A man was killed and his stepson injured in a Melville crash that shut down the westbound Long Island Expressway Monday evening in that area, while another accident in Dix Hills about 45 minutes later closed the Northern State Parkway in both directions, authorities said.
As of 12:30 a.m., police said those closures were still in effect and they had no estimate on when the roadways in those areas would be reopened.
The stepson in the LIE accident was driving the Toyota when it crashed into a light pole just east of LIE Exit 49 Pinelawn Road about 7:25 p.m., authorities said.
His stepfather, 83, was killed, while the stepson, 57, a Coram resident, was airlifted to Stony Brook University Hospital, Suffolk police said. The stepson suffered non-life-threatening injuries, police said.
No criminality is suspected at this time, police said.
"We had one car that went off the road, and we had two people ejected from the vehicle," First Assistant Chief Jason Bernfeld of the Melville Fire Department, which handled the injured.
The LIE was shut down between Exit 49 Pinelawn Road and Exit 50, Bagatelle Road in Dix Hills, police said.
On the Northern State Parkway in Dix Hills, an accident on the eastbound side caused at least one vehicle to roll over, state police said.
One woman was airlifted to a hospital while two men were taken to Huntington Hospital by ambulance, said First Assistant Chief Robert Fling, of the Dix Hills Fire Department.
That crash happened shortly before 8:15 p.m., about a quarter-mile west of Deer Park Road, Fling said.
The parkway's eastbound lanes were closed at Exit 41, Wolf Hill Road, and the westbound lanes shut at Exit 42, which is Route 231, state police said.
When firefighters arrived, the woman's vehicle was lying across two eastbound lanes, while the other vehicle had careened into the woods, Steve Silverman, a spokesman for the Dix Hills Fire Department, said shortly after leaving the scene.
"There was debris strewn everywhere," Silverman said.
Fling said the two men suffered minor injuries. He said he had gone up to one of the men, who was lying on the road shoulder.
"He wanted to get up and I told him to stay where he was," Fling said.
State police did not have other details as investigators remained at the scene gathering evidence.
