UPDATE 1.20PM: Katrina Collazo was stopped at a red light when she heard what sounded like small rocks falling on her car.
As she turned around, the Miami Herald reported, the back of her car was crushed, and the car next to her was buried.
A newly installed pedestrian bridge had just collapsed on one of Miami's busiest motorways, crushing eight vehicles, killing up to 10 people and injuring eight others.
A search and rescue operation continued into Friday afternoon (NZT) to try to find more casualties in the rubble.

Collazo escaped death by centimetres.
"Thank God my daughter is alive," Collazo's mother Ada Collazo told the Miami Herald in Spanish. "I thought my granddaughter was in the car, but she wasn't. She's in school."
The pedestrian bridge spanned several lanes of traffic at Florida International University.
Witnesses say cars were waiting for the lights to change when the 950-ton "instant bridge", which was installed in just six hours on Saturday, crumbled and fell on the waiting traffic on the busy, seven-lane 8th Street, which runs from downtown Miami all the way to the Everglades. It was still under construction and not open to pedestrians.
Eight vehicles were crushed, leaving rescue workers racing to free victims from chunks of smashed concrete and snapped metal.

The 53m bridge was designed to connect the sprawling campus of Florida International University with the nearby city of Sweetwater, and to make it safer for students to cross a frenetic roadway.
