Newton Corner Long-Term Planning Study
Working Group Meeting #4 – Discussion Materials
Dear Newton Corner Long-Term Planning Study Working Group,
In advance of the fourth study Working Group meeting on Tuesday, March 31st, MassDOT has posted draft study alternatives on the study website for discussion. These concept-level alternatives are preliminary and intended to illustrate intent rather than detailed design.
The draft alternatives were developed based on feedback throughout the study, including at the third Working Group meeting and the second public meeting. Tuesday’s meeting will walk through these alternatives and present them for feedback prior to alternatives analysis.

Newton Corner Long-Term Planning Study Working Group Meeting #4 Virtual via Zoom: Tuesday, March 31, 2026 4:00 PM – 5:30 PM The Massachusetts Department of Transportation (MassDOT) is announcing the fourth Working Group meeting of the Newton Corner Long-Term Planning Study virtually via Zoom on Tuesday, March 31, 2026 from 4:00 p.m. to 5:30 p.m. You will receive an email from Zoom with information to join the webinar as a panelist. The Newton Corner I-90 Exit 127 (formerly Exit 17) Interchange is a major local and regional connecting point in Greater Boston’s transportation network. The interchange is known for frequent, severe congestion, and is designated a high crash location. MassDOT’s Office of Transportation Planning is carrying out this long-term planning study to develop and evaluate future travel conditions and alternatives for the interchange and its environs. At this meeting, the study team will review feedback from the second Public Information Meeting, present draft alternatives, and discuss the evaluation criteria for alternatives analysis. This will include a discussion with members of the Working Group. The meeting materials will be available after the meeting on the study website. While this is a Working Group meeting and will be conducted as such, per open meeting law the meeting is also open to the public. For more information, please visit the study’s website: https://www.mass.gov/newton-corner-long-term-planning-study. These meetings are accessible to people with disabilities and those with limited English proficiency. Accessibility accommodations and language services will be provided free of charge, upon request, as available. Such services include documents in alternate formats, translated materials, assistive listening devices, and interpreters (including American Sign Language). For accommodation or language assistance, please contact MassDOT's Chief Diversity and Civil Rights Officer by phone (857-368-8580), fax (857-368-0602), TTD/TTY (857-368-0603) or by email at MASSDOT.C...@dot.state.ma.us. |

West Newton is already strained in very real, everyday ways. Traffic is difficult, parking is limited, and nearby residential streets are already carrying more volume and higher speeds than they should.
I’m looking out at Waltham Street as I write this (5:55pm), and it already feels like a through-road. Cars are moving fast (faster than they used to). The City recently added flashing crosswalk lights because of that. Consider the turn restrictions at Washington and Waltham Streets because people regularly ignore them. So we’re not starting from a controlled or well-behaved system, we’re starting from one that’s already under pressure.
I understand the argument that the proposed ramps are not right at Waltham or Chestnut, or Cherry or Elm. But traffic changes don’t stay where they’re built. Once you introduce a new way on and off the Pike, people adjust. Routes change. Apps pick it up. And that’s when nearby streets start functioning differently, not because they were redesigned, but because they become useful as connectors.
The proposed new eastbound off ramp still funnels into Washington and Perkins, and that system is already stressed. At certain times of day, especially when coming from Route 16 into West Newton Square, Washington Street is essentially a line of idling cars.
This feels like a fundamental change, not a small adjustment. It's not something that could easily be reversed either.
A few questions I’d want answered:

To put numbers to Anne's concern about traffic changes to nearby routes as a result of the Washington Street Pilot, see the conclusion of the Fall 2025 study (https://www.newtonma.gov/home/showpublisheddocument/135647/639052999107970000) on page 28:Project Success Metric: Average daily traffic on potential diversion routes has not increased by more than 20%.Status as of Fall 2025: Count programs indicate no substantial increase on potential diversion routes.
More narrative detail is found on page 12.

The ridiculous “road diet” has put more traffic pressure on many parallel streets including Watertown Street, Austin Street and even Commonwealth Avenue. Lowell Avenue runs along the east side of our house and the traffic has increased on Lowell Avenue too.
The road diet must be stopped asap. Forget the 3 year experiment -it has already proven that it is a failure!Traffic is going to be much worse after all those developments are completed along Craft and Washington Streets, too.Best,Anne

i agree with the concerns expressed here by Anne and others. "Full access" it seems to me will primarily benefit commuters traveling through Newton - people who for the most part neither reside nor work here. It will burden residents of West Newton. And while Washington Street would seem to be the natural route for people commuting further east who don't want to get off the Pike at Newton Corner, I suspect that many of the same people who lack the patience for Newton Corner will also not be too happy with the one-lane Washington Street Slalom, and over time discover our local roads like Watertown Street, straighter and with fewer lights.
As for traffic studies, I'll just note that the relationship between traffic volumes and delays can be highly nonlinear. In other words, a 10% increase in traffic volume at 3 in the morning probably wouldn't make much of a difference, but the same percentage during rush hour can make a big difference. (Such phenomena are seen in many other places, like communication networks.) And let's keep in mind that there are about 350 new apartment units under construction just along one small part of Washington Street, and more in the pipeline.

Hello West Newton residents,There is another meeting coming up Tuesday of MassDOT's Newton Corner Long-Term Planning Study Working Group. These meetings are public and on Zoom and you can register here:https://www.mass.gov/event/newton-corner-long-term-planning-study-working-group-meeting-4-03-31-2026In addition to reviewing alternatives for reconfiguring the Newton Corner "circle of death" and surrounding traffic pattern, the Working Group is also still considering changing the West Newton Mass Pike interchange to "full access" (adding westbound on-ramp and eastbound off-ramp). The purpose would be to relieve some of the traffic burden on Newton Corner. This is an enlargement from the meeting materials for the Tuesday meeting:The West Newton redesign could be combined with any of Newton Corner alternatives.Unlike the conceptual drawing from previous Working Group and public meetings, this version appears to show the new ramps being built on property MassDOT already owns, as opposed to running the eastbound exit ramp down what is now Simms Court (where the Burke & Blackington funeral home and two houses are), and perhaps taking a further strip of land along the stretch behind Curve Street and St. Bernard's where so much displacement happened in the 1960s when the Mass Pike was built. But it would, as pictured above, merge the eastbound exit ramp traffic with traffic coming over the bridge.There would presumably be impacts on West Newton traffic in the vicinity which could be both negative (more volume and complexity at the signalized intersection at Washington & Perkins St) and positive (an easier way for West Newton and other northside residents to get on the Mass Pike westbound, or off eastbound). So it's worth paying attention to.Regards,Julia MalakieWard 3 CouncilorNewton Corner Long-Term Planning Study
