Grand Army Plaza is the grandest entrance to any park in America, yet we treat it like a glorified traffic circle. It's a chaotic mess of asphalt where cyclists dodge SUVs and pedestrians sprint for their lives under the shadow of the Soldiers' and Sailors' Arch. State Assembly Member Zohran Mamdani recently threw his weight behind a growing movement to ban cars from the plaza entirely. He isn't just making a political statement. He's pointing out an obvious truth that New York City planners have ignored for decades.
The plaza sits at the intersection of Flatbush Avenue, Vanderbilt Avenue, Eastern Parkway, and Prospect Park West. It handles roughly 50,000 vehicles a day. That sounds like a lot until you realize how little of that space actually serves the people living near it. Right now, the area is a series of "islands" separated by rivers of fast-moving metal. If you want to get from the Sunday Greenmarket to the actual park entrance, you have to navigate multiple lights and hope a turning taxi sees you. It's exhausting. It’s loud. It’s unnecessary.
Why the Current Design Fails Everyone
We’ve been told for years that Grand Army Plaza is a vital "release valve" for Brooklyn traffic. That’s a myth. When you prioritize through-traffic in the heart of a residential and cultural hub, you don't solve congestion. You just invite more of it. This is a phenomenon urban planners call induced demand. By making it "easy" to drive through the plaza, the city encourages more people to get behind the wheel, clogging up the very streets they’re trying to navigate.
Safety is the biggest casualty here. Between 2017 and 2022, there were hundreds of crashes in this small radius. We aren't talking about fender benders. We're talking about life-altering collisions involving kids on bikes and seniors crossing the street. The Department of Transportation (DOT) has made some tweaks, like adding plastic bollards and paint, but those are Band-Aids on a gunshot wound. You can’t paint your way out of a design that fundamentally treats humans as obstacles to commuters from Long Island.
Mamdani’s proposal aligns with a vision of "Paris on the Hudson." Think about the Place de la République or the Arc de Triomphe. Paris didn't just wake up one day and decide to be walkable. They made a choice to reclaim the streets. They kicked cars out of historic centers and watched their local economies thrive. Brooklyn deserves that same level of ambition.
The Economic Reality of a Car Free Plaza
Business owners often freak out when you mention removing parking or closing lanes. I get it. They're worried about deliveries and customers who drive in. But look at the data from the 14th Street Busway or the car-free stretches of Broadway in Manhattan. When you make a space pleasant for people to exist in, they stay longer. They spend more money. A person in a car at 30 miles per hour isn't stopping for a coffee or browsing a local bookstore. A person walking through a park-like plaza is.
Grand Army Plaza is surrounded by some of the most iconic institutions in the city. You have the Brooklyn Public Library, the Brooklyn Museum, and the Botanical Garden. These are world-class destinations. Currently, the experience of visiting them is marred by the roar of Flatbush Avenue. Imagine a continuous green carpet extending from the library steps all the way into Prospect Park. You could have outdoor seating, permanent market stalls, and performance spaces where there is currently just idling rubber.
Addressing the Traffic Displacement Fear
The most common argument against Mamdani’s plan is that the cars won't disappear; they’ll just move to side streets. It’s a fair concern, but it’s often overstated. When the city closed portions of Central Park to cars, critics predicted a total meltdown of the Upper West Side. It didn't happen. Drivers adapted. Some switched to the subway, others took different routes, and some just stopped making unnecessary trips.
New York’s grid is resilient. The goal of a car-free Grand Army Plaza isn't to trap people in their neighborhoods. It's to stop the "cut-through" culture that treats Brooklyn as a highway. If we make driving slightly less convenient while making transit and cycling significantly better, we win. Mamdani has been vocal about the need for better bus service to accompany these changes. You can’t just take away the road; you have to give people a real alternative.
The MTA’s ongoing bus network redesign is the perfect partner for this project. By prioritizing the B41 and other local routes with dedicated lanes that bypass the plaza chaos, we actually make the commute faster for the thousands of people who rely on public transit every single day.
A Moral Argument for Public Space
Parks are the lungs of our city. Prospect Park was designed by Frederick Law Olmsted and Calvert Vaux to be a sanctuary. Grand Army Plaza was intended to be the "parlor" of that sanctuary. Instead, we’ve turned the parlor into a parking lot.
There’s an equity issue here too. A huge chunk of Brooklyn households don't own cars. Why are we dedicating the majority of our most valuable public land to a minority of residents and people just passing through? It’s a waste of space. By opening the plaza, we create a massive new public square for protests, celebrations, and daily life. We saw a glimpse of this during the 2020 protests when thousands gathered at the arch. It felt like the plaza finally found its purpose. It shouldn't take a global movement for us to realize that people belong in plazas, not cars.
Moving Beyond the Pilot Program Mentality
The city loves "pilot programs." They’ll close a street for a weekend, call it a success, and then go back to the status quo. We don't need a pilot for Grand Army Plaza. We need a permanent, structural change. This means tearing up the asphalt and replacing it with pavers, trees, and benches. It means rerouting the heavy traffic flow of Flatbush Avenue around the perimeter or through a more sunken, separated channel that doesn't bisect the pedestrian experience.
Assembly Member Mamdani’s support gives this movement the legislative teeth it needs. It signals to the DOT and the Mayor’s office that there is political cover to be bold. Political courage is rare in New York transit politics. Usually, everyone waits for a consensus that never comes. But the consensus is already there among the people who actually use the park. They want a space where their kids can run without a parent clutching their hand in a death grip.
If you want to see this happen, stop waiting for the city to suggest it. Call your local representatives. Join groups like Transportation Alternatives or the Prospect Park Alliance. Attend the community board meetings where these plans usually go to die. The "car-free" label sounds radical to some, but in twenty years, we’ll look back and wonder why we ever let cars ruin such a beautiful place to begin with.
Start by looking at the maps provided by local advocacy groups. They show exactly how the traffic can be diverted without breaking the borough. Study the success of the 34th Avenue Open Street in Queens. It’s the gold standard for what happens when you prioritize humans. Then, demand that same standard for Brooklyn’s most important intersection. We have the space. We have the vision. We just need to stop letting the status quo drive the bus—or in this case, the SUV.
