If you’ve ever watched a crosstown bus creep down Madison Avenue at a pace that makes walking feel faster, you know the frustration. The good news: it’s changing. The New York City Department of Transportation has officially kicked off construction on a long-awaited extension of double bus lanes along Madison Avenue — and if you ride the M1, M2, M3, M4, or Q32, this is the policy update you’ve been waiting for.
Construction began in late April 2026, after a previous version of the project was put on pause under the prior administration. Mayor Zohran Mamdani’s team committed to completing the redesign within weeks, weather permitting. The work adds double bus lanes along one of Midtown’s most congested north-south corridors, stretching from East 42nd Street south to East 23rd Street — a 19-block span that sees some of the highest bus ridership in the city.
What’s Actually Changing on the Street?
The Madison Avenue redesign isn’t a one-size-fits-all change. NYC DOT has laid out a block-by-block configuration that balances bus priority with parking and car traffic access. Here’s how it breaks down:
Between East 23rd and East 34th Streets, the design preserves a parking lane while incorporating left-turn pockets to ease cross-street traffic. Between East 34th and East 42nd Streets, a combined parking and rush-hour travel lane will be active — meaning the space serves parkers during off-peak hours but converts to a moving lane during the morning and evening rush. Along the full 19-block corridor, two dedicated bus lanes will run alongside a single general travel lane, giving buses a protected path for the first time on this stretch.
Before double bus lanes were installed on neighboring Fifth Avenue, Madison Avenue buses averaged just 4.5 miles per hour in peak hours — slower than a New Yorker walking at a clip. After the Fifth Avenue redesign, local bus speeds improved by 6 to 12 percent, with express bus speeds jumping 11 to 20 percent. City officials expect similar results on Madison once the lanes are operational.
Who Rides These Buses — and Who Benefits?
NYC DOT estimates nearly 100,000 daily riders use the bus routes that travel along this segment of Madison Avenue. The M1 runs between the Upper East Side and the Financial District; the M2, M3, and M4 cover various uptown-to-midtown routes; and the Q32 serves as an express connector between Jackson Heights, Queens and Midtown Manhattan. All of these routes will benefit from the redesign.
For residents in neighborhoods along the corridor — Gramercy Park, Kips Bay, Murray Hill, and Midtown East — the change means faster and more predictable bus service to Grand Central Terminal at 42nd Street, the cluster of hospitals around 34th Street, and major employment centers throughout Midtown. Visitors traveling to Murray Hill hotels, the Morgan Library at 225 Madison Avenue, or shopping destinations in the Herald Square area at 34th Street will also find the bus a more competitive option compared to rideshare or cab.
The Mamdani Administration’s Streets Vision
The Madison Avenue project sits within a broader city strategy to redesign key streets for transit priority, cycling, and pedestrian safety. Under Commissioner Mike Flynn, NYC DOT has described its mission as delivering on the “vision of the Streets Plan” — a multi-year initiative that reimagines how street space is allocated across all five boroughs.
The Madison project is notable because it restarts work that had stalled under the previous DOT leadership. Mamdani’s administration made clear early on that completing this project was a priority — part of a push to make transit competitive with driving on the city’s most congested corridors.
Madison Avenue isn’t the only Manhattan street seeing action this spring. DOT is also pursuing protected bike lanes on other key corridors, and the Midtown South Mixed-Use Plan — which rezoned 42 blocks between West 23rd and West 40th Streets to allow residential conversions of office buildings — will bring new residents to the very area the Madison Avenue bus serves. More people living in the corridor means more demand for exactly this kind of transit investment.
What About Drivers, Deliveries, and Parking?
Whenever DOT announces bus lane construction in Midtown, questions from drivers and business owners follow quickly. The new design does preserve parking access on parts of the corridor — specifically maintaining a parking lane between 23rd and 34th Streets, and off-peak parking availability between 34th and 42nd Streets. Delivery and curbside loading will remain permitted during non-rush periods.
DOT has pointed to Fifth Avenue’s experience as evidence that the feared negative effects for nearby businesses often don’t materialize. After the Fifth Avenue lane installation, foot traffic to nearby retailers held steady, and through-traffic adjusted. The agency expects a similar adjustment period on Madison before ridership gains become fully apparent.
Once construction is complete, the lanes will be enforced by the city’s automated bus lane camera system. Vehicles found blocking bus lanes during active hours — typically posted as 7 a.m. to 7 p.m. daily — will receive violation notices. The exact hours for the Madison Avenue lanes will be posted by DOT when the project is completed.
