The decision to route Interstate 95 through Route 128

In response to the outcome of the 1970 Boston Transportation Planning Review, Massachusetts focused federal highway funding 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 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. Since then, the highway has had three sets of exit numbers: I-93 exits 7–1 from the southern terminus to the I-95 junction in Canton, I-95 exits 26–64 (old exits 12–45) from the I-95 junction in Canton to the I-95 junction in Peabody, and the original Route 128 exits 37–55 (old exits 29–12) 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 (now exit 28) in the renumbering and thus coincidentally retained its number until the switchover with the mileage-based system in 2021. Along with other highways in the commonwealth, exits were renumbered with a mileage-based system in 2021. 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

, Route 128 runs eastward 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

, partially removed circa 1977, was one of the leftover structures from this plan as well as the existing expressway (part of US 1 since 1989). The decision to reroute I-95 onto Route 128 rather than building a new highway inside of Route 128 has contributed to three 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 has been referred to 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 Southeast Expressway, as the only highway coming into Boston from the south, carries more than double its capacity on a daily basis. The highway is prone to some of the worst traffic in the region, as all traffic from south of the city (coming from three different highways) must merge onto this one route. The political decision not to build new highways inside of Route 128 also led to abandonment of plans to extend the US 3 freeway from its current interchange with the Yankee Division Highway in Burlington to a junction with Route 2 in Lexington as originally planned. This decision caused a temporary reroute of US 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.

and interchanges in the 1960s—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 55 (old exit 12, the interchange with Crafts Road), the route runs eastward as a four-lane expressway 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 another intersection at Route 127 (Eastern Avenue) to its terminus in another intersection at Route 127A (East Main Street/Bass Avenue).


History

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

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

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).

in Canton, Milton, Quincy and Braintree, Norfolk County acquired 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. West Street led to Route 37, which ran southeast to Braintree center. This part of Route 37 had been taken over by the state in 1919 (to Braintree center) and 1917 (in Braintree center). 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 1933,1933 General Drafting Boston and vicinity map 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.

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". In 1957, there were 99 companies employing 17,000 workers along Route 128; in 1965, 574; in 1973, 1,212.

. This widening project was completed in 1964, and involved replacement of all of the old overpasses with new ones. In 1967, with the enaction of a policy that limited each road to one route number a decision was made to drop the designation of Route 128 from the Southeast Expressway and to redesignate the orphaned segment from exit 35 (old 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. 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 officially named "America's Technology Highway" 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 the Yankee Division Highway designation. With the designation of the part of the highway as I-95 in 1973, the need to upgrade it to

became apparent. By the 1980s, traffic levels had also increased on the section significantly due to the change. In 1988, this section was finally brought to Interstate standards, and the new interchanges with I-95 were finally completed. In 1991, parts of the roadway had their shoulder converted into travel lanes at peak travel periods. In late 2001, a project to resurface the road in Lexington and Burlington was completed. 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 and guide signs on Route 128/I-95 from Route 9 (exit 36, old exit 20) in Wellesley to Route 4/Route 225 (exit 49, old exit 31) in Lexington and, as part of the Add-A-Lane project discussed above, new signs were put up along a section of the I-95/Route 128 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) had been replaced by the end of 2011. Future projects would replace the signs on I-95 (south of Route 128) between the Rhode Island state line and the interchange with I-93, US 1, and Route 128 in Canton in 2018 and (along I-95/Route 128) between I-93 in Reading and US 1 in Peabody in 2019. New mileage markers were placed every 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/Route 128 from Canton to Peabody. New markers put along Route 128 (north of I-95) 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. During the 1960s reconstruction of Route 128, a provision had been made for a fourth lane within the widely spaced

along the length of Route 128 running from just north of the US 1 interchange in Dedham, Massachusetts, northwestwards to the Route 109 interchange, and this would finally be used for the Add-A-Lane project. The $315 million MassDOT Highway Division project has widened the existing 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 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 35A (old exit 19A) with the ramps to Highland Avenue become exits 35B and 35C (old exits 19B and 19C). 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 27 and 29 (old 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 four 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, Route 3, is also in the process of undergoing a similar "add-a-lane" project for much of its own length. Construction on the sixth and final segment in Needham and Wellesley began in January 2015, and included wider bridges and more auxiliary lanes and a new collector road. Major road construction ended in October 2018, and the project wrapped up with painting and landscaping in the spring of 2019.
