Construction crews will return to Flatbush Avenue later this month to resume work on one of Brooklyn’s most anticipated street redesigns, the city Department of Transportation announced. The project, paused since late last year when winter set in, will pick back up during the last week of April and push through to fall.

The scope is substantial. The redesign covers Flatbush Avenue between Livingston Street and Grand Army Plaza, and it calls for center-running bus lanes, six concrete boarding islands, nearly 29,000 feet of new pedestrian space, eleven dedicated loading zones, and 14 bike parking areas. DOT first broke ground last fall, between Livingston and State streets, before cold weather forced a halt.

The numbers behind this project are hard to ignore. Bus speeds on Flatbush can crawl to four miles per hour during peak times. Four miles per hour. A brisk walk beats that. A 2024 survey by the advocacy group Riders Alliance found that 91 percent of riders experienced delays on the corridor in 2023. The redesign will primarily serve the B41, one of Brooklyn’s most packed routes, along with the B67, B69, B63, B45, and B103. Together, those buses carry 132,000 daily riders.

“Often be as fast to walk as it is to take a bus on Flatbush Avenue, and with over 100,000 riders relying on the bus to get around, that must change,” DOT Commissioner Mike Flynn said. “The new Flatbush Avenue offers a bold blueprint to speed up buses and deliver safer streets.”

For anyone who has stood on Flatbush waiting for a B41 that never seems to come, that framing hits close to home. This stretch of Brooklyn has long been a chokepoint where buses bunch, stall, and frustrate tens of thousands of commuters every single day.

The dedicated lanes will be enforced by bus-mounted cameras operated by the MTA and stationary cameras run by DOT. That enforcement piece matters, because paint alone doesn’t move cars. The city is betting that camera enforcement, combined with the physical separation provided by the concrete boarding islands, will keep private vehicles out of the lanes and let buses actually move.

Mayor Zohran Mamdani framed the project in terms of time, which is probably the right way to think about it. “These center-running bus lanes will give New Yorkers back something precious: time with their families, time at work, time in their communities,” he said. “Long waits and unreliable service are not inevitable, they are the result of political choices. Today, we are choosing a system that puts bus riders first and builds safer streets for everyone.”

The project was first floated by the former Adams administration back in 2022, which means it has taken roughly four years to get from concept to construction. Not fast by any standard. But the redesign is now moving, and the city expects work to run through the summer and into fall.

To limit the disruption to traffic during that stretch, DOT plans to run construction in four phases, rebuilding one side of the street at a time so two-way vehicle traffic can continue on the other half. Drivers are being encouraged to use alternate routes, take transit, or budget extra time. The honest advice here is the second option. If 132,000 people a day already ride those buses through the congestion, more riders in dedicated lanes should, in theory, make those trips faster for everyone.

The Brooklyn Paper first reported on the construction timeline and the details of the phased approach.

Still, the project arrives at a moment when New York is pushing harder on bus infrastructure across the five boroughs. Flatbush Avenue is one of the borough’s most critical corridors, running from Downtown Brooklyn through Prospect Heights, Park Slope, and deeper into Flatbush itself. The communities along that route are largely working-class and transit-dependent. They don’t have the luxury of sitting out a slow bus system.

The redesign won’t fix every problem on the B41. But getting buses out of general traffic, building real boarding zones, and enforcing lane rules with cameras represents a meaningful shift from how the city has historically managed this street.

Construction resumes in roughly three weeks. By fall, Brooklyn’s most important bus corridor should look, and move, very differently.
