Core Insights - The expansion project of the Jinggang'ao Expressway from the E-Hubei border to Junshan section has successfully opened its core engineering components to traffic, eight months ahead of schedule, marking a significant milestone for the project [1][11]. Group 1: Project Overview - The Jinggang'ao Expressway expansion project is the first of its kind in Hubei, extending 157.79 kilometers with a total investment of 21.01 billion yuan, increasing the road capacity from a dual four-lane to a dual eight-lane configuration [11][13]. - The project spans across Wuhan and Xiaogan cities, aimed at alleviating traffic pressure on the Jinggang'ao Expressway and enhancing the transportation network in the region [13]. Group 2: Key Infrastructure Developments - The newly constructed Hanjiang Grand Bridge, measuring 1,667 meters in length and featuring a main span of 155+450+155 meters, is designed to accommodate eight lanes of southbound traffic [2][8]. - The bridge employs innovative "segment T-beam fully prefabricated construction technology," which breaks down 30-meter T-beams into 6-meter "blocks" for easier transport, representing a new model of green construction [2][6]. - The cross-Handan and Hanyi railway rotating bridge, with a span of 200 meters and a weight equivalent to over 800 medium-sized passenger aircraft, set a new record for multi-point supported rotating cable-stayed bridges in Hubei [6]. Group 3: Regional Impact - The completion of the main line section from Dongxihu Interchange to Wuhan West Interchange, approximately 28 kilometers long, further enhances the regional road network structure [6]. - The project is expected to facilitate smoother transportation and contribute to the high-quality development of the Yangtze River Economic Belt, strengthening Wuhan's role as a comprehensive transportation hub [13].
