There's an old Chinese saying that goes: “If you want to be rich, you must first build roads.”

And, boy, have they built some roads: In the past year, we've seen the world's longest sea bridge, the world's longest gas pipeline and a high-speed railway that's left everyone else in the dust — literally.

The resultant infrastructure push is incredible. A list of 108 super projects is floating around Chinese message boards and we picked out the 45 coolest ones to showcase here.

From highways spanning the continent, to the largest wind power base in the world, to a modern Silk Road that links Europe and India, to new cities in the desert, China is showing what it really means to do big things.
