A 50-year-old bridge collapsed in Pittsburgh early Friday, requiring rescuers to rappel down a ravine and form a human chain to reach a few occupants of a municipal bus that plummeted along with the span. No deaths were reported.
The collapse came hours before US President Joe Biden arrived in the city to promote his $1 trillion infrastructure law, which has earmarked about $1.6 billion for Pennsylvania bridge maintenance.
At least four people required hospital treatment. Five other vehicles were also on the bridge at the time. The cause was being investigated, and crews searched under the debris for additional victims.
