Core Viewpoint - The construction of the rapid road network in Yantai is a key project in the city's comprehensive transportation system planning for 2023-2035, aiming to significantly improve urban spatial organization efficiency and achieve efficient travel goals by 2035 [1][24]. Group 1: Project Overview - The rapid road network includes multiple ongoing projects such as the Hongqi Rapid Road East Section, Tashan North Road tunnels, and the Port City West Street interchange, with a focus on completing key nodes by the end of the year [1][24]. - The Port City West Street interchange is a critical node in the "one horizontal and two vertical" rapid road project, designed as the largest and only three-layer interchange in Yantai [4][6]. Group 2: Construction Progress - The Port City West Street interchange features a total length of 1.3 kilometers for the north-south main line and 2.1 kilometers for the east-west main line, with 24-hour construction to ensure completion by the end of September [6][4]. - The construction of the Guanhai Road sunken interchange aims to alleviate traffic congestion, with completion expected by the end of October [11][7]. - The Tashan North Road tunnel project is progressing well, with the eastern section's excavation completed by 88% and the entire project expected to be completed by the end of 2026 [19][20]. Group 3: Future Implications - The rapid road network is expected to relieve congestion, enhance travel quality, and promote cross-regional integration, supporting Yantai's development as an important gateway to Northeast Asia [24][1]. - The comprehensive transportation system planning aims for residents to access rapid roads within 10 minutes, highways within 20 minutes, and external hubs within 30 minutes, significantly improving urban mobility [1][24].

Core Insights - The Yantai Urban Expressway project, undertaken by China Railway Construction Engineering Group, is a key livelihood project for Yantai City, with over 300 workers actively engaged in construction during the May Day holiday [2][3] - The overall cost of the project is approximately 1.131 billion yuan, facing challenges such as significant land acquisition and relocation, as well as high traffic volumes in construction areas [2] - Advanced technologies such as BIM and intelligent traffic monitoring systems are being utilized to optimize management and minimize traffic disruption during construction [2][3] Project Details - The construction of the Gongjiadao Interchange and Hongqi Road main line has entered a full construction phase, with a focus on overcoming traffic management difficulties [2] - The project employs factory prefabrication and precise on-site positioning for large-span steel beam installation, enhancing installation accuracy through laser positioning and dynamic stress monitoring [3] - A modular adjustable support system has been developed for cantilevered beams, utilizing automated tensioning equipment to control prestressing accurately [3] Future Impact - Upon completion, the project will facilitate a three-dimensional connection between major roads, significantly reducing commuting times in urban areas and enhancing the transportation network in the Jiaodong Peninsula [3]
