Group 1 - The core point of the article is the successful completion of the load test for the Baihua Lake Bridge, a key project in the Gui'an expansion project of the Hu-Kun National Highway, which lays a solid foundation for the entire line to be opened to traffic [2] - The Baihua Lake Bridge spans 1,086 meters and features a mixed beam single-tower cable-stayed bridge design, making it the largest of its kind in the province [2] - The load test consisted of static and dynamic tests, confirming that the bridge meets design requirements with stable force, smooth line shape, and stable cable force [2] Group 2 - The Gui'an expansion project, led by Guizhou Expressway Group, involves multiple stakeholders and spans 90.722 kilometers, connecting the Guanshanhu District to Puding County [2] - The project is designed to highway standards with a speed limit of 100 kilometers per hour and will become the first smart highway in Guizhou, significantly contributing to regional economic development and rural revitalization [2]

Core Viewpoint - The successful load test of the Baihua Lake Bridge marks a significant milestone for the Gui'an Expansion Project, ensuring the foundation for the entire highway's operation is solid [1][3]. Group 1: Project Overview - The Gui'an Expansion Project, led by Guizhou Highway Group and supported by other stakeholders, spans a total length of 90.722 kilometers, connecting Guiyang City to Anshun City [4]. - The project is designed to meet highway standards with a design speed of 100 kilometers per hour [4]. Group 2: Bridge Specifications - The Baihua Lake Bridge measures 1,086 meters in length and features a hybrid beam single-tower cable-stayed design, making it the largest of its kind in the province [3]. - The main tower of the bridge is a reinforced concrete diamond-shaped spatial tower, standing at a height of 219 meters [3]. Group 3: Load Test Results - The load test consisted of static and dynamic load tests, confirming that the bridge meets design requirements with clear stress under various conditions, smooth line shape, and stable cable forces [3].
