Core Viewpoint - The construction of the 108 New Line Expressway is progressing rapidly, aiming to enhance transportation in the western mountainous region of Beijing and improve disaster resilience and economic development in the area [2][8]. Group 1: Project Overview - The 108 New Line Expressway spans approximately 60 kilometers, connecting G5 Jingkun Expressway and traversing various national parks and scenic areas, ultimately reaching Hebei [2]. - The project features a challenging terrain with 41 bridges, 20 tunnels, and 9 interchanges, resulting in a bridge-tunnel ratio of 88% [2][8]. - The construction is being managed by Shoufa Group's Shoufa Construction Company, with full-scale operations currently underway [2]. Group 2: Construction Challenges - The construction site is characterized by steep terrain and complex geological conditions, necessitating the use of anti-slip chains on construction vehicles [5]. - The West Dadi Bridge is highlighted as a key engineering challenge, with significant depth and height requirements for its foundation [8]. - The project includes multiple crossings over rivers and railways, emphasizing the engineering difficulties faced during construction [7][8]. Group 3: Economic and Social Impact - The expressway is designed to improve connectivity for local towns, facilitating travel for residents and promoting local economic growth [7][8]. - Upon completion, the expressway is expected to alleviate congestion in the Beijing western corridor and enhance the rapid accessibility of tourism destinations in the region [8]. - The project is part of the national comprehensive transportation network plan, contributing to the broader connectivity between the Beijing-Tianjin-Hebei region and the Chengdu-Chongqing area [8].

Core Viewpoint - The construction of the 108 New Line Expressway, a key transportation route in the western mountainous area of Beijing, is being led by the Shoufa Group, with the 7th section (Fozizhuang section) undertaken by China Railway 14th Bureau [2][4][6][8][11] Group 1 - The total length of the 7th section is 4.3 kilometers, with a bridge-tunnel ratio exceeding 70% [2][4][6][8][11] - During the May Day holiday, over 600 workers worked day and night, utilizing 200 pieces of equipment to advance the construction [2][4][6][8][11] - The project focuses on overcoming challenging engineering tasks, including the construction of the Heilongguan tunnel group [2][4][6][8][11]

Group 1 - The construction of the 108 New Line Expressway is progressing rapidly, with significant developments such as the initial formation of tunnel entrances and the establishment of bridge piers [1] - During the "May Day" holiday, over 400 workers continued construction efforts, with project manager Kong Yongming overseeing daily plans and safety checks [1] - The project includes key structures like the Dongzhuangzi Bridge and the Jiangjun Tuo Interchange, which are crucial for connecting to National Highway 108 Phase III [1] Group 2 - The only service area along the route, Fozizhuang Service Area, is being constructed using tunnel spoil to fill the rugged terrain, with a total area of 2.4 hectares [2] - The 108 New Line Expressway spans approximately 60 kilometers, with a bridge-tunnel ratio of about 88%, indicating a complex construction environment [2] - The project is expected to enhance disaster resilience and transportation integration in the western mountainous region, contributing to the economic and social development of the area [2]
