What Happened
A crash on the eastbound Long Island Expressway closed two left lanes in Suffolk County on Saturday, July 11, 2026, snarling traffic along one of Long Island’s most heavily traveled corridors. Official records classify the incident as moderate in severity. No specific time, exact mile marker, vehicle descriptions, cause of collision, or details about those involved have been confirmed in the available official record.
The lane closures affected the two leftmost lanes of the eastbound I-495, leaving right-lane travel partially intact but funneling traffic into a reduced roadway at a stretch that already sees among the highest incident volumes on Long Island.
Location & Road Context
The Long Island Expressway (I-495) is Long Island’s primary east-west arterial, running from the Queens–Nassau border through Nassau and across Suffolk County to Riverhead. The I-495 corridor carries enormous daily traffic volumes, particularly on summer weekends when beach and Hamptons-bound traffic intensifies significantly.
The road’s incident history reflects that burden: Long Island Traffic’s database records 1,606 incidents on I-495, with 604 accidents logged across Suffolk County alone. Saturday, July 11, 2026 was an especially active day on the expressway — in addition to this crash, at least three other I-495 crashes and a disabled vehicle were logged the same day. Drivers should also be aware that overnight closures on the LIE and Sunrise Highway for road maintenance were announced for the following week, which may further affect travel planning on this corridor.
