Bridge is an important symbol of the rapid development of human society. Its evolution reflects the evolution of human culture, and bridges in different times represent the cultural heritage of different times. At the same time, in order to adapt to the modern high-speed development of the transportation industry, my country's bridges have evolved from the earliest arch bridges and wooden bridges to today's cross-river bridges and high-speed overpasses. The changes of these bridges all reflect the improvement of my country's industrial level. Learn the architectural knowledge contained in the bridge and the superb skills of the craftsmen, so that the bridge culture can be carried forward and developed.
