intersection with Derby Street, notable for the large fire station, the route turns right. At the next stop sign, the route turns left onto Hawthorne Boulevard passing Salem Common and the
Salem Witch Museum before turning left onto Winter Street. At the end of Winter Street, the route turns right onto Bridge Street crossing the
Veterans Memorial 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. ==History==
