A two-lane bridge has collapsed in Pittsburgh, prompting rescuers to rappel nearly 150ft while others formed a human chain to help rescue multiple people from a dangling bus.

The collapse came hours before President Joe Biden was to visit the city to press for his trillion-dollar infrastructure bill, which includes bridge maintenance.
