Core Points - The Luhuo-Kangding New Bridge Expressway (Luhkang Expressway) has commenced construction with 10 initial points in Ganzi Prefecture, marking a significant step in its development [3] - The total investment for the project is approximately 34.417 billion yuan, with a total length of 186.807 kilometers, aimed at improving transportation efficiency in the region [3] - Once completed, the travel time from Kangding New Bridge to Luhuo County will be reduced to 2 hours, ending the historical lack of expressway access for Daocheng and Luhuo counties [3] Project Details - The expressway will connect key areas, starting from Luhuo County, linking to G4217 Rongchang Expressway, passing through Daocheng County, and intersecting with G0615 Maerkang to Kangding Expressway, ultimately reaching Kangding City [3] - The entire route will feature a dual four-lane highway design with a speed limit of 80 km/h and a construction period of 4 years [3] Environmental and Technical Considerations - The average elevation of the expressway exceeds 3500 meters, with the highest point at 3850 meters, presenting complex geological and ecological challenges [4] - Innovative seismic bridge design methods will be employed to minimize damage risks from earthquakes, alongside the application of new ecological protection technologies to reduce environmental impact during construction [4] - The expressway is a crucial link in the national "Connecting Tibet and Qinghai to Yunnan" initiative, enhancing access to tourism sites such as Tagong Grassland and Bamei Mo Stone Park, thereby promoting the development of a golden tourism corridor between snow-capped mountains and grasslands [4]

Core Insights - Four highway projects in Sichuan province have received project approval and are set to commence construction in the third quarter of this year, with a total length of approximately 458 kilometers and a total investment of about 947 billion yuan [1][4]. Group 1: Project Details - The Luhuo to Kangding Xinduqiao Expressway spans approximately 186 kilometers, with a total investment of about 344 billion yuan, designed for a speed of 80 km/h and featuring a dual four-lane configuration, with a construction period of 4 years [2][3]. - The G8517 Pingshan Xinshi to Yibin Expressway covers about 65 kilometers, with a total investment of approximately 143 billion yuan, also designed for a speed of 80 km/h and a dual four-lane setup, with a construction period of 4 years [2][3]. - The Panzhihua to Yanyuan Expressway has a length of approximately 131 kilometers, with a total investment of around 350 billion yuan, designed for a speed of 80 km/h and a dual four-lane configuration, with a construction period of 6 years [3]. - The Guang'an Ring Expressway West Section is about 76 kilometers long, with an estimated total investment of around 110 billion yuan, designed for a speed of 100 km/h and a dual four-lane setup, with a construction period of 3 years [3]. Group 2: Strategic Importance - These projects are significant for promoting investment and stabilizing growth, contributing to the development of a national comprehensive transportation network, and supporting the construction of the Chengdu-Chongqing economic circle and the implementation of the "Four Modernizations, Urban-Rural Integration, and Five Districts Co-Prosperity" development strategy [1].
