The advancement of engineering materials is the driving force behind the development of engineering structures. The history of bridge construction for thousands of years is also a history of bridge construction materials. The invention and promotion of new materials often greatly promote the development of bridge engineering. Historically, concrete and steel are good examples. Since the 20th century, these two "new" materials have gradually replaced ancient bridge construction materials such as wood, stone, and brick in the world, enabling human bridge construction to achieve unprecedented great development.
