The Seabrook-Hampton Project Team was busy in May 2026 with finishing the substructure concrete, installing structural steel, hosting Safety Week, and much more. The final pier cap placement was completed to wrap up over 6,000 cy of concrete for all the substructure and 48 out of 78 steel girders have been installed as the superstructure starts to take shape.
In May, the SPS-Walsh JV team placed over 900 CY of concrete, split between multiple bridge decks, bridge barrier, approach slabs, and moment slabs.
Later that month, they worked several overnight shifts, placing the concrete bridge deck for the new I-90 mainline bridge. This placement is one of the many required to complete the current phase of construction and represents a highly coordinated effort by a skilled and experienced team.
Every year, Construction Safety Week is celebrated nationally at the beginning of May. Safety Week 2026 was a true testament to how much SPS values safety. Each day, we had the opportunity to learn more about fall protection, traffic control, confined space, job-specific hazards, and more.
A big thank you to all of our site and project teams that hosted events: the SPS – D.W. White Construction JV Haverhill-Methuen Project Team on Monday, the Marine Yard in Everett on Tuesday, the Seabrook-Hampton Project Team on Wednesday, and the Railroad Construction Company – SPS JV Southampton Yard team on Thursday.
On Friday, SPS hosted Neil Swidey Swidey, author of “Trapped Under the Sea” and editor-at-large at the Boston Globe Magazine. He discussed the 10-mile tunnel leaving Boston, the construction process, and the consequences of the decision-making process.
Thank you to everyone who participated last week and to the Safety Department for putting together an incredible week.
