Nancy, aged 70, has a vacant plot adjacent to her house that she intends to bequeath to her grandson Roy upon her death. However, an important railroad project is being undertaken nearby and the local authorities have informed Nancy that the new railroad will cover her vacant lot. They have also promised her fair compensation in return. Can the government take her property?

Yes, the government can take her property.

Explanation:

The government can take Nancy's property because it has eminent domain over the property. In other words, it means that the government can take private property and make it a public giving the owner compensation for the land. Besides, there has to be a public purpose for the eminent domain over the plot; which, could be the construction of roads, railroads, or public buildings.
