Only the center lane of the LIE between Exits 37 and 39, Willis Avenue to Glen Cove Road, had been open to traffic from 8:40 a.m. to 9:17 a.m., according to police and the state's Department of Transportation website,

A police spokesman said it was not immediately clear if there were serious injuries. "It doesn't appear that way now," he said.

One vehicle had overturned in the right lane and another had struck a median between Exits 37 and 39, the spokesman said.
