SPS is milling and paving nightly with Brox Industries, Inc. in the central artery tunnel of Boston. The work window is typically 4 hours nightly and all of the milled Microsilica wearing surface is replaced with new pavement on a nightly basis. We’re expecting to have a few thousand tons of pavement installed by the end of this year.

Green Line D-Branch: September Update
Coming back to where it all started, the Railroad-SPS JV recently completed a 9-day shutdown on the MBTA Green Line D-Branch in early September. Our crews worked day and night to finish full depth replacement of a #5 and a #6 crossover at Fenway Station, including an additional 200 feet of full depth track replacement outside the turnouts. During the surge, our team also installed 1,400 new timber ties, 2,600 feet of rail, shot 23 thermite welds, and tamped almost 10,000 feet of track structure.
In addition, this surge marked the beginning of our work with Fischbach & Moore Electrical Group to install the MBTA’s new GLTPS system across the Green Line. Their electricians installed 128 new anchor assemblies and around 22,000 ft of new power supply cable, all while working in coordination with the ongoing track repairs.
All work was completed thanks to continued support from the City of Boston, Town of Brookline, and various MBTA Departments.

New Bedford I-95 and Route 18 Interchange Project Update: November 2025
In late August, the DWW-SPS JV implemented our Phase 1 Temporary Traffic Control Plan on I-195 in New Bedford. The traffic control plan shifted the two lanes of traffic on I-195 Eastbound and Westbound into the right shoulder, and temporary barrier was installed to provide a work zone in the median. The DWW SPS JV has spent the last two months reconstructing the median on I-195 to create a crossover that moves the two lanes of I-195 Westbound Traffic onto I-195 Eastbound. This crossover is anticipated to be completed in November, and demolition of the I-195 Westbound bridge will follow.
Additionally, the I-195 Eastbound Ramps to Route 18 were closed to vehicular traffic on September 8th. Demolition I-195 Eastbound Off Ramp to Route 18 SB is underway and nearly complete at this time.
Newton-Weston I-90/I-95 Interchange – Rapid Replacement Weekends
This summer, the SPS-Walsh JV Team at the Newton/Weston I-90/I-95 Bridge Bundle project successfully completed a rapid bridge replacement of the Mass Pike (I-90) over MBTA Railroad.
The rapid bridge replacement was completed over two (2) separate 55-hour weekend shutdowns which included reducing I-90 traffic down to one (1) single lane each direction and full closure of the MBTA Railroad.
The scope of work included complete demolition of existing bridge superstructure, backwall concrete repairs, installation of precast bridge units, placement of rapid-setting concrete batched by on-site volumetric mobile mix trucks, milling, and paving of roadway approaches.
Both weekend bridge replacements were completed ahead of schedule with early opening of I-90 to all travel lanes prior to the 5AM Monday morning rush hour and no impacts to the return of Commuter Rail service.
This video by Savanna Media documents the process and the planning that went into the two rapid replacement weekends.
