At least four people have been killed and 10 others hurt after a footbridge collapsed near Florida International University in Miami earlier today.
The BBC says rescuers are spending the night searching for victims trapped beneath the buckled structure.
The 862‑tonne, 53 metres bridge fell over an eight‑lane motorway, crushing at least eight vehicles.
The bridge was erected on Sunday in just six hours.
It was built using a method called "accelerated bridge construction" to avoid traffic disruption. A major section of the bridge was assembled on the side of the road and then raised into place.
At least 10 people were treated for injuries, including two who were in "extremely critical condition".
At one point, police ordered TV helicopters to leave the area so rescue teams could hear for any sounds of people calling for help under the wreckage.
