On Sunday morning in the US state of Virginia, cars kept crashing into each other from 7.51am on the Queens Creek Bridge's Interstate 64 westbound lane in York County.
Vehicles also crashed into each other on the eastbound lane as drivers rubbernecked the massive pile-up.
A total of 55 people were taken to hospital and while none were considered in a life-threatening condition, 11 people's injuries were serious, Virginia State Police said.
They added that the crashes were caused by ice and fog.
Footage from the scene showed a seemingly endless line of crumpled cars, many on top of each other.
Rescue teams were having to clamber over vehicles to get to injured people, with lots having to be sawed out of their vehicles.
