What are 2 things engineers must consider before building a bridge?

There are many factors that an engineer must consider as a part of designing a bridge. The primary factor is the use of the bridge, covering loads size, and impacting the types of bridges that can be built. The second most important factor is the constraints of the location, this includes span requirements and features of the environment that must be considered. In combination with both of these, the available funds for construction and future upkeep can dictate limits, or even result in the ultimate finding that a practical bridge cannot be built. The problems in construction and aesthetics are also major factors that will dictate the final design, and in some cases, this has resulted in new construciton methods being designed as well.
