A recent aerial photo captures the railway-crossing bridge of Changzhou's Tenglong Avenue expressway after its successful swivel construction in East China's Jiangsu province. As the province's largest-angle swivel bridge, its two 28,000-metric-ton T-shaped girders rotate 91.1 degrees and 75.6 degrees, respectively, to span two key trunk railways. Undertaken by China Railway 24th Bureau, this key control project will optimize the regional transport network and advance the Yangtze River Delta's integrated development.
