What are the Strengths and weaknesses of major types of bridges?

Major types of bridges, such as beam, arch, and suspension bridges, each have distinct strengths and weaknesses. Beam bridges are simple and cost-effective for short spans but can be limited in load capacity. Arch bridges are strong and aesthetically pleasing, effectively distributing loads, but they require solid abutments and are less suitable for very long spans. Suspension bridges can span great distances and support heavy loads, yet they are complex to design and build, making them more expensive.
