New York City officials have unveiled early design concepts to reimagine Park Avenue in Midtown Manhattan as a greener, more pedestrian-focused corridor, part of a broader plan to align street-level improvements with major infrastructure work underway below ground.
Mayor Zohran Mamdani and New York City Department of Transportation Commissioner Mike Flynn on Thursday presented proposals that would expand Park Avenue’s medians, add landscaping and seating, and explore new pedestrian and cycling amenities along an 11-block stretch from 46th Street to 57th Street.
The corridor sits directly above the Grand Central Terminal train shed, which is undergoing a major rehabilitation by the Metropolitan Transportation Authority’s Metro-North Railroad. City officials said the timing creates an opportunity to coordinate surface-level redesign work with infrastructure upgrades below.
“With this new redesign, we are putting the ‘Park’ back into Park Avenue,” Mamdani said. “Our city’s public spaces must better serve the public.”
Design concepts remove one travel lane in each direction to allow for expanded medians featuring plantings, seating areas and pedestrian connections. The design also includes new crosswalks linking medians along the corridor.
The redesign is intended to balance the needs of pedestrians, cyclists and drivers while improving safety and usability in one of Midtown’s busiest corridors. A typical median concept under study includes landscaped areas, pedestrian pathways and a potential north-south bike lane integrated into the corridor’s redesign.
“Whether you’re walking, biking or just looking for a place to sit and take a break, this project is about making Park Avenue work better for you,” said NYC DOT Commissioner Mike Flynn, adding the project aims to activate underused space.
Concepts were developed through extensive community engagement, including public surveys, stakeholder interviews, workshops and meetings with community boards and local organizations. The planning process is funded through the East Midtown Governing Group, established under the 2017 Greater East Midtown rezoning, which requires new commercial developments to contribute to public realm improvements in the area.
An ongoing train shed rehabilitation is part of the MTA’s 2025–2029 capital plan. Officials said coordination between the city and transit agency is intended to minimize disruption while aligning long-term infrastructure and surface improvements.
NYC DOT will host several public events and meetings to gather feedback on the proposed redesign:
Public outreach events
- Saturday, May 2, 2026
- 10 a.m.–12 p.m. — St. Bartholomew’s Church (50th Street & Park Avenue)
Community Board meetings
- Manhattan Community Board 6: May 4, 2026, 7 p.m. (virtual)
- Manhattan Community Board 5: May 28, 2026 (details forthcoming)
City officials said the outreach process will help refine the final design before any construction timeline is set.
