What Happened
A moderate-severity crash on eastbound I-495 shut down three right lanes on Sunday, July 12, 2026, snarling traffic along a heavily traveled stretch of the Long Island Expressway in Nassau County. The lane closures were reported through official incident tracking, with the right-lane blockage creating a significant pinch point for eastbound motorists during what had already been an active day for crashes on the corridor.
No names, vehicle descriptions, or specific times have been released by officials for this particular incident. The three-lane closure on the right side of the roadway suggests the crash involved the shoulder and travel lanes nearest the right edge of the highway, a configuration common in rear-end or merge-related collisions on busy expressway segments. Police have not yet confirmed additional details on the number of vehicles involved or whether injuries required medical transport.
Location & Road Context
I-495, the Long Island Expressway, is one of the busiest and most crash-prone highways on Long Island. Long Island Traffic’s database has recorded 1,611 incidents on this road, with at least five separate incidents logged on July 11–12 alone — including two additional minor crashes and a construction closure on July 12, and a moderate crash the day prior on July 11. Nassau County’s stretch of the LIE carries heavy commuter and recreational traffic, particularly on summer weekends when beach and event traffic compounds normal volume. Nassau County overall accounts for 816 recorded accidents in the Long Island Traffic database.
Broader Impact
The sheer volume of I-495 activity on this single weekend underscores how quickly conditions can cascade on the expressway. Sunday’s three-lane closure came on the same day as at least two other crashes on the same road — and just one day after a critical wrong-way crash that killed two people on I-95 in Nassau County and a separate moderate crash on I-495. Drivers on eastbound I-495 should expect that multi-lane closures in Nassau County — especially on summer Sundays — can back up traffic well west of the incident scene.
