Our infrastructure is vast, and not just because of our landmass. Everything that goes into our infrastructure benefits our economy by improving the conditions in which product and citizens travel through our large nation. 

Transportation is a huge part of our infrastructure. Planes, trains, and automobiles are our main transportation modes. We need to take care of the paths they use to get from place to place. Our economy depends on our transportation infrastructure. 

Building is part of our infrastructure. This includes maintenence and care of our buildings. 

Power is part of our infrastructure. We have many power sources available to us which include but are not limited to nuclear, solar, and wind. Let's use them. 

Our infrastructure needs some major oversight to ensure projects are completed and maintained.
