Ask Autoblog: How are Michigan roads made?

From Autoblog:

The process of constructing roadways in a Michigan is a long and arduous one that takes many millions of dollars, countless workers standing around and at least five seasons to finish. Roadways here on the home turf of the American auto industry are a unique breed. Even though Windsor, Ontario is just across the river from Detroit and has exactly the same climatic conditions, its roads are completely different from those in Michigan. That becomes immediately apparent as your roll off the Ambassador Bridge. Autoblog strives to keep you informed about all things even vaguely related to cars. Therefore, we present our step-by-step guide to the creation of a Michigan road. The process typically starts in the spring as soon as the salt has been rinsed away. Before the first crocuses pop out of the dirt, the crews start setting out signs and orange barrels along the edges of the most heavily traveled thoroughfares. There they typically sit for anywhere from one to four weeks before the crews return to start closing off lanes of traffic. After another interval of random length, the heavy equipment begins to arrive and the process of tearing apart the existing pavement begins. Just to make sure that no one accidentally misses out on the fun, the same scenario is usually repeated along several parallel paths that might serve as alternate routes between any two major points that people commute. Learn about the rest of the process after the jump.
