The construction infographic from Rock and Dirt magazine has some fascinating info. Did you know the Great Wall of China is over 31,000 miles long and took over 2,000 years to build? Or that over 30,000 workers died in building the Panama Canal?

I also learned that the most expensive construction project in the world (in recent history) was the US Interstate highway system, coming in at $425B US. The highway consists of over 47,000 miles and 25% of all vehicle miles in the US are on the Interstate highway system.

So take a couple of minutes and follow this link, to see the fun and informative construction infographic.
