At least 18 hurt in Wisconsin school bus wreck
Two people have been air-lifted to hospital, and the severity of their injuries is unknown.
Two elementary-age students were severely hurt and were flown to Children's Hospital of Wisconsin in Milwaukee, said Lt. Paul Falduto, a sheriff's spokesman.
Reports varied between 18 and 20 injured people, he said.
"The other ones are anything from broken bones to scrapes and bruises," he said.
The collision occurred about 3:45 p.m. on the eastbound side of Wisconsin Highway 50 near County Trunk Highway B as the bus was dropping off children. The Wisconsin Department of Transportation announced on its Web site that all lanes of traffic in both directions from County Trunk Highway W to State Highway 75/83 were closed as of 4:30 p.m.
"The semi came over the hill and struck the bus right in the middle of the rear end," said Kenosha County Sheriff David Beth.
The sheriff said deputies accompanied the truck driver to the hospital as they investigated.
A woman who answered the phone at Wheatland Center School in Burlington, a prekindergarten through 8th grade school where the children are thought to be students, said the school would not comment until all parents were informed of the collision.
