For the better part of three years, Brooklyn Heights residents filed into public workshops to look at renderings of a different Promenade edge. The Department of Transportation walked neighbors through three named concepts for the triple cantilever section: the Terrace, the Lookout, and the Stoop. The Stoop was the one people talked about afterward. It was the only design that would have carved a direct, staircase-like connection from the Promenade down to Brooklyn Bridge Park, cascading green space where the highway now sits in three stacked layers. People asked about sightlines, retaining walls, whether the roadway could drop to a single level. The process ran workshop rounds through 2023 and into the spring of 2024, covering everything from the Atlantic Avenue interchange to the Manhattan Bridge approach.
Then, on August 24, 2026, Mayor Zohran Mamdani stood with NYC DOT Commissioner Mike Flynn and announced a plan for that same stretch of highway. It isn't the Terrace. It isn't the Lookout. It isn't the Stoop.
What Actually Got Announced
The plan is a rehabilitation, not a redesign. DOT will repair the deteriorating triple cantilever, upgrade drainage, railings, and lighting, and keep the highway at its current two lanes in each direction. No widening, no altered interchanges. To do the work, the city will build a temporary two-level bypass on top of Furman Street, running from Atlantic Avenue to Columbia Heights, sitting no higher than the existing Queens-bound roadway and staying clear of the Promenade above it. A second elevated bypass will carry traffic from Columbia Heights, over the Brooklyn Bridge approach, to the Manhattan Bridge. The project is priced at roughly $4 billion, with construction breaking ground in 2030 and running about a decade.
The detail that matters most if you live here: the Promenade stays open, and stays intact, through all of it. That's a real departure from the plan a previous administration floated in 2018, which would have shut the walkway down and put a temporary six-lane highway on its deck for years. This time, none of that surfaces.
The Concepts That Didn't Make the Cut
What also doesn't surface is any of the green space or park-connection work that filled those 2022 through 2024 workshops. The city's own project page now describes the scope in plain terms: repair the existing structure, keep it at two lanes, don't expand the footprint. The multi-year visioning process that produced the Terrace, Lookout, and Stoop concepts is listed on its own site as complete, with the current announcement pointing residents toward nyc.gov/bqe for what's next.
Lara Birnback, executive director of the Brooklyn Heights Association, put the gap plainly, calling the approach "retrograde" and "a throwback" when asked about it by Streetsblog days after the announcement. Her frustration wasn't about disruption. It was about scope. The neighborhood spent years imagining a different relationship between the Promenade and the park beneath it. What got announced imagines the same highway, repaired.
The neighborhood isn't starting from zero on park connections. The Squibb Park Bridge already links the Promenade to Brooklyn Bridge Park, though it had to be rebuilt in 2019 and 2020 after structural problems of its own. The Stoop concept would have added a second, more direct crossing closer to the triple cantilever itself. That piece isn't part of the current scope.
Why the City Is Moving Now Instead of Later
The urgency isn't cosmetic. According to the mayor's office, the structure is 20 years past its design life and carries roughly 130,000 vehicles a day, more than double what it was built to handle. City Hall's own estimate puts the cost of continued delay at $160 million a year in escalation alone, and warns that a shutdown of the cantilever would force all 13,000 of its daily truck trips onto local streets, the same streets that run past brownstones on Hicks, Henry, and Willow. That's the argument for moving now rather than waiting for a more ambitious design to clear funding and approvals. It's also the argument Birnback herself seemed to land on days later, in a separate conversation with Brooklyn Paper, when she said she was "excited, let's get this going again," adding that maybe the third attempt at fixing this stretch of highway would be the one that sticks.
What Doesn't Change Before 2030
If you live in Brooklyn Heights, the honest answer is: not much, for a while. Construction doesn't begin until 2030. Between now and then, the project has to clear the City Environmental Quality Review process, which studies effects on traffic, noise, air quality, parks, and historic resources before anything gets built. DOT expects to complete that review's Environmental Impact Statement by the summer of 2028. Your walk on the Promenade this fall looks the same as it did last fall.
What does open up this fall is your window to weigh in before the design locks in further. DOT has scheduled two virtual Q&A sessions ahead of the formal comment period:
- Tuesday, October 6, 2026, 7:00 to 8:00 p.m.
- Thursday, October 22, 2026, 11:00 a.m. to 12:00 p.m.
Formal CEQR public scoping meetings, where comments are entered into the official record, are expected later this fall, with dates to be posted at nyc.gov/bqe. DOT has also said it will hold in-person pop-up events where residents can review materials and talk to the project team directly.
Who's Already Asking Questions
Not everyone is satisfied with what's in scope, and the questions are specific rather than general. Kelly Carroll, executive director of the Atlantic Avenue Business Improvement District, told Brooklyn Paper she was hopeful when she first saw headlines about the plan, then frustrated to learn it doesn't touch the interchange ramps, including what she described as a particularly hazardous exit at Atlantic Avenue. Council Member Lincoln Restler, State Senator Andrew Gounardes, and Assembly Member Jo Anne Simon issued a joint statement calling the cantilever a relic of Robert Moses-era planning and expressing hope that this rehabilitation becomes an interim step toward eventually retiring the highway altogether, rather than a 40-year commitment to the status quo. One Brooklyn Heights resident, Michael McCabe, told CBS New York the coming years would bring "a lot of problems for the people who live here or have to commute through this area."
None of these are objections to fixing the structure. They're arguments about what else should ride along with the fix while the city has the road open and the funding secured.
What This Means If You Live Here
The plan announced in August answers the question that mattered most after 2018: the Promenade isn't closing, and there's no six-lane highway coming to its deck. That's worth knowing on its own. But the years of workshops built an expectation of something more, a physical link between the walkway and the park below, green space where retaining walls now sit. That expectation isn't part of what's currently funded or scoped. If a direct Promenade-to-park connection, or changes to the Atlantic Avenue ramp, matter to how you experience this neighborhood, the two October Q&A sessions and the CEQR scoping period this fall are the actual venue for that conversation, not a formality to skip. The environmental review that follows will shape construction staging and community mitigation for the next decade. It won't reopen the design question once it's underway.
The Promenade will still be there for your evening walk this October, next October, and the one after that. What gets built beneath it starting in 2030 is still, in real terms, being decided right now.
