All lanes of the westbound Long Island Expressway were closed near the Bagatelle Road overpass in Half Hollow Hills Tuesday after a car overturned just before noon, the New York State Department of Transportation reported.
The road was briefly closed so an ambulance and emergency personnel could work the scene. Some lanes were reopened at 12:10 p.m.
It was unclear how many were injured in the crash.
The severity of any potential injuries also was unknown.
Some traffic was diverted off the road at Deer Park Avenue.
