What’s The Biggest Land Vehicle Ever Built?

We are concluding the age of miniaturization. Our technological progress has been in making computers smaller and smaller, until they fit in our hands and we pretend they're phones. The time has come to celebrate big things.

So let us start with gigantic land vehicles. Few are larger than the space shuttle's crawler-transporter. It's 131 feet long, 114 wide and over 20 feet tall. It weighs around six million pounds and has a top speed of two miles an hour. That gets halved when the space shuttle rides on board.

Surely mankind has built even larger land vehicles, however. Which ones have we forgotten? Remember, whether it has wheels or tracks or whatever, it's fair game.
