What sort of trade-offs do you think engineers make between functionality, safety, and aesthetics when building a real bridge?

When building a real bridge, safety is often the most important factor. Often engineers have to make trade-offs between aesthetics and safety because what is safe does not always look appealing to the eye. In the same way, it is more important that the bridge is functional than aesthetic. Other factors that are often considered are cost, environmental, and consumer satisfaction.
