* Vulnerability to wind: Suspension bridges are susceptible to wind-induced vibrations, which can cause the bridge to sway or even collapse. This is a particular concern for long-span suspension bridges, which are more vulnerable to wind forces. To mitigate this risk, suspension bridges are often equipped with aerodynamic fairings or other devices to reduce wind resistance.
* Complex maintenance: Suspension bridges require regular maintenance and inspection to ensure their safety and performance. This can be a time-consuming and costly process, as it often involves specialized equipment and expertise. For example, the main cables of a suspension bridge must be regularly inspected for corrosion, wear, and damage.
* Limited capacity: Suspension bridges have a limited capacity for carrying vehicles and pedestrians, compared to other types of bridges. This is due to the fact that the weight of the bridge itself, along with the live load (vehicles and pedestrians), can put a strain on the cables and other structural components. To increase capacity, suspension bridges can be designed with multiple decks or with wider lanes, but this can add to the cost and complexity of the bridge.
* Aesthetic impact: Suspension bridges can have a significant aesthetic impact on their surroundings, both positive and negative. Some people find suspension bridges to be visually appealing and iconic landmarks, while others may view them as intrusive or disruptive to the natural environment. The design and appearance of a suspension bridge should be carefully considered to ensure that it is compatible with its surroundings.
