South Coast Rail Construction Activity

Round the Clock Construction Begins on Elements of South Coast Rail Phase 1

MassDOT has begun Early Action construction projects on South Coast Rail to prepare for Phase 1 main line rail construction contracts. The first visible active construction projects are drainage culvert replacement, a railroad grade crossing update and constructing wetlands as mitigation along the right-of-way. Additional work to replace 4 railroad bridges will begin soon. Construction can bring temporary inconvenience, but this phase is expected to move quickly. MassDOT provides regular updates on this website or you can sign-up for the SCR email updates

Work on the Culvert Replacement Project  and in the vicinity of the Tarklin Hill Road Grade Crossing is anticipated to be completed by January 2020.

Phase 1 Construction Update

Location of work:

  • Culvert replacements: BK-4 culvert location in Berkley on the New Bedford Main Line between the Cotley Street and Padelford Street grade crossings (see Early Action Culverts map below under Additional Resources)
  • Grade crossing improvements: Tarkiln Hill Road Grade Crossing in New Bedford

Date/time of work:

  • Culvert replacements: From 7:00 AM through midnight on Thursday, August 15, and from 6:00 AM on Friday, August 16, through midnight on Monday night, August 19 (24 hours a day)
  • Tarkiln Hill Road Grade Crossing: Weekdays between 7:00 AM and 5:00 PM

Additional dates and times will be announced.

Work zone access:

  • Culvert replacements: Primary construction access will be via rail from the Myricks Street grade crossing in Berkley, the Malbone Street grade crossing in Lakeville, and the contractor’s laydown area near the Chace Road grade crossing in Freetown. Materials and equipment will also be staged at these locations. Equipment is expected to utilize these grade crossings and also the grade crossings at Cotley Street and Padelford Street in Berkley throughout the construction period. Employee parking will primarily be located at the Chace Road laydown area and at the rear of the Galleria Mall. All work will be performed on the railroad corridor.

Notes:

  • Culvert replacements: This work will be disruptive to local residents. Crews will be using various pieces of heavy equipment and trucks along the railroad right-of-way throughout the construction period. While the project will seek to minimize construction-related impacts to communities, noise will be generated and work lights will be used along the right-of-way.
  • Tarklin Hill Road Grade Crossing: Vehicular and pedestrian access will be maintained through all roadway work zones and access to local businesses will not be impacted.

Background: Early Action Culvert Construction and Tarkiln Hill Road Grade Crossing

A culvert is an open structure that allows water to pass beneath the railroad tracks. Culverts serve an important purpose as cross-drains for maintaining flow in drainage ditches or stream crossings along the railroad. From Middleborough to New Bedford and Fall River, MassDOT’s Contractor will replace a total of 46 culverts with new precast structures, clean an additional 16 existing culverts, and remove 1 out-of-service culvert. Existing granite culverts are being replaced with new precast concrete structures. The new precast culverts meet the Massachusetts Stream Crossing Standards, so most will be large enough for wildlife, including foxes and other small mammals to safely pass through.

As part of the culvert improvements project, MassDOT has been working closely with the City of New Bedford on the Tarkiln Hill Road grade crossing. The crossing will receive critical roadway drainage improvements that are necessary to prepare for follow-on rail construction and future Phase 1 service. The work is being coordinated and scheduled ahead of a City of New Bedford roadway project at King’s Highway.

This project also includes constructing six wetlands impact mitigation areas adjacent to the railroad right-of-way. The original estimate for wetlands impact in the South Coast Region was over 2 acres, but the final design team was able to reduce the impacts to less than ½-acre. The final mitigation was developed during the state and federal environmental process and specified in the MA Department of Environmental Protection Section 401 Water Quality Certificate issued for the Phase 1 work.

As additional project mitigation, MassDOT has agreed to provide excess granite from the old culverts to the MA Division of Marine Fisheries to be repurposed in creating off-shore reefs off Cape Cod to improve fisheries habitat. The total area of wetland mitigation is 1.5 times greater than the impacted area in all of Phase 1, and when completed at the end of 2019, the areas will satisfy the state-regulated wetland impact mitigation requirements for the culvert repair work and all of SCR Phase 1.
