Question: Disadvantages of a beam and column bridge?

A beam and column bridge is a type of bridge that consists of horizontal beams supported by vertical columns or piers at each end. This design is simple, easy to construct, and cost-effective for short to medium spans. However, it also has some disadvantages, such as:

- It has a limited span and cannot cross large gaps or waterways without intermediate supports.

- It may not be able to withstand heavy loads or high-speed traffic due to the bending stress on the beams.

- It may have height restrictions for the vehicles that can pass under it, depending on the clearance between the beams and the ground.

- It may not be aesthetically pleasing or offer a variety of design options compared to other types of bridges.
