The main tower on the north bank of the Guanyinsi Yangtze River Bridge, the world’s longest-spanned highway cable-stayed bridge constructed by China Railway Construction Bridge Engineering Bureau Group Co., Ltd., was successfully topped out on May 6. The milestone marks a major breakthrough and paves the way for the subsequent construction of the main girders and cable-stay systems. As a key control project of the Wuhan-Songzi Expressway, the Guanyinsi Yangtze River Bridge features a main bridge stretching 1,860 meters, with a central span of 1,160 meters and a 262-meter-tall north tower. The bridge holds five world records, including the longest span for a highway cable-stayed bridge and for a hybrid composite girder cable-stayed bridge. It is also the first in the world to use a hybrid steel-UHPC structure over a 1,000-meter span. Additionally, it features the largest-diameter friction pile group foundation, and the widest and heaviest precast sliding concrete girder segments constructed using the short-line match-casting method.
