Property abutting highway between Playa Dorada and Airport

My husband and I are considering purchasing a property that abuts the highway between Playa Dorada and the airport, more specifically, near Cangrejo. We love the property and it has great potential for both building a home or the potential to have a business because of it's location to the highway. However, we are just wondering what would happen if they were ever to widen the highway? Can the government expropriate land? We would obviously not want to build a house, only to have part of our land taken over to widen the roadway. Well I am sure they can since seem to be able to force residents to move if they want the land, i.e. the Boca Nueva residents who lived at Playa Bergantine were forced to move to Montellano (although new housing was provided).

Anyway, I just thought I would check if anyone might have some insight, suggestions, warning, etc. with respect to buying property that abuts the main highway.

Thank you both for your helpful responses. I figured as much about expropriation. I guess we are just weighing the risks involved v. the cost of this piece of land, which is less than $15,000. It could prove to be quite valuable if the Playa Bergantine area becomes developed in the next 10 years and we could open a business along the highway? We likely won't be building on it for 10 years or so, but I would hate to hold onto it, only to have the government make plans to widen the highway and then we lose our land and have to look elsewhere to build.
