Abstract: The Chinese Eastern Railway bridges-and-

tunnels heritage is an important part of Chinese railway heritage system. This article puts it under the background of the emergence and development of railway bridges and tunnels in the world. Through literature review, case study, comparative and inductive analysis, the article approaches such heritage regarding its characteristics of riveting technology, structural materials and pier construction of large-span steel bridges under severe cold environment, the realisation of large-scale multi-span stone railway bridges and the application of reinforced concrete in stone bridges, as well as the high-precision survey technology and the construction of long-distance tunnels by digging from both ends. It further summarises the advancements of Chinese Eastern Railway bridges and tunnels in material application, structural innovation, construction technology and other aspects through comparisons with domestic and foreign bridges and tunnels in the same period, leading to the significance and values of Chinese Eastern Railway bridges-and-tunnels heritage in science and technology, culture, history, art and society. The article intends to contribute to a systematic, scientific, integrated protection of Chinese Eastern Railway heritage and its future application for World Heritage.
