Joe Biden visits Pittsburgh bridge, collapsed hours before infrastructure speech – video

Joe Biden visited the site where one of Pittsburgh's major car bridges collapsed hours before speaking about it in an infrastructure schedule speech in Pennsylvania, on Friday.

At about 7am, the 477ft-long bridge on Forbes Avenue caved in, leaving a mass of concrete rubble and twisted metal as a visual metaphor for America's crumbling infrastructure.

At least 10 people were injured, three taken to hospital, and a bus and several cars left stranded in the wreckage
