Can Michigan build roads that lasts longer?

The Michigan Department of Transportation is trying something a little new this year when reconstructing our roads. Genesse and Kent counties will be apart of this years road experiment . Most roads in Michigan were built to last twenty years, at most. The new material supposedly can last a maximum of fifty years. A problem is the cost, it’s estimated that the fifty year roads could cost 50% up to 100% more then what we have now. The Michigan Department of Transportation does not even know for sure if this new system will work in urban areas because of wiring and gas lines under the road. The main difference in the fifty year road is there is 36 inches of sand and gravel rather than the normal 24 inches. So digging deeper and the cost could play a major effect on if we all get the privilege of these new and improved roads.
