To see a highway in your dream represents your sense of direction and your life’s path. Consider the conditions of the highway which will reveal how much you feel in charge of your life. A smooth, straight highway signifies inner peace, while a winding, bumpy road reflects emotional distress/disharmony.
To see an elevated highway in your dream implies that you are taking the higher road in some situation. Alternatively, the dream means that you believe your way of doing things is more superior.
