#subwayextension

Lead

The second phase of the Second Avenue Subway project is reconnecting East Harlem to the subway system after more than eight decades. This New York Subway Extension will see the Q Line extend north from 96th Street to 125th Street, adding three new stations to reduce congestion and improve daily mobility for commuters.

This artistic rendering shows what the new 125th Street station will look like once Phase 2 of the Second Avenue Subway expansion is complete. Designed to reconnect East Harlem with rapid transit after decades, the station blends modern architecture with public space — offering easy access, pedestrian-friendly streets, and seamless connections to buses and other transit options.

Architectural and Design Details

Tunnels and Stations

The project involves 1.5 miles of twin tunnels, with station shells at 116th and 125th Streets. The design accommodates high passenger volumes while maintaining structural integrity. The New York Subway Extension reuses part of an existing tunnel from previous construction, enhancing both efficiency and sustainability.

Behind every tunnel and track, there’s a team — and a community. This moment captures the spirit of collaboration behind bringing the Q line to East Harlem. From planners to neighbors, everyone’s voice helped shape this historic project — because building transit isn’t just about concrete and steel… it’s about people, too. Above-Ground Structures and Ancillary Functions

The project also includes above-ground buildings to house ventilation, mechanical, and electrical systems. Ground-floor spaces are designed to potentially support retail or community uses, integrating the infrastructure with the surrounding urban environment.

Business planning by metro engineers Project Significance

This phase represents a critical step in the New York Subway Extension, restoring rapid transit to East Harlem, improving daily commuting for thousands of riders, while addressing the technical and environmental challenges of building underground in a dense city setting.

✦ ArchUp Editorial Insight

The project extends the Q Line to reconnect East Harlem with rapid transit after more than eight decades. The New York Subway Extension's spatial composition emphasizes twin tunnels and new station shells at key streets, accompanied by above-ground ancillary structures for ventilation and mechanical systems, reflecting attention to sustainability and urban integration. Yet, while the design is functional and coherent, the impact on daily passenger experience remains modest, with limited visual interaction between interior and exterior spaces. Nonetheless, the extension provides a framework for enhancing urban mobility and redefining spatial dynamics, offering a future-oriented model for integrated infrastructure development.
