What are the motifs in Roadwork by Stephen King?

Eminent domain statutes basically state that the government can expropriate any property they deem necessary as long as they give adequate notice and pay fair market value. While it should be understood that if construction of this kind is absolutely necessary, the government should have the right to insist and assert themselves, it should also be reasonable. If the construction proposed is unnecessary, as it was in this case, there should be a venue where the average homeowner can have some say. In the case of Bart and Mary Dawes, the eminent domain law cost them their home and Bart's place of employment he'd had for years. Each had special emotional significance to Bart.
