Abstract:Tieshan Port District in Beihai City is a rising coastal industrial urban area along the Beibu Gulf. The Binhai Avenue is an east-west coastal thoroughfare that connects Tieshan Port District and the central urban area of Beihai City, which is of great significance for promoting the development and construction of the Tieshan Port Industrial Zone and even the economic development of Beihai City. Taking the construction of the section from No.4 Road to No.5 Road in the Binhai Avenue Phase II Project (Port Section) as the background, a comprehensive evaluation and analysis are carried out on its planning and layout, functional positioning, technical standards, construction conditions, restrictive factors, and node connections. Finally, a more reasonable design scheme combining the short term and long term is proposed. The provided design ideas can be used as a reference for similar high-grade road projects along the coast and crossing railways.
