Acceler-8 I-90 Bridge Replacements Project starts Dec. 2

The Massachusetts Department of Transportation (MassDOT) is upgrading eight bridges on the Massachusetts Turnpike (I-90). The bridges are between Exit 11A (I-495) and Exit 12 (Route 9) on I-90 in the towns of Westborough and Southborough. The bridges, built as part of the original Turnpike, need to be replaced to continue carrying traffic safely and efficiently.

Preliminary work to prepare for this major construction project will begin on Wednesday, December 2, 2020. The public should expect to see the contractor and its subcontractors on-site primarily during the hours of 7:00 AM and 3:30 PM, Monday through Friday. Occasional overnight lane closures will occur on I-90.

The project will replace bridges on I-90 east and westbound over Flanders Road in Westborough and Parkerville Road, Cordaville Road, and Woodland Road in Southborough. The replacement of the eight bridges will take place over eight weekends in summer 2021.

The preliminary work will include the following and take place through early January 2021.

On local roads:

  • A site walk to identify invasive plant species at each of the bridges for removal prior to the start of major construction;
  • Setting up sound monitoring equipment to measure pre-construction sound levels to develop a noise management plan; and
  • Relocating a fiber optic cable underground in the Flanders Road southbound shoulder.

On I-90:

  • Off-peak lane closures to collect survey data

Public information meetings will be scheduled throughout the project. Please be sure to sign up for the email list at the website link below to receive meeting notices and project updates.

Fourth Street off-ramp closures begin Sept. 21

Tobin Bridge & Chelsea Curves Rehabilitation Project Update

There will be daily closures of the Fourth Street off-ramp beginning Monday, Sept. 21 and ending Friday, Sept. 24. The closures will take place during the day from 7 a.m. to 3 p.m.

Fourth Street Off-Ramp Detour

Motorists with destinations in Chelsea are advised to get off at the Beacon Street ramp, which is the first available exit after crossing the Tobin Bridge into Chelsea. A police detail will be present at the bottom of the Beacon Street off-ramp to ensure that traffic on the ramp does not back up onto the mainline of Route 1. Any motorist who misses Beacon Street can also exit Route 1 northbound at Webster Avenue Chelsea/Everett.

Build Parcel 12 – Construction at I-90, Mass Ave. & Boylston St.

A large construction project over the Massachusetts Turnpike (I-90) just east of Fenway Park begins this month. It will effect traffic on I-90, Massachusetts Avenue, Boylston Street and the surrounding area.

From the Build Parcel 12 website

Building over the Massachusetts Turnpike — two new buildings connected by a landscaped public plaza, enhancing the heart of one of Boston’s most walkable districts.

Starting in August 2020, construction begins over the Mass Pike (I-90) and Worcester Line Commuter Rail tracks, while improving the highway on-ramp and Mass Ave to bring safer pedestrian, bicycle, and transit connections.

Featuring storefront retail, a hotel, and world-class office space, Parcel 12 will knit together the Back Bay and Fenway neighborhoods, connect the South End and the City of Cambridge, and vastly improve the street-level experience along Massachusetts Avenue between Boylston and Newbury Streets.

Because this project is building on air rights over the highway, it requires closing one highway lane in each direction in the area of construction as steel and concrete is erected to form a deck over the Turnpike. Throughout construction, the construction team will work together with the City of Boston and MassDOT so you know when and how work and lane closures will happen, share tips on how you can adjust your commute if you want to avoid driving, and answer your questions about the construction process.

An online public meeting was held on Aug. 11 with a presentation of the project highlights. We encourage you to review the presentation to be better informed about the project that will run into 2022.


Tobin Bridge & Chelsea local traffic advisories through Feb. 22

This is a brief overview of construction operations and traffic impacts for the Tobin Bridge/Chelsea Curves Rehabilitation Project. MassDOT will provide additional notices as needed for high-impact work, temporary ramp and street closures, and changes to traffic configurations beyond those described below.

Route 1 Traffic Impacts

Local Street Closures

These closures are necessary to create a safe workzone for necessary bridge work.

  • Underneath Route 1: Crews will install SafeSpan walkways, replace and paint steel; power wash and paint columns and support beams; excavate, drill, and grout around support columns; erect steel; place new concrete columns; and install ground anchors.

Travel Tips

Drivers should take care to pay attention to all signage and move carefully through the work zone. Police details, lane markings, temporary barriers, traffic cones, signage, and other tools will be used to control traffic and create safe work zones.

The contractors are coordinating with local event organizers and police to provide awareness and manage traffic during events. For your awareness, the following events are scheduled at TD Garden during this look-ahead period:

Advisory: Sumner Tunnel Toll Plaza Reconstruction

On Monday, June 17, 2019, MassDOT will activate the permanent swing gates and electronic signage controlling the swing lane at the Sumner Tunnel Portal where Route 1A enters the tunnel.

The system will automate and enhance the process currently in-place for the deployment of the swing lane to alert motorists to the status of the swing gates as they approach the tunnel.

Images of the changes have been provided by MassDOT within a PDF document.

MassDOT: Current projects with lane impacts

MassDOT has updated their Current Construction Projects with Lane Impacts, as well as the presentation with an overview of 2019 construction projects. The documents were updated May 16.
