The plan

Bike boulevards on "the Bergen and Dean Street corridors from Court Street to East New York Avenue in Brooklyn," 10 miles of parallel east-west streets, announced May 6, 2026.

Why these streets. They are "key east-west residential corridors already heavily used by cyclists"; both feed the Brooklyn and Manhattan bridges, and west of Flatbush Avenue there is "far more bike traffic than car traffic". Bergen already has a bike lane in the DOT file on 36 of its 38 blocks and Dean on 26 of its 36, nearly all painted rather than protected; the block table lists each one.
What a bike boulevard may include: "protected bike lanes, sidewalk extensions, medians, traffic-calming measures and pedestrian improvements".
Timeline: the city "plans to release a design proposal later this year, with the first phase targeted for installation in 2027".
What is not decided: "It is even unclear which stretches of the roadways will get the treatment," and "Details of the design have not been finalized".
Coordinated with: the MTA's Brooklyn bus redesign, the Flatbush Avenue busway and the Atlantic Avenue Mixed Use Plan; the bus redesign is what moves the B65.
The safety case the city makes: protected bike lanes cut deaths and serious injuries 18.1 percent overall and 29.2 percent for pedestrians.

What DOT has published

DOT runs the project from three places: a project page, a feedback map where anyone can pin a comment, and the Street Design Manual entry that defines a bike boulevard. As of September 27, 2026, none of them holds a design.

1. The project page

nycdotprojects.info/project/dean-bergen-bike-boulevard-project →

What it says, in full. "NYC DOT is advancing a community-driven, phased project to transform Dean St and Bergen St into safe, comfortable bike boulevards. As key east-west residential corridors already heavily used by cyclists, these streets are well suited for this approach. Bike boulevards are low-speed, low-traffic streets that prioritize bicycle and micromobility travel and pedestrian comfort while maintaining local vehicle access. Design elements may include shared, standard, or protected bike lanes, along with treatments that slow vehicle speeds, reduce through traffic, and improve safety for pedestrians and cyclists, particularly at intersections. The final design will be shaped through ongoing community engagement across multiple project phases.". The page's one image is captioned "Bergen Bike Bus."
What it does not say. As of September 27, 2026 the page has no project limits, no phase list, no schedule, no design drawings, no presentation and no document links; its only tool is the feedback map. The only timeline is the May 6 announcement's. On October 14, 2026 DOT added the first meeting dates: two virtual public workshops, November 10 and 12.
Three design options are on the table. "Shared, standard, or protected bike lanes" is DOT's own range: a shared lane (markings only), a standard painted lane, or a protected lane. Which applies where is what the design proposal will decide; DOT has not said.
"Maintaining local vehicle access" and "reduce through traffic." Those two phrases are the definition of a bike boulevard and they bear on the truck route question: local access stays, through traffic is what the treatments discourage. That bears on Bergen Street's truck route status, which nothing on DOT's page addresses.

2. What "bike boulevard" means in DOT's Street Design Manual

nycstreetdesign.info/geometry/bike-boulevard →

Definition. "A low-traffic, slow street designed to prioritize bicycle and micromobility travel while maintaining local vehicle access," which "incorporates traffic devices and other calming interventions to enhance safety and provide more comfortable conditions for cycling." Bike boulevards "typically span multiple blocks" as "continuous, connected neighborhood routes".
Where DOT uses it. "Generally implemented on non-arterial streets that provide a continuous and direct route for cyclists." The manual marks the treatment's "Usage" as "Limited." The one pictured example is Berry Street in Williamsburg.
The toolkit the manual points to. The entry cross-references the manual's traffic-calming devices: the raised median, the raised speed reducer and the chicane, plus its "Designing for Micromobility" section. Those are the kinds of physical changes "treatments that slow vehicle speeds" on the project page can mean. The entry does not name diverters (barriers that stop through traffic at an intersection); the project page's "reduce through traffic" is the only reference to that idea on either page.
Benefits the manual claims. Safety "through reduced vehicle speeds and clearly signed networks"; mobility by "linking schools, parks, transit, workplaces, and commercial areas"; and less congestion "by limiting non-essential vehicle trips".
Its own cautions. Plan the connections to schools, parks, shops and transit; schedule regular maintenance; and "maintain emergency vehicle access at all times".

3. The feedback map

nycdotprojects.info/project-feedback-map/dean-bergen-streets-feedback-map

Comment on DOT's feedback map →

What it is. DOT's public comment map for this project: "We want to hear from you! Provide comments by choosing a focus area below and following the instructions that pop up. Please be as specific as you can." A commenter picks a category, drops a pin on the map or names a corner or a block, and writes a comment. Comments are public; they "are reviewed and, while comments will not be edited by NYCDOT personnel, a comment may be blocked if it violates the comment policy". No opening or closing date is posted.
Categories offered. Accessibility, Bike, Driving, Electric Bike, Freight, Pedestrian, Public Space and Public Transit, each with dozens of specific types (for example "Bike Lane Protection," "Unsafe Crossing," "Illegal Parking," "Speeding," "Red Light Running," "Trucks in Residential Area").

Buses: the B65 today and in the draft plan

Today the B65 "runs between Downtown Brooklyn and Crown Heights" over 4.4 miles; the draft plan shortens it to 4.1 miles and would reroute it "to travel on Atlantic Av in both directions between Downtown Brooklyn and Washington Av," discontinuing service on "Dean St and Bergen St west of Washington Av".

On Bergen and Dean today. The MTA's bus speed data lists B65 timepoints on both streets, such as "BERGEN ST/5 AV" and "DEAN ST/5 AV".
Status. A draft, with no effective date.
Why it matters for the boulevard. The reroute frees "one mile on Dean Street and 1.5 miles on Bergen Street for a bike boulevard design that won't put cyclists in conflict with buses".

Average bus speeds, by month

Route-wide average speed for the B65 and the B63, which runs along 5th Avenue across Bergen and Dean (its timepoints in the same data are mostly on 5 Av), calculated as total distance over total travel time from the MTA's segment speed data: B65 2023 to 2024, B65 2025 on, B63 2023 to 2024, B63 2025 on.

Truck routes

Bergen Street is a designated local truck route from 3rd Avenue to 5th Avenue, in BKCB2 and BKCB6, 4 segments on the truck routes map. Dean Street has no truck route segments.

What a local route is. "The Local Truck Route Network is designated for trucks with an origin and destination within a borough." A truck may use a street that is not a truck route only "for the purpose of arriving at his or her destination".
October 4, 2026. None of the 103 truck route changes on DOT's list is on Bergen or Dean.
What is not known. The city has not said whether the boulevard design would change Bergen Street's truck route status (none of the sources above addresses it).

Reading the numbers

Intersections. The 100-foot band around Bergen or Dean takes in every intersection along it: 82.8% of the 2,125 mapped crashes from January 2020 to June 2026 are within 100 feet of an intersection, and those include crashes between vehicles on the cross street. A district-wide rate spreads intersection crashes across all streets, so the corridor's per-mile figure is not on its own evidence that Bergen or Dean is more dangerous than a typical street; the cyclist and pedestrian counts and the per-block ranking are the better comparison.
What a crash record is. Where police placed the crash; "cyclists injured" counts injuries, not who caused the crash. Tap any crash on the map for its record.

311 requests

311 service requests with a mapped point within 100 feet of each street, ; months before 2020 come from the 2010 to 2019 file. A request is one call or app report, not one problem: the same parked car or the same cold building can produce many, and a request is not a confirmed condition. The 100-foot band takes in the buildings on both sides of the street, so building complaints (heat and hot water, noise from a residence) count alongside street complaints.

What they are about

The most common request types on each street in this window (the 14 most common types over the full record are listed; the rest are "Other types").

311 requests by month

By the month the request was made: Bergen and Dean from 2020 on, Bergen and Dean before 2020.

Per street-mile by month: the corridor against Brooklyn

Requests are mapped to an address, so a street's band picks up the buildings along it, while a borough-wide rate spreads every request over every street, including streets with few buildings; denser blocks with more apartments produce more requests of every kind.

The city's other bike boulevards, for comparison

NYC DOT has built four bike boulevards: Berry Street in Williamsburg, 39th Avenue in Sunnyside, Underhill Avenue in Prospect Heights and 31st Avenue in Astoria. Each is mapped with the bike facilities DOT's file shows on it today, and the table puts them next to Bergen and Dean on the same measures for the chosen time window, with crashes and 311 requests counted within 100 feet of each street's centerline.

Berry Street, Broadway to North 12th Street

Williamsburg, Brooklyn · 4,820 ft (0.91 mi) · Opened November 2023

What DOT built. Two-way bike markings, curb extensions with planters and granite blocks, coral paint at intersections, loading zones, and one-way reversals on several blocks so through traffic cannot run the length of the street.
Bike facilities in the DOT file today. Class III: Shared 4,809 ft, measured as feet of facility along the street (a street with lanes in both directions can total more than its length), within the street's centerline limits.
In the time window: loading…

39th Avenue, Barnett Avenue to Woodside Avenue

Sunnyside, Queens · 2,203 ft (0.42 mi) · Implementation began September 2021

What DOT built. An Open Street made permanent with traffic calming, a protected bike lane, new pedestrian crossings, ramps and pedestrian space.
Bike facilities in the DOT file today. Class I: Protected / Shared 1,424 ft, Class III: Shared 779 ft, measured as feet of facility along the street (a street with lanes in both directions can total more than its length), within the street's centerline limits.
In the time window: loading…

Underhill Avenue, Atlantic Avenue to Eastern Parkway

Prospect Heights, Brooklyn · 3,102 ft (0.59 mi) · Proposed 2022, finished 2024 after a pause

What DOT built. Some two-way blocks made one-way for cars with bike lanes in both directions, pinch points and heavy medians on the blocks that stay two-way, and the northernmost block closed at Lowry Triangle.
Bike facilities in the DOT file today. Class III: Shared 2,123 ft, Class I: Protected / Shared 665 ft, measured as feet of facility along the street (a street with lanes in both directions can total more than its length), within the street's centerline limits.
In the time window: loading…

31st Avenue, Vernon Boulevard to Steinway Street

Astoria, Queens · 5,849 ft (1.11 mi) · Design unveiled May 2024, installed 2024

What DOT built. Parking-protected two-way bike path on the north side from Vernon Boulevard to 31st Street and the south side from 35th Street to Steinway Street, a shared street with one-way car traffic between 31st and 35th Streets, painted islands and curb extensions, and directional changes to divert cars.
Bike facilities in the DOT file today. Class I: Protected 4,809 ft, Class II: Conventional / Shared 1,040 ft, measured as feet of facility along the street (a street with lanes in both directions can total more than its length), within the street's centerline limits.
In the time window: loading…

Reading the comparison. The four built boulevards are short (0.4 to 1.1 miles) and each is one street through one neighborhood; Bergen and Dean are 4.4 and 4.7 miles through four community districts. Per-mile rates make them comparable in scale, not in character: a corridor with more intersections and more cross-street traffic collects more crashes in its band. Whether crashes fell after each boulevard opened can be read from its "by month" line for the months before and after the date on its card.

Open questions

Questions the public record does not yet answer, with where each comes from.

Which stretches, and what design? Which blocks get a shared, standard or protected lane, and what else goes with them, waits on the design proposal due later in 2026.
How the notices will be divided. The Admin. Code notice goes to each affected community board and elected official; the city has not said whether the corridor will be noticed as one project or in phases.
Deliveries and curb access. A store owner raised whether delivery trucks could reach the curb if a bike lane runs next to it. Bergen Street is a local truck route from 3rd to 5th Avenue.
Parking. No city document yet says how much curb parking a design would keep or remove.
When the B65 moves. The reroute is a draft with no effective date.

Counting rules

Every count links to the public data or document it comes from. None is a projection of the final design, which the city has not released.

The corridor. Every block of Bergen Street (4.67 miles, 38 blocks) and Dean Street (4.44 miles, 36 blocks) in the NYC street centerline, from Court Street at the west end to East New York Avenue at the east, the same limits the city named.
Within 100 feet. A crash or 311 request counts if its mapped point is within 100 feet of the street's centerline. That reaches across every intersection (an avenue roadbed is 30 to 60 feet wide) and to the building fronts on both sides, without reaching the next parallel street (Bergen and Dean are about 250 feet apart). The city has published no boundary for the project's data, so the band is a convention, not a city definition; each count links to the NYC Open Data query drawn with it, so anyone can redraw it wider or narrower.
One block each. A crash at an intersection is within 100 feet of two blocks; the block-by-block counts give it to the nearer one, so the blocks add up to the corridor. The corridor totals for Bergen and Dean are counted directly with the 100-foot band.
Districts. Community district, Council, Assembly, Senate, Congressional and precinct lines come from the city's published boundary files; a block belongs to the district its midpoint falls in.
