A word to the wise: don't let them bribe you into an alternate lifestyle, living your days out next to a superhighway. The noise alone will kill you. I have cousins in the Philly area who had a four lane highway built on half their property taken via eminent domain, for which the county paid well. But today, it is not possible to sit their new backyard without hearing the incessant traffic beyond the trees they planted and the noise barrier they put up that doesn't work at all. And they were just about to retire when that happened.
The irony is that I am precluded by my planning permission from selling this place in any case - because it is a high amenity area and thus planning permission is restricted to the family of the farmer. So people generally can't get planning permission here - just some planner who wants to build a highway when it is not needed and where it causes maximum damage to the environment. notes from no w here
