Did the Promenade almost become a six-lane highway? If you caught the headlines out of City Hall on August 24, that's the question most Brooklyn Heights residents actually wanted answered, and it's a fair one. Every few years, a new mayor announces a plan to fix the crumbling stretch of highway that runs beneath the walkway where you take your evening lap, and every few years, the plan sounds like it might cost you the walkway itself. This time it doesn't, and understanding why matters more than the price tag.
What actually got announced
On Monday, August 24, Mayor Zohran Mamdani and NYC DOT Commissioner Mike Flynn unveiled a $4 billion, decade-long plan to rehabilitate BQE Central, the 1.5-mile, city-owned stretch of the Brooklyn-Queens Expressway between Atlantic Avenue and Sands Street. Tucked inside that stretch is the 0.4-mile triple cantilever, the three-tiered structure that carries the highway with the Brooklyn Heights Promenade sitting on top and Furman Street running beneath. The structure is roughly 70 years old, built under Robert Moses to carry a fraction of the roughly 130,000 vehicles, including about 13,000 trucks, that use it every day now.
The word doing the heavy lifting here is rehabilitation, not rebuild and not replacement. DOT plans to repair the highway deck, joints, and structural elements, improve drainage and lighting, and keep the road at two lanes in each direction rather than widening it. To keep that traffic off local streets during the work, the city will build a temporary two-level bypass above Furman Street, running from Atlantic Avenue to Columbia Heights, with a second elevated bypass carrying Queens-bound traffic north toward the Manhattan Bridge approach. Construction isn't expected to break ground until 2030, wrapping up around 2040 and extending the highway's life to roughly 2080.
The scenario everyone remembers, and why this one is different
If you've lived here more than a few years, you remember the 2018 version of this fight. That plan, floated under the de Blasio administration, would have built a temporary six-lane highway in the exact footprint of the Promenade, closing it entirely for six years while the underlying structure was repaired. The estimated cost ran $3.2 to $3.6 billion, and the backlash from residents, elected officials, and Brooklyn Bridge Park itself was loud enough to send DOT back to the drawing board.
The plan announced this August is a direct response to that backlash. The new bypass will run over Furman Street at a height no taller than the existing Queens-bound roadway, narrower than the highway it's replacing during construction, at roughly 28 feet wide, widening to about 40 feet near the Atlantic Avenue on-ramp. It won't touch the Promenade's footprint. The Promenade itself is still technically part of the triple cantilever, so it has to be reconstructed along with everything else beneath it, but DOT's stated commitment is that portions of the walkway will remain open at all times during construction, to the extent feasible. That same language covers the parks below.
What changes, and what doesn't, right now
For anyone weighing what this means for a Saturday walk or a Tuesday dog run, the honest answer is: nothing yet, and not for years.
- The Promenade, all 1,826 feet of it, is open exactly as it's always been. Construction hasn't started and isn't scheduled to until 2030.
- Squibb Park, Hillside Dog Park, and Harry Chapin Playground are unaffected today. DOT has said it will maintain access to all three during the work, though Harry Chapin Playground will eventually be reconstructed alongside the Columbia Heights overpass rehab.
- The current phase of the project is environmental review, not construction. The plan enters the city's CEQR process this fall, with an environmental impact statement expected in the summer of 2028.
- DOT is holding two virtual public Q&A sessions before the formal comment period opens, on Tuesday, October 6 from 7 to 8 p.m. and Thursday, October 22 from 11 a.m. to noon. Registration links were still being finalized as of this writing, so keep an eye on DOT's BQE Central project page for details.
The reactions worth paying attention to
The neighborhood's response has been more measured relief than celebration, which tells you something about how bruised this community is from a decade of false starts. Lara Birnback, executive director of the Brooklyn Heights Association, called the decision to keep the footprint unchanged and hold the line at two lanes a positive, while still voicing concerns about the bypass concept itself, a design she noted has been "repeatedly rejected by the community" in past rounds. Council Member Lincoln Restler, State Senator Andrew Gounardes, and Assembly Member Jo Anne Simon issued a joint statement welcoming the shift toward rehabilitation over replacement while flagging that the announcement is "the beginning of a multi-year approval process" with plenty left to resolve.
Not everyone is satisfied with what the plan leaves out. Kelly Carroll, executive director of the Atlantic Avenue Business Improvement District, pointed out that the plan doesn't touch the interchange where the BQE meets Atlantic Avenue, a ramp geometry she says was "designed during the Great Depression" and remains genuinely hazardous for the families who cross it daily on foot to reach Brooklyn Bridge Park. Reworking those interchanges would trigger a federal review the city is trying to avoid, so for now that fix sits outside the scope of this project. It's a reminder that a rehabilitation plan solves the structural problem without solving every problem, and residents who use that Atlantic Avenue crossing regularly should expect that particular frustration to persist for a while longer.
Life on the Promenade doesn't pause for any of this
While the environmental review grinds forward on its own multi-year timeline, the calendar in front of you hasn't changed. Brooklyn Bridge Park closes out its Movies With a View season on Friday, September 18, with a screening of How to Train Your Dragon at Pier 1's Harbor View Lawn, the only Friday and family-oriented entry in a series that otherwise runs Thursdays. The Harvest Festival follows on Saturday, October 17, from 11 a.m. to 3 p.m. at Pier 6, with live music, storytelling, and lawn games marking the season's last big free event. And if you've got a dog who's used to Hillside Dog Park, DUMBO's Halloween tradition returns on October 31, with a march to the Archway followed by the Howl-O-Ween dog costume contest, the kind of small, specific ritual that only makes sense if you already live close enough to walk to it.
None of that changes because of what was announced in August. If anything, the timeline argues for the opposite conclusion: the version of Brooklyn Heights you know today, walkway included, holds steady for at least the next few years while City Hall and the community work through a review process that's designed to be slow on purpose.
What to actually do with this information
If you live here, the practical move is simple: mark the October 6 and October 22 Q&A dates if you want a direct line to DOT before the formal comment period opens, and treat everything else as background noise for now. The Brooklyn Heights Association has been the most consistent source of updates through every round of this fight since 2016, and they'll keep flagging the moments that matter as the CEQR process unfolds.
For a neighborhood that's spent the better part of a decade bracing for the worst version of this project, the current plan is proof that showing up to public meetings and writing joint letters actually shapes outcomes. That's worth remembering the next time a DOT presentation lands in your inbox.
