Answer 1

What you don’t see in most suspension bridges is where these relatively small cables end up.

The cables transmit most of the forces of the bridge weight and vehicle weight along their lengths and these cables end up buried in tons and tons and more tons of concrete which is connected to the bedrock with very deep steel rods.

So the bits you can see are small, but the bits you can’t see are **massive**.
