A pedestrian bridge has collapsed at Florida International University with potential loss of life, authorities say.
Images of the buckled structure at the college in Miami were shared across social media on Thursday afternoon.
The 950-ton span only went up on Saturday, CBS Miami reports.
The Miami Herald reported that an unknown number of people were trapped underneath the bridge, which was built over a motorway.
Miami-Dade County Emergency Management confirmed the collapse and urged locals to avoid the area.
It is unclear how many people have been injured on or beneath the bridge, but images from a local reporter show cars trapped beneath the fallen structure.
The paper said that the bridge has long been requested for by people at the university so they could avoid the perilous road.
In August 2017, a student was hit and killed by cars while crossing.
