It's actually an achievement in its own right, it wasn't a 8 lane road bridge, it was a fucking walkway, maybe 10 meters long. If they laid down a pair of tree trunks and hammered a few planks on it, it would last hundreds of years.
"Any idiot can build a bridge that never collapses, it takes an engineer to build one that just barely doesn't collapse" is the common form of that saying.

In engineering, they say the trick is not building a bridge that stays up, but one that barely avoids collapsing.

It's all about efficiency.
