US/Canada have the worst bridges in the world in terms of the condition they are in, followed by Africa.
Let that sink in for a second. Africa has better bridges than the US and Canada do.
In recent times, advanced satellites using radar imaging are giving scientists a powerful new way to watch over the world’s bridges.
A type of radar called Synthetic Aperture Radar can reveal structural displacements as small as a few millimetres and signal early structural problems long before inspectors notice them, say researchers from the University of Houston.
Now, a global analysis of 744 bridges reveals that bridges in North America, which were mostly built in the 1960s, are in the poorest condition, followed by those in Africa.

Satellite images reveal which bridges around the world are at highest risk of collapse
