The intersection where Siobhan Lynch died sits along streets already designated as Vision Zero priority corridors by New York City.
BROOKLYN, N.Y. — The death of a pedestrian struck by a city sanitation truck this week is drawing renewed attention to a southern Brooklyn corridor where transportation officials have already documented a history of severe crashes and begun safety upgrades.
Siobhan Lynch, 30, was crossing Bay Parkway at Cropsey Avenue at about 6:35 p.m. Wednesday when a Department of Sanitation truck traveling east on Cropsey Avenue turned right onto Bay Parkway and struck her, police said. Emergency medical workers took her to NYU Langone Hospital-Brooklyn, where she was pronounced dead.
The 41-year-old truck driver remained at the scene and had not been arrested as of Friday. The NYPD Highway District’s Collision Investigation Squad is investigating, and police have not announced a finding about the cause of the crash or whether the driver violated any traffic law.
The intersection is part of a wider area that the New York City Department of Transportation has identified for street-safety work. Bay Parkway and Cropsey Avenue are Vision Zero priority corridors, a designation used for streets where crash patterns have raised particular safety concerns.
City transportation data presented this year showed that 30 people were killed or seriously injured in the Bay Parkway and Cropsey Avenue project area from 2021 through 2025. Two traffic deaths were recorded there in 2025. Transportation officials also reported that turning crashes have been a significant source of pedestrian injuries in the study area.
The city has been advancing changes on both streets as part of a project combining bus improvements with measures intended to make crossings and traffic movements safer. The project area covers about 2.4 miles of Bay Parkway and a roughly six-tenths-mile section of Cropsey Avenue. City officials have said tens of thousands of bus riders travel through the area each day.
Earlier in October, the city announced construction on new bus lanes and street-safety upgrades along the corridors. Officials said at the time that Bay Parkway and Cropsey Avenue had some of the highest rates of pedestrian injuries in Brooklyn and cited four traffic deaths on the two streets from 2021 through 2025.
Lynch’s death occurred shortly after sunset and one day before the city formally launched its annual Dusk and Darkness campaign. The initiative focuses on a seasonal period when evening rush hour increasingly takes place after dark, reducing visibility for drivers and other road users.
The Department of Transportation said Thursday that the hours near sunset become especially dangerous for pedestrians during the fall and that risks increase after daylight saving time ends. Clocks are scheduled to move back one hour Sunday, Nov. 1, bringing sunset an hour earlier by the clock.
The campaign includes public-service messages, outreach to drivers and increased police enforcement during late-afternoon, evening and overnight hours. Police are focusing on violations including speeding, failure to yield to pedestrians, distracted driving and disobeying traffic signals. Traffic enforcement agents are also targeting vehicles that block crosswalks, bike lanes and other areas where visibility can be affected.
City officials said overall traffic deaths and pedestrian fatalities have declined compared with the same period in 2025, placing 2026 among the safer years in the city’s long-term traffic records. Officials nevertheless said the seasonal increase in darkness remains a predictable danger requiring added enforcement and public attention.
The Department of Sanitation said it is assisting the NYPD investigation into Lynch’s death. As of Friday, police had announced no arrest or charges, and investigators had not released a final account of why the truck and Lynch came into contact as the driver made the turn.
