A bridge is a structure to cross an obstacle such as water, valley or road without closing another path below. This structure makes it possible to pass obstacles that are difficult or impossible to pass. There are different designs for bridge construction, each of which is used for a specific function and condition. The design of bridges varies with the required performance, ground conditions, materials used, and available capital.
Generally, bridges can be divided into the following based on their application:< /i>
Abareh (water transfer)
Crossing valley or multi-arch (road or rail over a valley or river)
Pedestrian
Highway
Railway
🔸road on railway
🔸transmission pipeline
