Kap Shui Mun Bridge

The Kap Shui Mun Bridge in Hong Kong is the world's longest cable-stayed bridge carrying both road and railway traffic, with the upper deck for motor vehicles, and the lower deck for both vehicles and the MTR. It has a main span of 430 metres and an overall length of 1323 metres and, because it spans the main marine channel between Ma Wan and Lantau, its vertical headroom is more than 40 metres above sea level. Along with the Tsing Ma Bridge and Ting Kau Bridge, it is closely monitored by the Wind and Structural Health Monitoring System (WASHMS).
