In june, the “one bridge to the world” micro-commitment public wrote, “the great repair of the yangtze bridge in nanjing — what would the plan be?” the repair and consolidation process is assumed to be similar based on the commonality of the structures of the yangtze bridge in nanjing and the yangtze bridge in kyushu。
In recent days, tenders have been opened for the construction of several segments of the construction of the yangtze bridge road and bridge in nanjing, and the chinese bureau of the bridge has been awarded the “front bridge and tie bridge” section (a) and the “northward bridge” section (b1) as a special company of the chinese bureau of the bridge, which carried out the renovation of the yangtze bridge

The construction of the b1 section of the construction project for the repair and renovation of the yangtze bridge road and bridge in nanjing includes, inter alia, the maintenance of the t liang bridge on the north coast, and the maintenance of the double-curve arch bridge on the north coast。
