Route 128, also known as the Yankee Division Highway, is a state highway in the U.S. state of Massachusetts maintained by the Highway Division of the Massachusetts Department of Transportation (MassDOT). Spanning 57 miles (92 km), it is one of two beltways (the other being Interstate 495) around Boston, and is known as the "inner" beltway, especially around areas where it is 15 miles (25 km) or less outside of Boston. The route's current southern terminus is at the junction of I-95 and I-93 in Canton, and it follows I-95 clockwise around Boston for 37.5 miles (60.4 km) before I-95 leaves the highway, and Route 128 continues on its own in a northeasterly direction towards Cape Ann. The northern terminus lies in Rockport a few hundred feet from the Atlantic Ocean. All but the northernmost 3 miles are divided freeway, with the remainder being a surface road.
Originally designated in 1927 along a series of surface streets, Route 128 provided a circumferential route around the city of Boston. The original route extended from the seaport of Gloucester, on the North Shore, to the beach resort community of Hull on the South Shore. Construction of the present circumferential highway began in Gloucester the early 1950's and progressed southward, in part on new alignments and in part by the improvement of older roads, and came to completion with the final link into the Southeast Expressway (Massachusetts Route 3/John Fitzgerald Expressway/Pilgrim Highway) at a three-way flying junction known as the Braintree Split. With the completion of the final segment of the Yankee Division Highway in Braintree in 1960, the segment of Route 128 through Braintree, Weymouth and Hingham was rerouted to run concurrently with Route 3 on the Southeast Expressway/Pilgrim Highway between the Braintree Split (Route 3 Exit 19, Route 128 exit 67) and Exit 14, then along Pond Street in Norwell to Queen Anne's Corner on the Hingham-Norwell line, retaining its original route from Queen Anne's corner to its terminus in Hull. Subsequent upgrades on the northern segment in the 1960s completed a full freeway from Braintree in the south to Gloucester in the north.
Over time, the southern terminus was truncated twice.
- Circa 1965, a policy of limiting each road to one route number led to a decision to drop the designation of Route 128 from the Southeast Expressway and to redesignate the orphaned segment from Exit 14 of the Southeast Expressway to the terminus in Hull as Route 228 - but with its designated directions reversed to reflect the actual geographical direction of the new route. This shifted the southern terminus of Route 128 to the Braintree Split.
- Circa 1997, the same policy led to removal of the designation of Route 128 from the segment of the Yankee Division Highway between the Braintree Split and the junction with the southern segment of I-95 in Canton, which had been designated as I-93. The plan also would have removed the designation of Route 128 from the segment between the junction with the southern segment of I-95 in Canton and the junction with the northern segment of I-95 in Peabody, but this was rescinded because it would have orphaned a railroad (Amtrak/MBTA) station named "Route 128" that's adjacent to the highway in Canton. However, that segment retains the "Yankee Division Highway" name.
However, twenty years later, the entire segment of the highway as "Route 128" even in traffic reports on radio and television in local parlance, often causing considerable confusion for uninitiated visitors to the area.
In local culture, "Route 128" is generally recognized as the demarcation between the more urban inner suburbs and the less densely developed suburbs surrounding the city of Boston. It also approximately delimits the region served by the rapid transit and trolley system operated by the Massachusetts Bay Transportation Authority (MBTA), and is used to reference the high-technology industry that developed from the 1960s to the 1980s in the suburban areas along the highway.
Route 128 begins in Norfolk County in the south, at the interchange with I-93, I-95, and US 1 in Canton. Until the 1990s, its southern terminus was located at the junction of I-93, US 1, and Route 3 (the Braintree Split) in Braintree. At this present-day terminus, 128 becomes concurrent with I-95, and follows the sequential exit numbering scheme used by I-95 as it enters Massachusetts from Pawtucket, Rhode Island. It also begins a wrong-way concurrency with US 1; as 128 and I-95 are signed traveling north, US 1 is signed traveling south, and vice versa. US 1 splits onto its own roadbed at exit 15 in Dedham.
In the 1980's, the administration of Governor Michael Dukakis made a policy decision to focus on public mass transportation rather than building new highways through Boston and the inner suburbs ("inside of Route 128"), cancelling plans for completion of a Northeast Expressway and construction of a Southwest Expressway to carry I-95 through downtown Boston. This policy cascaded into designation of the segment of the Yankee Division Highway between the existing I-95 junction in Canton and the new I-95 junction in Peabody as I-95 rather than building a new highway to complete the connection, coupled with a decision to extend I-93 southward along the Central Artery and John Fitzgerald Expressway (Massachusetts Route 3) and onto the southern end of the Yankee Division Highway to the I-95 junction in Canton. After completion of the I-95/Route 128 interchange in Peabody in 1988, the State Highway Department changed the numbers of all exits south of the newly completed junction to those of the respective interstate highway designations. Thus, the highway now has three sets of exit numbers -- I-93 exits 7 through 1 from the southern terminus to the I-95 junction in Canton, I-95 exits 12 through 45 from the I-95 junction in Canton to the I-95 junction in Peabody, and the original Route 128 exits 29 through 12 from the I-95 junction in Peabody to the northern terminus. The interchange with I-93 in Woburn, which was Route 128 Exit 37 before the renumbering, became I-93 Exit 37 in the renumbering and thus coincidentally retained its number.
As a result of this political decision, about two thirds of Route 128 runs in tandem with I-95 from Canton north to Peabody, and after I-95 splits off and continues north from Peabody toward New Hampshire, northward on its own right of way from Peabody to Gloucester. The I-95 and I-93 signage were added in the mid-1970s when plans to construct I-95 through Boston, directly connecting the two I-95/Route 128 interchanges, were cancelled leaving a gap filled using Route 128. An unused cloverleaf in Canton, now partially removed, was one of the leftover structures from this plan as well as the existing Northeast Expressway (now part of US 1.)
The decision to reroute I-95 onto Route 128 rather than building a new highway inside of Route 128 has contributed to two significant problems.
- At the junction in Canton, I-95 northbound uses the original cloverleaf, which is fairly tight, to transition from the southern segment to the Yankee Division Highway. More than a few unsuspecting truckers have entered the cloverleaf at full highway speed and thus managed to flip over their rigs. As a result, the cloverleaf is now known as "Dead Man's Curve" to locals.
- The I-95 overhead traffic also has become a major contributor to congestion on the segment of the highway known as I-95.
The area along the western part of Route 128 is home to a number of high-technology firms and corporations. This part of Route 128 was dubbed "America's Technology Highway", and signs marking it that way were put in place beginning in October 1982. Two years later, those blue signs were changed to read "America's Technology Region" after complaints from veterans groups that noted the highway already had a name: the Yankee Division Highway, a name bestowed in 1941 in honor of the U.S. Army unit first formed in Boston in 1917.
The political decision not to build new highways inside of Route 128 also led to abandonment of plans to extend the limited access divided highway designated as U. S. Route 3 from its current termination at the Yankee Division Highway in Burlington to a junction with Route 2 in Lexington as originally planned. This decision caused a temporary reroute of U. S. Route 3 onto the Yankee Division Highway, but in the opposite direction, to connect with its original route, one interchange to the north of the current junction, to become permanent.
The segment of the highway that still carries the sole designation as Route 128, which is now four lanes of limited access divided highway for most of its length, was not originally built as a limited access divided highway. Many junctions in this segment were constructed as signaled intersections at grade in the 1950's and subsequently reconstructed with grade separation and interchanges in the 1960's - often with local streets that happened to be in convenient locations doubling as ramps for access to the highway. However, four junctions nearest the northern end in the town of Gloucester were not improved. Proceeding in the direction signed as northward beyond Exit 12 (the interchange with Crafts Road), the highway runs eastward through two rotaries, named Grant Circle (intersection with Washington Street) and Blackburn Circle (intersection with Dory Road going northward and Schoolhouse Road going southward) and a signaled intersection at Route 127 (Eastern Avenue) to its terminus in another signaled intersection at Route 127A (East Main Street/Bass Avenue). Additionally, the segments from Blackburn Circle to Route 127 (four lanes) and from Route 127 to Route 127A (two lanes), a distance of 1.2 miles, still have no median divider.
A metropolitan planning organization for the Boston area studied the Route 128/I-95 Corridor from approximately 2005–2010. The study focused on the heavily congested section from I-90 (Newton) to US 3 (Burlington), and was completed in November 2010. As of 2010, the highway carried over 200,000 vehicles per day. Some possible improvements to Route 128 include HOV Lanes, reconstruction of shoulders, ramp metering, bus on shoulder, and fiber optic traffic system improvements. More studies will need to be completed before projects will begin.
Surface roads and south Circumferential Highway
As designated in 1927, the original Route 128, called the "Circumferential Highway," followed existing roadways from Gloucester to Hull through Boston's suburbs. The first (northernmost) segment of the present controlled-access highway, which is still just four lanes wide, opened in 1951. Construction progressed southward. The final (southernmost) segment, originally built as the present eight-lane highway that spliced into the John Fitzgerald Expressway (then Route 3 for its entire length, and popularly also known as the Southeast Expressway) at a wye junction now known as the Braintree Split in Braintree. This segment, which opened in 1960, replaced a two-lane undivided road to complete the first circumferential highway around any major city.
Upon completion of the final segment of the Yankee Division Highway, the agency then known as the Massachusetts Highway Department (subsequently reorganized the Highway Division of the Massachusetts Department of Transportation) assigned the concurrent designation of Route 128 to the segment of the Southeast Expressway (Route 3) from Exit 14 to the Braintree Split (Exit 19), linking to the segment of the original Route 128 from the intersection with Route 53 at Queen Anne's Corner at the Hingham-Norwell line to the southern terminus in Hull. That action removed the designation as Route 128 from Blue Hill River Road in Randolph and Braintree, which is now closed to traffic, and West Street, Franklin Street, segments of Washington Street and Plain Street, and Grove Street in Braintree, a segment of Columbian Street, Park Avenue, and a segment of Ralph Talbot Street in Weymouth, and Derby Street and a segment of Whiting Street (Route 53) in Hingham, all of which remain in service for local traffic. However, fate was not so kind to the rest of the original route. Although some segments of remain in service as local parallel streets, other segments became part of the present right of way, but with connections severed at both ends, and some segments were severed where they cross the present right of way and even closed if no longer used by local traffic. Thus, it is no longer feasible to drive the original route between Braintree and Gloucester.
In 1965, the Massachusetts Highway Department truncated Route 128 at the Braintree Split and redesignated the non-freeway section of Route 128 from Route 3 through Hingham and Hull as Route 228, with its direction reversed to reflect the actual geographical direction of that segment of the route. This action ended the concurrent route designation on the John Fitzgerald Expressway.
In the wake of a political decision not to complete the Northeast Expressway and to construct a Southwest Expressway to connect I-95 through Boston as originally planned, the United States Department of Transportation and the Massachusetts Highway Department redesignated the segment of the Yankee Division Highway between the junction with the completed segment of I-95 from Peabody to the New Hampshire border and the junction with the completed segment of I-95 from Canton to the Rhode Island border as I-95 to complete that highway. Concurrently, these agencies extended I-93 from its original terminus in Boston southward on the John Fitzgerald Expressway to the Braintree Split, then westward on the southern segment of the Yankee Division Highway to the junction with the completed southern segment of I-95 from Canton. At that time, the Massachusetts Highway Department officially truncated Route 128 at its intersection with I-95 in Peabody, began removal of Route 128 signage, and assigned I-93 and I-95 exit numbers to the interchanges on both affected segments of the Yankee Division Highway. The Massachusetts Highway Department subsequently restored the designation of Route 128 and reinstalled signage on the segment of the Yankee Division Highway designated as I-95, partly in response to public protest and partly due to the fact that an Amtrak and MBTA commuter rail station adjacent to the highway at the University Avenue interchange in Canton bears the name Route 128 (RTE on the railroad timetables and in the Amtrak reservation system). The station is located at the first interchange north of what's now the junction of I-93 and I-95 in Canton.
Despite no longer officially carrying the designation, the section of the Yankee Division Highway between Braintree and Canton is popularly called Route 128 within Massachusetts. However, signage for Route 128 has gradually disappeared from the segment designated as I-95 as the Massachusetts Department of Transportation has replaced signage along that segment of the road and on the intersecting roads.
At its current southern terminus, Route 128 begins running concurrently with I-95 (same direction) and US 1 (opposite direction). While its concurrency with US 1 ends in Dedham, its concurrency with I-95 continues as it intersects with expressways including I-90 (the Massachusetts Turnpike) in Weston; US 20 in Waltham; Route 2 in Lexington; US 3 in Burlington (with which it runs concurrently within the town); and I-93 and US 1 again in Reading and Lynnfield, respectively. 128 and I-95 split in Peabody; as I-95 continues north towards New Hampshire, 128 travels east towards its northern terminus at an interchange with Route 127A in Gloucester.

The first section of the new Circumferential Highway, in no way the freeway that it is now, was the piece from Route 9 in Wellesley around the south side of Boston to Route 3 (now Route 53) in Hingham. Parts of this were built as new roads, but most of it was along existing roads that were improved to handle the traffic. In 1931, the Massachusetts Department of Public Works acquired a right-of-way from Route 138 in Canton through Westwood, Dedham and Needham to Route 9 in Wellesley. This was mostly 80 feet (24 m) wide, only shrinking to 70 feet (21 m) in Needham, in the area of Great Plain Avenue and the Needham Line. Much of this was along new alignment, but about half — mostly in Needham — was along existing roads:
- Royall Street from west of Route 138 to east of Green Street (Canton)
- Green Lodge Street from Royall Street (now cut by Route 128) to Route 128 Station (Canton and Westwood)
- Greendale Avenue from Lyons Street and Common Street just south of the Charles River to Hunting Avenue (Dedham and Needham)
- Fremont Street north from Highland Avenue (Needham)
- Reservoir Street from Central Avenue to Route 9 (Needham and Wellesley)
From Route 138 in Canton east through the Blue Hills Reservation in Canton, Milton, Quincy and Braintree, Norfolk County acquired a right-of-way in 1927 and built the Blue Hill River Road. This tied into West Street in northwest Braintree, which itself had been taken over by the county in 1923.
The rest of the new highway, from Route 37 east to Route 3 (now Route 53), through Braintree, Weymouth and Hingham, was taken over by the state in 1929. This was all along existing roads, except possibly the part of Park Avenue west of Route 18 in Weymouth.
By 1933, the whole Circumferential Highway had been completed, and, except for the piece from Route 9 in Wellesley south to Highland Avenue in Needham, was designated as Route 128. Former Route 128 along Highland Avenue into Needham center was left unnumbered (as was the Circumferential Highway north of Highland Avenue), but the rest of former Route 128, from Needham center east to Quincy, became part of Route 135. Thus the full route of the Circumferential Highway, as it existed by 1933, is now the following roads:
|Hingham||Derby Street (realigned during construction of Massachusetts Route 3, with two segments of original alignment becoming Old
|Weymouth||Ralph Talbot Street, Park Avenue, Columbian Street|
|Braintree||Columbian Street, Grove Street, Washington Street (Route 37), Franklin Street (Route 37), West Street,|

|Milton||Blue Hill River Road, Hillside Street|
|Canton||Blue Hill River Road, Royall Street, Green Lodge Street (cut by the Route 128/Interstate 95 interchange)|
|Westwood||Blue Hill Drive (cut by Route 128 Station, and later upgraded on the spot as northbound Route 128)|
|Dedham and Westwood||upgraded on the spot as northbound Route 128 (under U.S. Route 1) and then mostly in the median|
|Needham||Greendale Avenue, Hunting Road, southbound Route 128 under Highland Avenue, Reservoir Street|
|Wellesley||inside the present Route 9 interchange|
At the same time as Route 128 was extended along the new Circumferential Highway, it was extended further into Hull. This alignment, not part of the Circumferential Highway, ran southeast on Route 3 (now Route 53) (Whiting Street) to the border of Hingham and Norwell, where it turned north on present Route 228 (Main Street) through Hingham and into Hull. The exact route through Hingham was Main Street, Short Street, Leavitt Street, East Street, and Hull Street. The end of the numbered route was at the south end of Nantasket Beach, where Nantasket Avenue curves northwest to follow the shore of Massachusetts Bay.
"America's Technology Highway"
In 1955, Business Week ran an article titled "New England Highway Upsets Old Way of Life" and referred to Route 128 as "the Magic Semicircle". By 1958, it needed to be widened from four to six lanes, and business growth continued, often driven by technology out of Harvard University and MIT. In 1957, there were 99 companies employing 17,000 workers along 128; in 1965, 574; in 1973, 1,212. In the 1980s, the area was often compared to California's Silicon valley, and the positive effects of this growth on the Massachusetts economy were dubbed the "Massachusetts Miracle".
Major companies with significant locations in the broader Route 128 area prior to 2000 included:
- Apollo Computer
- Digital Equipment Corporation
- Prime Computer
- Wang Laboratories
- Analog Devices
- BBN Technologies
- Honeywell Information Systems
- Thermo Electron and Fisher Scientific, later merged as Thermo Fisher Scientific
- EMC Corporation
- PTC, Inc.
Future and improvements
The $315 million MassDOT Highway Division project has widened the existing 14.3-mile (23.0 km) six-lane section of highway to eight lanes from north of Route 9 in Wellesley to Route 24 in Randolph. The project consists of adding a lane on the inside of each carriageway, complete with a 10-foot inside shoulder. The existing 1950s bridges, 22 in total, also were replaced. The project also included construction of a new two-lane ramp from Route 128 to I-95 in Canton and installation of a new interchange at Kendrick Street in Needham, designated as Exit 19A with the ramps to Highland Avenue become Exits 19B and 19C.
During the initial construction of Route 128, a provision had already been made for a fourth lane within the widely spaced median along the 1.5-mile (2.5 km) length of Route 128 running from just north of the U.S. Route 1 interchange in Dedham, Massachusetts, north-westwards to the Route 109 interchange, and this will finally be used for the Add-A-Lane project.
Construction on phase 1 was officially completed in October 2009. Construction of phase 2 of the project began in summer 2006. This phase of the project consisted of the replacement of the Route 1 and Route 1A bridges over Route 128 in Dedham along with the road widening between Exits 13 and 15 (US 1). Construction of four sound barriers between the US 1 and I-95 interchanges were also included. This phase was completed in the Spring of 2011.
Construction on phase 3, begun in April 2009, widened I-93/US 1 to 4 lanes in each direction from Route 24 to the I-95 interchange. Phase 4 of the Project, which began in March 2011, is replacing seven bridges and widens Route 128 (I-95) to four lanes in each direction from Route 109 to south of Highland Avenue in Needham. The southeastern freeway (Pilgrims Highway) that extends from Braintree to Cape Cod, MA Route 3, is also in the process of undergoing a similar "add-a-lane" project for much of its own 42 mile length.
Sign upgrade projects on Route 128
Over the last fifteen or so years, the state has funded a number of highway sign resigning projects on Route 128 that are replacing the 25-year-old signs with new exit, regulatory and route signs. Starting in 1998 and continuing through 2002, signs were replaced through a $1.1 million project between Reading and Lynnfield. Progress continued in 2005 and 2006 during a $2.2 million project which replaced the signs on from Peabody to Gloucester, and continued with a $1.4 million project in 2008 and 2009 that replaced signs in Peabody and the remaining ones in Lynnfield. A $2.9 million federal stimulus project helped replace exit and highway signs in 2010 and 2011 along Route 128 (I-95) from US-3 in Lexington to I-93 in Reading.
A project begun in the Fall of 2012 and completed in the Fall of 2015, replaced exit & guide signs on Route 128 from Route 9 (Exit 20) in Wellesley to Routes 4/225 (Exit 31) in Lexington and, as part of the Add-A-Lane project discussed above, new signs were put up along section of the project completed in 2015 from Great Plain Avenue in Needham to Route 109 in Dedham. New signage was put up between I-95 and US 1 in 2010 and most of the signage between I-95 and Route 24 (on I-93/US 1) has been replaced by the end of 2011. Future projects will replace the signs between the Rhode Island Border and I-93 in Canton in 2018 and between I-93 in Reading and US 1 in Peabody in 2019. New mileage markers were placed every 2/10 of a mile along the highway in 2010 (except for the area covered by the widening project) for I-93 between Braintree and Canton and I-95 from Canton to Peabody. New markers put along Route 128 from Peabody to Gloucester reflect the state highway's total mileage from Canton, indicating MassDOT's change of heart in decommissioning the route where it shares the road with I-95. The previous mile markers (reflected in the exit list below) had mile 0 in Peabody.
Exit numbers along the I-93 portion of the Yankee Division Highway, indicated by an asterisk in the table below because that segment of the highway is no longer officially part of Route 128, are in accordance with Interstate 93 exit numbering scheme in Massachusetts. Exit numbers along the I-95 portion of Route 128 are in accordance to the I-95 exit numbering scheme in Massachusetts . The stretch north of I-95, as well as the rest of the length before I-95 exit numbering was applied, has decreasing exit numbers traveling northbound, contrary to almost all highways in the US with numbered exits. Route 128 currently has 18 numbered interchanges, starting at 29 (southbound) and continuing downwards to 9 (former Exit 27, an at-grade intersection, was removed, and the last two exits are at-grade intersections). This may be changed over the next few years if all freeway interchanges in Massachusetts are converted to mileage-based numbers under a project that was scheduled to start in January 2016, in order to comply with Federal regulations mandating mileage-based exit numbers on interstate highways, but that, for now, has been indefinitely postponed. The new numbers would abide by standard numbering rules and increase from 37 in Peabody to 54 in Gloucester with the traffic circles and at-grade intersections no longer receiving numbers.
