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 July 21 to July 28, 2017

Throughout the week of July 24, 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.

From 10:00PM on Friday, July 21st to 7:00PM on Sunday, July 23rd, ramp H4, connecting Highland Avenue Eastbound (toward Newton) to I-95 Northbound (towards Waltham) will be detoured. This closure will allow the ramp to transition to its permanent alignment for tie–in to the Highland Avenue Bridge and the collector-distributor roads. A separate release has been released on the details of this weekend operation.

On Tuesday July 25, traffic will be shifted to the median from Kendrick Street to the southern Limits of work on the southbound mainline.

Between Highland Avenue and Kendrick Street, project team members will be constructing the southbound collector-distributor road from Kendrick Street to Highland Southbound Monday July 24 to Wednesday July 26. Construction of the southbound collector-distributor road tie-in at ramp H5 (Highland Avenue Westbound to I-95 Southbound) will occur Thursday July 27 and Friday July 28. Construction of the northbound collector-distributor road and installation of drainage at the entrance to the K2 ramp (Highland Avenue Eastbound to I-95 Northbound). Forming, reinforcing, and pouring of bridge barrier and the median over the Highland Avenue Bridge will also occur all week.

From Highland Avenue to Central Avenue, work for the week will address installation of retaining wall panels, backfill, wall caps, and formwork and supports for the Western Arch. Additionally, forming, reinforcing, and pouring of the northeast and southeast wingwall will occur.

At Route 9, work will include drilling and installing the drill pad for Cedar Street noise wall posts, installation of precast median barrier, and forming, reinforcing, and pouring of barrier around sign foundations.

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 Northbound to Highland Ave Westbound (H3) and Route 9 Eastbound to I-95 Southbound (W5) 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.
