NEW YORK, NY — The Circulation Improvement at Grand Central-42nd Street Station project has been recognized with an Honor Award from the American Society of Highway Engineers (ASHE) New York Metro Section Project of the Year Awards, which celebrate outstanding transportation infrastructure projects across the region. STV will be honored alongside the project’s owner, the Metropolitan Transportation Authority (MTA) Construction & Development, and the general contractor and the firm’s client, Skanska, for delivering the improvement at one of the busiest transit hubs in the world.

Located beneath East 42nd Street and Lexington Avenue, the project introduced a new pedestrian tunnel directly connecting the No. 7 subway line to Grand Central Terminal’s mezzanine and Lexington Avenue Line platforms. The new connection alleviates long-standing congestion caused by a single constrained exit on the station’s east side — improving circulation, safety, and emergency egress for roughly 40,000 daily riders while supporting more than 500,000 passengers who move through Grand Central each day.

STV served as engineer-of-record, leading multidisciplinary structural, tunneling, geotechnical, and systems engineering for the design-build project, which was delivered under live subway operations and within an exceptionally dense underground environment. Construction required precise coordination to protect active rail lines, historic structures, and critical utilities, while meeting a compressed schedule tied to the opening of Grand Central Madison.

“This recognition is a tremendous honor for our entire team and our partners at MTA Construction & Development and Skanska,” said Hamidreza Rezaei, Vice President and Engineering Director at STV. “Delivering this project beneath one of the busiest transit stations in the world required innovation, precision, and collaboration at every step. The new tunnel not only resolves critical circulation challenges, but also creates a safer, more intuitive experience for the millions of commuters and visitors who rely on Grand Central every year.”
