2nd Nanjing Yangtze Bridge

Aperçu

Project description

With a population of six million people, Nanjing is one of the largest cities in China. Most inhabitants live on the south side of the Yangtze River. In 1968 the first bridge crossing over this river was built. Until a short time ago this was the only connection between the two parts of the city. In order to reduce traffic congestion, the 2nd bridge of Nanjing was built in 1997.

With a total length of 1’238 meters the 2nd bridge of Nanjing was the longest cable stayed bridge in China, at that time. The carriageway deck of the 410 million dollar bridge is approximately 37 meters wide and hosts 6 lanes of traffic.

The maximum movement capacity of the type LR20 lamella joint is 1’600mm. Due to its heavy weight the assembly of the waterproof joint had to be done on site, on the bridge. In order to improve driving safety in wet conditions, the joint was coated with a special anti-skid surfacing.
