And those are just the high-tech, high-profile projects. Even a mundane bridge near a small town saves thousands of people a day of making a detour. This might not sound 'impressive', but imagine a bridge that gets used by just a thousand people a day and that replaces a detour that takes 15 minutes longer. That's a 1000 people * 0.25 hours * 2 times a day = 500 human hours saved per day, or over 180.000 hours saved per year. With a lifespan of 50 years equals that to close to 10 million(!) hours or 4500 'working years' saved. This is an example of just a small bridge near a small town, just imagine the benefit of larger bridges (and other infrastructure projects) near the big cities.
