Skanska-Traylor-Walsh JV awarded $1.02B contract for Second Avenue Subway Phase II Project in New York
New York, New York – The joint venture of Skanska, Traylor Bros., Inc., and Walsh Construction has been selected by the Metropolitan Transportation Authority (MTA) to deliver design-build services for the $1.02 billion, Phase II of the Second Avenue Subway project in New York, NY. The project will extend the Second Avenue Subway (Q line) to 125th Street and includes construction of new station structures for the future 106th Street Station. Phase II design services will be led by Mott MacDonald.
“Alongside our joint venture partners, Skanska and Traylor Bros., we’re focused on delivering Phase 2 of the Second Avenue Subway Project through coordinated design-build execution,” said Jeff Twidwell, senior vice president of Northeast Transportation at Walsh Construction. “We look forward to extending Q service in Manhattan through disciplined planning and close coordination with stakeholders, while adhering to the highest standards of safety and quality.”
The project scope includes designing and constructing new subway station structural shells between 105th Street and 110th Street to accommodate the future 106th Street Station. It also includes construction of the structural tie-ins to existing tunnels, support of excavation and earthwork, installing roadway decking to maintain existing traffic, building at- and below-grade structures for two station entrances, and utility support and reconstruction.
Phase II will extend the Q line into East Harlem and Harlem, improving connectivity and reducing commute times with new stations at 106th Street and 116th Street on Second Avenue, as well as a terminal station at 125th Street and Lexington Avenue that will serve as a key transfer point to the 4/5/6 lines and Metro-North. Once complete, the Second Avenue Subway will create a continuous two-track corridor from 125th Street to Lower Manhattan, with connections to West Midtown and Brooklyn, expanding transit access for East Side residents, workers, and visitors while also easing long-standing congestion on the nearly 100-year-old Lexington Avenue Subway Line.
“We’re proud to have been selected for the second phase of the Second Avenue Subway, which will significantly improve mobility for New Yorkers by expanding Q line access into East Harlem and Harlem,” said Michael Viggiano, executive vice president of Skanska USA Civil. “Building on the successful completion of Phase I in 2017, we are honored to continue our involvement in this transformative program and to help deliver faster, more reliable transit options that better connect communities across the city.”
“We’re honored to be part of the team selected to advance Phase II of the Second Avenue Subway. Projects like this demand deep underground expertise, strong coordination, and a commitment to working safely in one of the most complex urban construction environments in the country. Continuing our partnership with Skanska on the previously constructed 86th Street Cavern, we’re proud to help build infrastructure that will improve mobility and serve New Yorkers for generations,” said Chris Hebert, vice president of Traylor Bros., Inc.
Construction is expected to reach substantial completion in Q3 2030.
