Park Avenue is getting a massive redesign. Here are all the details and plans.

Park Avenue is about to lose a couple of traffic lanes and gain a whole lot more park.

Yesterday, New York City officials unveiled substantial new plans to redesign one of midtown’s most iconic corridors, turning 11 blocks of Park Avenue into a greener, more pedestrian-friendly stretch filled with wider medians, new seating, landscaping and potentially even bike lanes.

The proposed overhaul would affect Park Avenue between East 46th and East 57th Streets, directly above the massive Grand Central Terminal train shed, which the MTA is already preparing to rehabilitate as part of its 2025–2029 capital plan. Rather than simply patching things up underground, the city wants to use the construction moment to completely rethink the avenue above it. 

The biggest physical change? The city would remove one lane of traffic in each direction to dramatically widen the avenue’s medians. Those newly expanded spaces could include plantings, public seating, pedestrian walkways and north-south bike lanes, along with new crosswalks connecting the medians block by block. 

Renderings released by the city show a much leafier version of Park Avenue, with people lounging under trees, cyclists gliding through protected lanes and office workers actually sitting outside instead.

“With this new redesign, we are putting the ‘Park’ back into Park Avenue and upgrading Midtown Manhattan by providing residents and visitors alike with more usable public space,” Mayor Zohran Mamdani said in a statement announcing the proposal. 

DOT commissioner Mike Flynn added: “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.” 

The redesign has apparently been years in the making. According to the city, the concepts were shaped through surveys, workshops, stakeholder meetings and conversations with community boards and local organizations. The project is also tied to the broader East Midtown rezoning plan, which requires new commercial developments nearby to contribute funding toward public realm improvements. 

That timing feels especially notable, given that the skyline around Park Avenue has already been rapidly transforming thanks to giant new office towers like JPMorgan Chase’s 270 Park Avenue headquarters and the ongoing redevelopment wave sweeping midtown East.

Before anything gets finalized, though, New Yorkers will get a chance to weigh in. The city is hosting a series of public workshops and community board meetings over the next few weeks, where residents can review the plans and offer feedback.

For a street literally called Park Avenue, this may be the most park it has looked in decades.
