Truss bridges often use equilateral and isosceles triangles to distribute weight because the equal angles allow forces to spread evenly across the bridge. Triangles are one of the best shapes for distributing weight because they take force from a single point and distribute it across a wide base.
What makes bridges so strong?
Trusses help a bridge spread out the weight that it has to carry. But not all bridges are made of trusses. If a bridge has to cross a really wide body of water, it might be too difficult or expensive to build a truss bridge. So engineers designed another kind of bridge called a suspension bridge.

How long can a bridge survive?
On average, most well-built bridges today last up to 80 years, with deterioration occurring on the main body of the bridge rather than its serviceable components. What is this? One of the prime determinants of bridge longevity is the material used to construct the bridge.
