Project will speed up buses for 18,000 daily B38 riders and create safer connections for cyclists and pedestrians
Redesign will deliver faster, more reliable commutes and safer streets from Downtown Brooklyn to Bed-Stuy and Bushwick

Mayor Zohran Kwame Mamdani and New York City Department of Transportation (NYC DOT) Commissioner Mike Flynn today announced the start of construction on a redesign of DeKalb and Lafayette avenues in Brooklyn that will speed up bus service for 18,000 daily riders on the B38, create protected bike lanes and make streets safer for everyone who uses them.
The project will redesign DeKalb Avenue from Broadway to Flatbush Avenue and Lafayette Avenue from Ashland Place to Patchen Avenue. Both stretches will feature 2.7 miles of new offset and curbside bus lanes, protected bike lanes and other safety upgrades to improve bus speeds, strengthen connections for cyclists and make streets safer for pedestrians.
The redesigns are 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 the city’s bus network.
“New Yorkers shouldn’t have to choose between getting where they need to go on time and getting there safely. On DeKalb and Lafayette, we’re putting that principle into practice with fast buses, protected bike lanes and safer streets,” said Mayor Mamdani. “New Yorkers deserve a city that respects their time and puts their safety first — and our administration isn’t waiting a moment to build the streets that do just that.”
“Every New Yorker deserves fast, reliable bus service and safer streets. Your zip code shouldn’t determine whether you have access to high-quality, affordable transportation — and that’s what we’re working to deliver on DeKalb and Lafayette avenues,” said NYC DOT Commissioner Mike Flynn. “The redesign of DeKalb and Lafayette will increase bus speeds and improve reliability for bus riders while creating safer routes for all road users and calmer corridors for pedestrians.”
“Under this Governor and this Mayor, Brooklyn’s at the center of a bus revolution,” said MTA Chair and CEO Janno Lieber. “And not a moment too soon for the 18,000 New Yorkers who count on the B38 every day for a safe and speedy commute.”
The project will deliver improvements in neighborhoods where reliable, affordable transportation is essential. Within a quarter-mile of the B38, 80% of residents commute to work by public transit, bike or walk, and a majority of households do not own a vehicle.
Since 2021, crashes on DeKalb and Lafayette avenues have injured 841 people, including 47 who suffered severe injuries. One person has been killed.
In 2026, the Mamdani administration has advanced major projects to speed up bus service and improve street safety across all five boroughs, including:
Together, these projects reflect the administration’s commitment to building a transportation system that works for the millions of New Yorkers who rely on buses, bikes and sidewalks to get around — with faster commutes, more reliable service and safer streets in every borough.
