Advantages and Disadvantages of Suspension Bridges

Advantages and Disadvantages of Suspension Bridges

Suspension bridges are the bridges that hang on two towers on either ends with the help of ropes, strings or cables. There are a lot of suspension bridges already built around the world. You can see many suspension bridges in India too.

Here we are going to discuss about the advantages and disadvantages of the suspension bridges.


  1. Long Distance – The key advantage of the suspension bridges is that they can be built up to very long distances without any problem. Among all other types of bridges suspension bridges are the longest bridges that can be built. An example of this can be seen in Mumbai, the Bandra- Worli Sea Link.
  • Inexpensive to Build – Another key factor of suspension bridges is that they are very budget friendly and inexpensive to build in comparison to other kinds of bridges. The material used in building suspension bridges are also cheaper in comparison to the cost of materials used in building traditional bridges.
  • Easy to Maintain – Since the material used in suspension bridges is less costly as compared to the traditional bridges, the cost of maintaining these bridges is also comparatively less. Also, if any of the segments of the bridge faces any issues, the individual part can be easily changed or repaired without affecting the whole bridge. Since most of the bridge is composed of cables, it is very easy to repair and maintain the bridge and its structure.
  • Attractive Looks – It is no hidden fact that some of the most attractive and eye-pleasing bridges across the world are suspension bridges. With the attractive design and picturesque views these bridges are very pleasing to the eyes.


  • Vulnerable to Speedy Winds – Very high speed winds flowing in full stream can affect the functioning of these bridges. Since these bridges are designed to counter natural disasters like Earthquake, they are not fixed at one place. Hence during the time of speedy winds, driving over these unstable bridges can be harmful.
  • Limited Loads – These bridges are very light weight since the use of materials like concrete and cement is less as compared to the traditional bridges. Hence, these bridges can only bear limited amount of load. It can be harmful to pass heavy vehicles like Dumpers, Trucks and Tanks over these bridges.

Time taking – This is the real concern. The main motive behind construction of such bridges is to build a sustainable structure that can last for a long time. The only disadvantage is that the construction process of building such bridges is a time taken process.
