This paper focuses on the requirements of marine long-span bridges for durability and light-weight. It summarizes the research status and development tendency of high-performance steel, high-performance concrete, and fiber-reinforced polymer(FRP),after a thorough investigation on light-weight, high-strength, and durable materials. The application technologies of the aforementioned materials to key zones of bridges are introduced, and the strategic recommendations for the development of light-weight, highstrength, and durable structural materials in marine bridge engineering are proposed. The research results contribute to satisfying the requirements of marine bridge engineering for high performance, long life, and light weight, and overcoming the challenges in durability and span of long-span bridges in marine environment.
