Southbound Route 111 in Hauppauge was closed for about two hours Tuesday afternoon at the Long Island Expressway while police investigated an incident in which a woman was seen running up to the highway's overpass and ended up injured on Route 111 below, said Suffolk County police and the Suffolk Sheriff's department.
The route was reopened about 4:30 p.m., authorities said.
The woman was taken to a hospital. The extent of her injuries was not immediately known, but she reportedly was talking at the hospital, said sheriff's Chief Deputy Kerry Kneitel.
He said he had no information on how the woman got from the overpass down to Route 111, and that Suffolk police were investigating.
The woman had been driving on the westbound expressway, when she pulled off onto the shoulder of the road, got out of the car and was clipped by the mirror of a slow-moving vehicle, he said. She got back in her car, started driving, and tried to get out of her still-moving vehicle, he added.
After veering off the road and into a tree, she got out of her car and witnesses reported seeing her run up to the overpass, he said. She then wound up on Route 111, said Kneitel, who said the incident was reported to the sheriff's office at 2:09 p.m.
