Hongqi

Welcome back to Fall of Nations, where we follow the cracks before the collapse.

The Hongqi Bridge, set in the mountains of western Senchua, a new dam downstream, one of the tallest on the planet, was about to flood the old highway.

So the road had to climb the canyon wall.

And China built this to cross the gorge up there, nearly half a mile long.

And this isn't some anonymous claim floating around online.

This is the Chinese government's own document.

Hongqi was one of five cases spread across five provinces.

The other four killed people.
