Bridges, along with many other structural elements, expand (get wider and longer) when heated by the climate or by the Sun. If the bridge decks were fit tightly together, the heat expansion would cause them to buckle up and create a serious hazard to vehicles crossing. The gaps let the bridge expand into them, and nothing buckles.
