Some people may think that a road has no business even being considered a manmade wonder much less showing up on this list. The reason why I-70 belongs on this list is that it is one of the greatest feats of human engineering ever. This roadway was one of the single largest projects ever taken on by the United States Government and to this day stands to a testament to the power and strength of our nation. It may seem like a simple highway but its construction was far from easy.
