Bridges help us get around but how do they work? In this video we’ll look at all types of bridges and check out the difference between a bridge and a viaduct. There are lots of concepts to learn, like support surface, deck, and span. We’ll find out what happens if a bridge isn’t constructed properly, plus we’ll go on a tour of special bridges around the world.
