It happened around 8:00 Friday morning at the intersection of West Tomlin Station Road and Wolfert Station Road in East Greenwich Township.
Police say the girl, a fourth grade student at Samuel Mickle Elementary, was waiting for the school bus with her father inside a mini van. When she saw the school bus approaching, she exited the van and ran into the street.
At that point, police said, she ran into the side of a construction van traveling east on West Tomlin Station Road.
The girl was transported to Cooper Hospital in critical condition.
She suffered a leg and head injury.
Police tell Action News speed does not seem to be a factor in the accident and no charges will be filed.
However, the investigation into this case continues.
