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.

Current Construction Activities: Period of September 15 to Septembe22, 2017

Throughout the week of September 18, 2017, Barletta Heavy Division (BHD), MassDOT’s contractor for the I-95/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. All project work is currently underway within the Town of Needham, except at the I-95/Route 9 Interchange, which is located in Wellesley.

Over the weekend beginning September 15, Ramp W7, connecting I-95 Southbound to Route 9 Westbound) will be closed in order to facilitate full depth reconstruction. Milling of Highland Avenue Eastbound and Westbound will be done on Thursday September 21. Project team members will be performing full depth reconstruction of the northbound high speed lane over the weekend of September 23 and 24.

Between Highland Avenue and Kendrick Street, drainage will be installed along the northbound and southbound shoulders south of Kendrick Street Monday through Thursday. Additionally, edging along the southbound collector-distributor road and precast barrier along the northbound collector distributor road will be installed throughout the week.

From Highland Avenue to Central Avenue, work throughout the week will address installation of retaining wall cap, barrier, and backfill for the Western Arch, as well as forming, reinforcing, and pouring of the eastern wingwalls.

At Route 9, work will include installing mechanically stabilized earth abutment walls Monday through Saturday (September 18 to 23), as well as forming reinforcing and pouring of pier footing Monday through Wednesday and pier columns Thursday through Saturday.

BHD will be closing lanes during off-peak hours to continue construction of all bridges. It is anticipated that nightly ramp closures of I-95 Southbound to Highland Ave Eastbound (H6) and I-95 Southbound to Route 9 Westbound (W7) will occur to facilitate upcoming weekend work. Lane closures 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 - especially related to paving - is contingent upon the weather.
