A school bus carrying about 30 girls lost control on a highway ramp and skidded down an embankment Wednesday in Bonner Springs, Kan.
A bus full of sixth-grade girls overturned on a highway ramp near Kansas City, Mo., on Wednesday, injuring 20 people, authorities told NBC News.
None of the injuries was immediately believed to be serious.
Kansas state Trooper Howard Dickinson told NBC station KSHB of Kansas City that the bus lost control on a curve on the ramp to Kansas Highway 32 and went off the roadway in Bonner Springs, Kan., about 15 miles west of Kansas City across the Missouri line.
The bus — which then slid down an embankment and ended up on its side — was one of two carrying rising freshmen at Pembroke Hill School in Kansas City to a two-night orientation campout at Tall Oaks Campground and Conference Center in Linbrook, Kan.
School officials said 30 girls were on the bus, along with teachers and other adults. Beth Bryant, a spokeswoman for the school, told NBC News that 20 people were transported to hospitals with non-critical injuries.
Overland Park Regional Medical Center, Children's Mercy Hospital in Kansas City and the University of Kansas Hospital in Kansas City didn't immediately report their conditions, but authorities described their injuries as "minor or moderate."
Non-injured students were taken to Bonner Springs High School to be picked up by their parents. The ramp from Kansas Highway 7 to Highway 32 reopened later Wednesday afternoon.
