Why are trusses are so useful in structures?

With trusses you can obtain high strength of the bridge using rather thin and simple (i.e. cheap) elements. A drawback is that the required height of the side of the bridge rises with the span of the bridge, so trusses become less effective for larger spans compared to the cable bridges. Railway bridges have to sustain higher load than road bridges (trains are heavier), so trusses are an efficient design to increase strength.
