Location & Road Context
NY 135, the Seaford-Oyster Bay Expressway, runs north-south through central Nassau County, connecting the Southern State Parkway at its southern terminus to the Long Island Expressway (I-495) and Northern State Parkway at its northern end. The corridor carries heavy commuter volume, particularly during morning and evening rush hours.
According to Long Island Traffic’s incident registry, Wednesday’s crash is the 8th recorded incident on NY 135 in the past 30 days and the 16th on the corridor in 2026. A fatal crash on this corridor occurred on July 2, 2026.

Long Island Traffic’s database holds 1,313 recorded accidents in Nassau County in total.
Broader Impact
The two-left-lane closure on a high-volume northbound expressway mid-week typically backs traffic past adjacent interchanges. Drivers approaching the closure from the Southern State Parkway connection should allow extra travel time or consider alternate routes on parallel corridors until Nassau County Police reopen the affected lanes.
