Dream of a wooden bridge and it’s a clue that you lack willpower in your waking life. A railroad bridge is a sign of good luck in business. A bridge over a road (viaduct) suggests you’re being too ambitious. See a bridge set in stone or concrete, and any large plans you have will soon be realized. If you see a bridge being built, it means you have an active imagination. If you cross a bridge, a job change is on its way for you.
