NYC DOT rendering of planned bus priority and pedestrian safety improvements along Bay Parkway and Cropsey Avenue in Brooklyn, where new bus lanes will serve 35,000 daily riders.
New York City has started work on a major redesign of Bay Parkway and Cropsey Avenue intended to improve bus service and street safety for 35,000 daily riders in Brooklyn. The project will add offset and curbside bus lanes along Bay Parkway from Avenue J to Shore Parkway and Cropsey Avenue from Bay Parkway to 26th Avenue. The improvements will benefit riders of the B6 and B82, two of Brooklyn's busiest bus routes, as well as the X28 and X38. NYC DOT will also install 18 new median islands, pedestrian improvements and dedicated left-turn lanes at 14 intersections. Bus speeds currently fall as low as three miles per hour on portions of Bay Parkway, according to the city. New York City Government
Fast Buses: Mayor Mamdani Breaks Ground on New Bus Lanes and Safety Upgrades on Brooklyn’s Bay Parkway and Cropsey Avenue
Project will speed commutes and improve safety for 35,000 daily riders
Bus speeds are currently as low as 3 miles per hour on Bay Parkway
Mayor Zohran Kwame Mamdani and New York City Department of Transportation (NYC DOT) Commissioner Mike Flynn today announced the start of work on a redesign of Bay Parkway and Cropsey Avenue in Brooklyn that will speed up bus service and improve street safety for 35,000 daily riders along the project corridor as well as the 85,00 daily riders across each route using the corridor.
The project includes a redesign of Bay Parkway from Avenue J to Shore Parkway and Cropsey Avenue from Bay Parkway to 26th Avenue, featuring new offset and curbside bus lanes as well as other safety enhancements. The new bus lanes will improve service for riders on the B6 and B82, the number one and fourth busiest routes in Brooklyn, respectively, as well as the X28 and X38. Bus speeds are currently as low as 3 miles per hour on Bay Parkway.
Both corridors were identified for improvements as part of Next Stop: Fast Buses, Better Service, Mayor Mamdani’s historic partnership with Governor Kathy Hochul and the Metropolitan Transportation Authority (MTA) to make bus service faster and more reliable across 175 bus routes, nearly 75% of all bus routes in the city.
Bay Parkway and Cropsey Avenue are also Vision Zero priority corridors, meaning that they have among the highest rates of pedestrian injuries in Brooklyn. Between 2021 and 2025, four people were killed in traffic crashes on these streets — including two in 2025 — and another 26 were seriously injured.
“We’re redesigning Bay Parkway and Cropsey Avenue with bus lanes and pedestrian improvements because Southern Brooklyn deserves fast buses, reliable service and safer streets.” said Mayor Mamdani. “New Yorkers don’t have time to waste and neither does our administration. We’re getting right to work building a public transit system that New Yorkers deserve.”
“Recently, buses have achieved speeds faster than seen in years, which shows the bus revolution promised by Governor Hochul and Mayor Mamdani is well underway,” said MTA Chair and CEO Janno Lieber. “Next stop: Bay Parkway, where this new bus priority corridor is going to transform the customer experience for 35,000 more daily riders.”
“Bus riders commuting between Midwood, Bensonhurst and Bath Beach deserve a fast and dignified commute, and we’re ready to help improve safety for everyone using the street,” said NYC DOT Commissioner Mike Flynn. “This redesign will increase bus speeds and reliability on two of Brooklyn’s busiest bus routes while better organizing traffic on two of the highest-crash corridors in the borough.”
NYC DOT will add new pedestrian improvements along the routes like upgraded pedestrian ramps as well as 18 new median islands, painted median extensions and painted curb extensions at select intersections. The agency will add new left turn lanes at 14 intersections with high left turn demand and install left turn restrictions at most other intersections on Bay Parkway — addressing a leading cause of fatalities and injuries citywide.
In a NYC DOT study, dedicated left turn lanes correlated with a 15% decrease in left turn pedestrian and cyclist injuries. New left turn restrictions are associated with a 40% decrease in pedestrian and bike injuries.
Offset bus lanes will be installed along the corridor wherever possible. Curbside bus lanes will be used when space is needed to include a dedicated left turn lane. The project will also update curb regulations to support parking on the corridor, including by retiming existing meters, adding new metered parking around the corner from busy blocks and adding Neighborhood Loading Zones and Truck Loading Zones for drop-offs, pick-ups and deliveries.
In 2026, the Mamdani administration has advanced major projects to speed up bus service across all five boroughs, including:
- The Bronx: Fordham Road, 161st Street and Tremont Avenue
- Manhattan: 34th Street, 116th Street, Madison Avenue and Lexington Avenue
- Brooklyn: Marcy Avenue, Flatbush Avenue, Utica Avenue, Church Avenue and Linden Boulevard
- Staten Island: Victory Boulevard
- Queens: Broadway
Together, these projects are part of the administration’s broader effort to make bus service faster, more reliable and safer for millions of New Yorkers who rely on it every day.
