What Happened
A crash on southbound NY 135 in Nassau County prompted the closure of two right lanes on Monday, July 6, 2026, according to incident data recorded for Long Island Traffic. The collision was classified as minor in severity, though authorities have not yet released details regarding the number of vehicles involved, the cause of the crash, or whether any occupants sustained injuries requiring medical attention.
The lane impact — specifically the two rightmost lanes of the southbound roadway — created a significant chokepoint for drivers navigating one of Nassau County’s busiest north-south corridors during what is typically a high-traffic travel period. July 4th holiday weekend travel often extends into the following Monday, and conditions on the expressway on the afternoon and evening of July 6 are likely to have reflected elevated volume, though weather and precise time of day for this incident have not been confirmed by officials.
Nassau County police have not yet issued a formal press release identifying any parties involved, and details including vehicle types, direction of impact, speed, and contributing factors remain limited based on available official records. Long Island Traffic will update this report as additional information is released by the Nassau County Police Department or other authoritative agencies.
It is worth noting that July 6, 2026 was a notably active day for incidents across Nassau County’s road network. In addition to this crash, a separate crash and a downed tree were also reported on NY 135 on the same date, suggesting that road conditions or weather may have been factors in multiple events. Police have not yet confirmed any connection between these incidents.
