Design a bridge and tell us at least what problems should be considered.

First of all, we should consider the safety problem and put forward several schemes suitable for local topographic and geological conditions. For example, round pier or square pier, support form and so on.

Secondly, we should consider the function, such as investigating the local traffic volume, predicting the traffic volume of bridges in the next few years, whether to set up a double deck, whether it is only for vehicles, and so on.

Third, we should consider economy. For example, whether the arch ring of an arch bridge with the same function is reinforced concrete or concrete filled steel tube, which is more convenient to purchase locally?

Fourth, aesthetics should be considered, such as whether the span is a positive single arch or a negative single arch.

I hope I can help you.
