Project Status

Barletta Heavy Division, Inc. is the prime contractor. Construction began in January 2015 and is expected to be completed in Spring 2019. MassDOT established an interim milestone requiring a portion of the new Kendrick Street Interchange to be open to traffic in Fall 2016.

The project has been split into five major stages to minimize impacts to the traveling public. Stage 1 (January 2015 to October 2015) includes the following:

  • Widening the northern half of the Kendrick Street Bridge while maintaining the existing three lanes on the structure.
  • Building Kendrick Street ramp bridge to I-95 NB.
  • Commencing construction of the new Highland Street Bridge while maintaining traffic on the existing spans.
  • Initial construction at the interchange of I-95 and Route 9.
  • Demolition of the railroad bridge over I-95.

View the Project Overview page for more detailed information including the new Interchange Ramp Configurations.

Current Construction Activities: Period of September 23rd to September 30th

There will be a public information meeting related to upcoming traffic shifts and other work for this project on Wednesday, October 19th, 6:30pm to 8:30pm at the War Memorial Auditorium at Newton City Hall, located at 1000 Commonwealth Avenue in Newton. All are encouraged to attend. Please share this information with your friends, family, coworkers and anyone else you think you benefit from the information.

Throughout the week of September 26th, 2016, Barletta Heavy Division (BHD), MassDOT's contractor for the Route 128 Add-a-Lane Bridge V project, will continue construction operations. Work will be performed project-wide during the standard working hours of 7:00AM to 3:00PM.

At Ramp K1 (Kendrick Street Westbound to I-95 Northbound), bridge fence will be installed. At Ramp K2 (collector/distributor from Kendrick Street Eastbound under Highland Avenue to the ramp from Highland Westbound to I-95 Northbound) curb slope and utility castings will be installed. At Kendrick Street, lane markings and signage will continue to be adjusted as necessary.

At Highland Avenue, excavating and preparing the Highland Avenue Bridge for demolition will occur throughout the week. Relocating traffic on Ramp H5 (collector/distributor road from Highland Eastbound to Kendrick Street), as well as striping of Highland Avenue and Ramps H5 and H6 (I-95 Southbound to Highland Westbound) will occur on Monday September 26th. Dense and fine grading of Ramp H5 will occur Tuesday through Friday, September 26th through 28th. At the Highland Avenue median, installation of timber piles along the Southbound side, excavation of Southbound piles for LTP, and building of the embankment along the Northbound platform area will occur throughout the week.

There will also be a weekend operation at Highland Avenue beginning at 8PM on Friday, September 23rd and running to 5AM on Monday, September 26th. As part of shifting all traffic to the new Highland Avenue Bridge the ramp from Highland Avenue to I-95 Northbound will be detoured. All traffic will move to the new Highland Avenue Bridge on the night of Saturday, September 24th.

During the ramp closure, traffic seeking to access I-95 Northbound will be detoured as follows:

  • Traffic headed to I-95 Northbound will be detoured as follows:
    • Proceed down Highland Avenue
    • Turn left at Oak Street
    • Turn left at Chestnut Street
    • Go under the Route 9 Overpass and immediately turn left for the on-ramp for Route 9 West
    • Immediately take the on-ramp for I-95 North (toward Peabody)
  • Alternatively, traffic can proceed as follows:
    • Turn left on Webster (at the Needham Fire Station, before the Bridge)
    • Turn left on Central Avenue
    • Take the second right onto Cedar Street
    • Turn right on Worcester Street to merge onto Route 9 Eastbound
    • Use the right lane to take the on-ramp for I-95 North toward Peabody

At Central Avenue, the Central Avenue Bridge will be graded, back-filled, and the base course paved. At the Route 9/I-95 interchange, operations will focus on guard rail installation. On the I-95 mainline, the base course will be paved south of Kendrick Street.

At Central Avenue and the Railroad Bridge, the Central Avenue Bridge will be waterproofed Monday and Tuesday, September 26th and 27th. Wednesday through Friday, September 28th through 30th, back-fill and grading will occur.

BHD will be closing lanes during off-peak hours to continue construction of all bridges. Lane closures are permitted and are necessary to create a safe work zone; drivers are asked to be aware of possible lane closures for their own safety and that of the project team. Please also note that all work is contingent upon the weather.
