A speeding car struck the end of a median wall Friday morning, seriously injuring an infant and shutting down a Jane Byrne Interchange ramp for five hours.
The driver of the car was cited for failure to secure the child in a car seat, state police said.
Four adults were also injured in the two-car crash, which happened about 7 a.m. on the ramp from northbound Dan Ryan to the westbound Eisenhower, according to Illinois State Police.
One car occupied by four people in their 20s and a 6-month-old boy tried to change lanes and struck an end-cap barrier of a median wall, state police said. The car spun out and was struck by another vehicle.
A citizen attempted to drive the infant to the hospital themselves, but then pulled over and awaited an ambulance, which took the infant to Stroger Hospital, according to Chicago fire spokesman Larry Merritt.
Merritt said four other adults, three male and one female, were taken in either fair or serious condition to Stroger and Mount Sinai Hospitals. State police said they were expected to survive their injuries.
State police said the person in the other vehicle was uninjured.
The driver of the car that spun out was cited for failure to secure a child under 8 years old, driving too fast for conditions, improper lane usage and damage to a highway structure.
