Would you feel a little nervous about driving across this bridge?
Interestingly, the Millau Viaduct is not straight. Why?
It's because a straight road could induce a floating sensation as you drive across it. (wheee). So, a slight curve remedies that feeling. The curve is 20km in range. Moreover, the road has a slight incline of 3% to improve the visibility & reassure the driver.
