Incident location, Long Island
What Happened
A fatal crash on the Long Island Expressway brought the Wednesday morning commute to a standstill on December 18, 2024, closing all westbound lanes and triggering a major traffic emergency on one of the most heavily traveled highways in New York State. CBS New York was first to report the deadly incident, deploying Chopper 2 — the station’s aerial news helicopter — to fly over the scene and document the scale of the closure for commuters.
According to CBS New York, the crash was confirmed as deadly, with all westbound lanes of the Long Island Expressway shut down as emergency personnel responded to the scene. The closure struck during peak morning travel hours, meaning tens of thousands of commuters making their way toward New York City and western Nassau County were immediately affected. Aerial footage from Chopper 2 showed the magnitude of the road closure from above, underscoring how severely the incident disrupted traffic flow along the westbound corridor.
The specific location of the crash along the LIE — including the town, exit number, or mile marker — had not been published in the initial report from CBS New York. Similarly, the identities, ages, and hometowns of those involved had not been released at the time of first publication, nor had officials confirmed the number of vehicles involved, the type of collision, or any preliminary cause. Charges, if any, had not been announced. This report will be updated as authorities release additional information.
The closure of all westbound lanes during the height of the morning rush meant that delays were likely stretching for several miles in either direction of the crash site. For Long Island commuters who depend on the LIE as a primary artery into Queens and beyond, a full westbound shutdown — even for a limited period — can cascade into delays lasting well over an hour. Drivers were urged by CBS New York to seek alternate routes during the response.
Chopper 2’s presence over the scene reflects the seriousness with which local media treated the incident. CBS New York regularly deploys aerial coverage for major highway incidents on Long Island, and the decision to position the helicopter over the LIE on the morning of December 18 signals that conditions on the ground were significant enough to warrant continuous live aerial monitoring throughout the commute window.
Location & Road Context
The Long Island Expressway — designated Interstate 495 — stretches approximately 70 miles from the Queens–Nassau border to Riverhead in Suffolk County, serving as the primary east–west highway spine of Long Island. It is among the most congested highways in the United States, particularly during morning and evening rush hours when westbound traffic toward New York City builds rapidly. Our database at Long Island Traffic records 795 incidents on I-495 alone, making it one of the most incident-heavy corridors we track. Recent examples include a crash on I-495 on May 25, 2026, a disabled vehicle on I-495 the same day, and an overturned vehicle on I-495 on May 24, 2026 — illustrating the highway’s persistent and recurring safety challenges.
The westbound direction of the LIE is especially critical during the morning commute, as it funnels commuter traffic from Nassau and Suffolk Counties toward the Queens–Midtown Tunnel, the Brooklyn–Queens Expressway, and other connectors. Any significant incident on the westbound lanes during morning hours has an outsized ripple effect across the entire regional transportation network, making the December 18 closure particularly disruptive for Long Island workers.
Broader Impact
Fatal crashes on the Long Island Expressway during peak commute hours don’t just cost lives — they also inflict enormous economic and logistical costs on the region. A full westbound closure during morning rush can affect bus routes, force LIRR riders to scramble, and push thousands of vehicles onto local roads through communities that are not equipped to absorb the overflow. Drivers who found themselves diverted on the morning of December 18 are encouraged to review current and historical incident data for the LIE on our I-495 road page and to report new incidents directly through Long Island Traffic to help keep other commuters informed in real time.
