Sin Sin Road Bridge

The design height of the north main tower of the bridge is 263.8 meters, and it will be poured in 45 sections. After completion, it will set a new high record for bridge towers in Nanjing area.

The first connection of the North Shore approach bridge adopts continuous rigid structure with corrugated steel webs with hole span of (50+60+80+100+70) meters, which spans the North shore levees and Shugang Avenue. The main beam is a straight web structure with single box and three chambers. The top width of the main beam is 25.95 meters, the bottom width is 17.95 meters, and the two side flange plates are 4 meters wide.

Project link

Nanjing Xianxin Road river crossing is a major project of Nanjing's urban development during the 14th Five-Year Plan period. It is an important link connecting the main urban area with the state-level Jiangbei New Area and Nanjing Economic and Technological Development Zone, as well as an important part of Nanjing's "high and fast Road system". The main span of the bridge is 1760 meters, and the main line is constructed according to the urban expressway standard, with six lanes in two directions, and the design speed is 80 kilometers per hour.

After the bridge is completed, the fastest travel time from Qixia district to Jiangbei New District will be reduced from 50 minutes to 10 minutes. Construction of bridge is not only beneficial to the Yangtze river delta regional integration of the national strategic development, also will greatly alleviate the pressure of the traffic across the river, to raise the first degree of nanjing, promote the town of ning Yang integration strategy, implementation of nanjing river development and further enhance the Yangtze trunk river ability, improve the regional road network system, has the very vital significance.
