I acknowledge the ability of governments to make some of these things an easier task. I don't agree that the task should be made easier at the violation of anyones consent.

The way this worked before eminent domain, is there had to be an agreeable route chosen by those involved before a road was built.

Much of the state I am located in will no longer be able to utilize eminent domain because people are choosing the idea that negotiating   a route is a better idea than ignoring consent.

So in this particular area, (and many others) the market place of ideas is serving subjective value of individual sovereignty over central planning. 

In the end the roads get built by the companies that should do the best in cost, quality and time. This will happen whether the state exists or not, the only difference is the amount of consent that is violated in the process.
