1. Load-bearing capacity: Bridges need to be able to withstand the weight of the traffic that passes over them. The load capacity of the bridge should be calculated to ensure that the structure is strong enough to support the weight of the vehicles and pedestrians that use it.
2. Stability: Bridges should be designed to have a stable foundation which can bear the load safely. The durability of the bridge should be made sure to make it less vulnerable to earthquakes, floods, and other natural disasters.
3. Material selection: The rigidness and strength of the material to be used should match the bridge’s load-bearing requirements. A materials engineer or a geotechnical engineer can help in selecting the correct material for the bridge.
4. Weather conditions: Bridges must be designed to withstand the various weather conditions they will face over time. They must withstand wind, rain, snow, and ice, which can affect the bridge's structural integrity.
5. Proper maintenance: Proper maintenance and regular inspection to identify any structural issues are vital to maintaining the safety and integrity of a bridge. Structural faults must be quickly identified and corrected to avoid further damage.
6. Safety barriers: Barriers are installed on bridges to prevent pedestrians and vehicles from accidentally falling off the bridge.
7. Signage and road markings: Adequate signage must be installed around and on bridges to guide vehicles and pedestrians safely across the bridge. Clear road markings on the bridge’s surface also aid in the safe passage of cars and other vehicles.
