New York City has begun construction on a major bus-priority project in southern Brooklyn, targeting corridors where buses travel as slowly as 3 mph and thousands of daily passengers contend with traffic congestion.
Mayor Zohran Mamdani and New York City Department of Transportation (NYC DOT) Commissioner Mike Flynn announced the start of work Oct. 6 on Bay Parkway and Cropsey Avenue. The redesign will introduce dedicated bus lanes, modify intersections, and improve pedestrian infrastructure along two heavily traveled streets.
The improvements will directly affect approximately 35,000 daily riders along the project corridor, with roughly 85,000 riders using the bus routes that travel through it.
The project is part of New York City's broader Next Stop: Fast Buses, Better Service initiative, which aims to improve bus speeds and reliability across 175 routes citywide.
New bus lanes target chronic delays
The redesign covers Bay Parkway between Avenue J and Shore Parkway and Cropsey Avenue between Bay Parkway and 26th Avenue.
The project will benefit four bus routes: the B6, B82, X28, and X38. The B6 and B82 are particularly significant, ranking as Brooklyn's busiest and fourth-busiest bus routes, respectively.
NYC DOT plans to install a combination of offset and curbside bus lanes, with the configuration varying according to intersection requirements.
Offset lanes, positioned away from the curb, will be used wherever possible. Curbside bus lanes will be installed where additional street space is needed for dedicated left-turn lanes.
The approach is intended to reduce interference from general traffic while accommodating turning vehicles, deliveries, and other curbside activity. Those competing street uses are a central challenge for agencies seeking to improve bus performance in established urban corridors.
Safety improvements accompany transit upgrades
The project also addresses pedestrian safety along two streets designated as Vision Zero priority corridors because of their elevated crash rates.
Between 2021 and 2025, traffic crashes on Bay Parkway and Cropsey Avenue killed four people and seriously injured another 26, according to the city.
NYC DOT will install 18 new median islands, along with painted median extensions, curb extensions, and upgraded pedestrian ramps at selected intersections.
Intersection changes are another major component. The agency plans to add dedicated left-turn lanes at 14 intersections with significant turning demand while restricting left turns at most other intersections along Bay Parkway.
The city cites previous NYC DOT research associating dedicated left-turn lanes with a 15% reduction in pedestrian and cyclist injuries involving left-turning vehicles. Left-turn restrictions have been associated with a 40% reduction in pedestrian and bicycle injuries.
The redesign will also modify parking and loading arrangements, including adjustments to metered parking and the creation of neighborhood and truck loading zones. These changes are intended to accommodate commercial activity while reducing conflicts with bus operations.
Part of a larger bus-priority investment
The Brooklyn project advances a broader effort by the Mamdani administration, New York State, and the Metropolitan Transportation Authority to address slow bus service across the five boroughs.
Announced in July, Next Stop: Fast Buses, Better Service identifies 50 priority corridors for improvements and includes plans for five next-generation rapid bus routes.
The city has committed $254 million in operating funding and $628 million in capital funding over five fiscal years to support the initiative.
The program targets a 20% improvement in bus speeds along priority corridors, with potential travel-time savings of up to six minutes per trip. Planned improvements include dedicated bus lanes, transit signal priority, expanded automated bus-lane enforcement, passenger amenities, and fleet modernization.
NYC DOT has also advanced bus-priority projects on Fordham Road in the Bronx, 116th Street in Manhattan, and Madison and Lexington avenues, among other corridors.
The Bay Parkway and Cropsey Avenue project adds another corridor to that implementation program, with construction now underway.
A test of street-level transit improvements
For transit agencies, the Brooklyn project illustrates how bus-priority programs require coordination between transportation planning, roadway engineering, traffic operations, and pedestrian safety.
The improvements are being introduced on existing streets, where agencies must balance faster bus movements with vehicle access, turning restrictions, parking, and commercial deliveries.
Their operational value will ultimately depend on measurable improvements in bus travel times and reliability after construction.
New York City has established ambitious citywide speed targets, but the Oct. 6 announcement does not specify a projected travel-time reduction or completion date for the Bay Parkway and Cropsey Avenue project.
That leaves an important performance question for the corridor: How much improvement can dedicated lanes and targeted intersection changes deliver on streets where buses currently travel as slowly as 3 mph?
As construction proceeds, the project offers another example of how transit agencies and municipal transportation departments are using existing roadway infrastructure to improve bus service without waiting for major fleet or system expansions.
