Sure, they didn't have to worry about property rights, environmental impact studies, etc. They just did it. We built the first interstate highways pretty quickly too, and part of why is we just plotted a line and set the bulldozers to work. Nobody worried about habitat destruction, erosion, endangered species, etc.
