LOCUST VALLEY - A bus driver was killed and several children were hospitalized after a head-on collision involving a cement truck and school bus in Locust Valley. Police say the accident occurred on Oyster Bay Road at around 3:20 p.m. Investigators say a cement truck hit an overpass, unhinging the cement container it was hauling. The truck lost control and slammed into a minibus that was returning from a summer camp program, according to investigators.

Officials say three 6-year-old boys and a 9-year-old boy were hospitalized. An aide who was riding the bus was also hospitalized with serious injuries, officials say. There is no word yet on the condition of the cement truck driver. The identity of the bus driver who was killed has not yet been released. The Town of Oyster Bay says the children involved in the accident were coming from a town program called Group Activities Program, or GAP. The kids were being taken home from Syosset-Woodbury Park on a Locust Valley School District Bus. A town spokeswoman says the children involved were special needs kids.
