On July 13, with the last 40-meter T-beam falling steadily, the Qibiao Tongzi River Bridge of Guizhou Jinrentong Expressway, which China Railway Guangzhou Engineering Group constructed, was completed. The bridge is the first large-span suspension bridge with high and low towers designed without pile foundation in the world, and it is also the largest span and the most challenging construction control project of Jinrentong Expressway.
