Skanska, Others Complete $395M Renovation of Pennsylvania Station Concourse
Construction on the project began in January of 2021 and the team achieved substantial completion in March 2023.

The project, awarded to Skanska, AECOM, and Skidmore, Owings & Merrill (SOM) by Penn District Station Developer LLC in 2020, aimed to modernize and widen LIRR’s 33rd Street train hall corridor, while maintaining the station’s daily operations and train service.

Skanska, a global construction and development firm, and AECOM announced the completion of the $395 million renovation of Pennsylvania Station’s Long Island Railroad (LIRR) Concourse.
The project, awarded to Skanska, AECOM, and Skidmore, Owings & Merrill (SOM) by Penn District Station Developer LLC in 2020, aimed to modernize and widen LIRR’s 33rd Street train hall corridor, while maintaining the station’s daily operations and train service.
In partnership with Skanska, who served as Design Builder, AECOM served as Designer of Record, providing design, engineering, vertical transportation, and project management services, and worked closely with Lead Architect Skidmore, Owings & Merrill (SOM) to expand the height and width of the LIRR concourse.
“The most heavily used concourse of America’s busiest train station has been entirely transformed, both visually and functionally. The improvements make commuting more convenient, while also allowing this transit hub to have the capacity and accessibility to meet New York’s growing transportation needs,” said Thomas Prendergast, AECOM’s New York Metro executive. “We’re proud to have worked with the MTA and our partners to broaden and revitalize the concourse while also minimizing impacts to LIRR commuters and the station’s operations.”
Pennsylvania Station’s Long Island Railroad (LIRR) Concourse Improvements
The 27-month design-build project encompassed both the design and construction of the reimagined concourse, with a widened corridor, raised ceiling heights, upgraded lighting and wayfinding, new digital information screens, improved mechanical and electrical systems, and new architectural finishes, among other station enhancements.
The renovation also improves safety and ADA access from the street to the concourse via a new elevator on 33rd Street, as well as from the concourse to the platforms with rebuilt stairs and handrails, new enclosures for fire protection, and a replacement elevator.
"In order to best accommodate and enhance the commuting experience for the 600,000 passengers that utilize LIRR’s 33rd Street corridor daily, deciphering a path to improving the station’s circulation and traffic flow without disrupting daily train service was paramount,” said Michael Viggiano, EVP of Skanska’s East Coast civil operations. “We’re thrilled to be celebrating the completion of this project and to have played a crucial role in reconstructing one of New York City’s most highly trafficked transit hubs.”
Phases of the Project
The first phase of this project, the East End Gateway, brought sunlight to the subterranean concourse for the first time in decades on the final day of 2020.
“We worked closely with the design-build team to create a new center of gravity for Penn Station and the LIRR,” said SOM Partner Colin Koop. “The concourse design introduces a clear connection to Seventh Avenue and simplifies the flow of foot traffic between the street, the subways, and the LIRR—helping travelers easily navigate the station, all in an expansive space filled with light.
Construction on the project began in January of 2021 and the team achieved substantial completion in March 2023.
Skanska, AECOM, and SOM partnered to deliver the East End Gateway, an iconic new entrance on the east side of Penn Station at 33rd Street and Seventh Avenue. Skanska and SOM also led the design and construction of Moynihan Train Hall, which transformed the historic Farley Building into a landmark extension to Penn Station.
Both projects were completed in 2020.
