What Happened
A crash on westbound I-495 in Nassau County closed two left lanes on Thursday, July 23, 2026, according to incident data logged in the Long Island Traffic database. The collision was classified as moderate in severity. No additional details — including the precise mile marker, cross-street, time of day, number of vehicles involved, or injuries — have been confirmed in the available incident record at this time.
The lane closures affected westbound traffic on the Long Island Expressway as it moves through Nassau County, one of the most heavily traveled segments of the corridor. With two left lanes blocked, drivers heading toward Queens and New York City would have faced significant queuing during the closure period.
