East China Highway Science and Technology Information Network From June 30 to July 4, 1980, a live cable-stayed bridge seminar was held at the construction site of Jinan Yellow River Bridge in Jinan City, Shandong Province. Jinan Yellow River Bridge is China’s current span of the largest under construction cable-stayed bridge, the maximum diameter of 220 meters in the hole, the main bridge span is 40 +94 +220 +94 +40 meters, the main bridge is 488 meters long. The approach bridge is 24 meters wide and 30 meters pre-tensioned prestressed composite box girder, the total length of the bridge is 2022 meters. Main Bridge Structure: The Twin Towers are inverted Y-shaped double-sided pull-up system of reinforced concrete. There are 11 pairs of inclined cables on each side of the tower. Together with the vertical slings at the fulcrum, a total of 23 cables with a height of 68.4 meters (above the base cap)
