Kap Shui Mun Bridge, Cable-stayed bridge in Ma Wan, Hong Kong.

Kap Shui Mun Bridge is a cable-stayed bridge on Route 8's Lantau Link, spanning the Kap Shui Mun channel between Ma Wan and Lantau. Its two H-shaped towers rise 150 metres, giving 47 metres of clearance over the water. The upper deck carries three lanes of road traffic; the covered lower deck holds two MTR Airport Express and Tung Chung line tracks plus two single-lane emergency roads.

Construction began on 21 December 1992 under a HK$1.643 billion contract, and the bridge opened in 1997 as part of the Lantau Link serving the new Chek Lap Kok airport. It was then the world's longest road-rail cable-stayed bridge, a record held until Denmark and Sweden's 490-metre Øresund Bridge opened in 2000. In 1997 it received the Japan Society of Civil Engineers' Tanaka Award.

The name Kap Shui Mun comes from the marine channel the bridge crosses between Ma Wan and Lantau. Because the lower deck carries both the MTR Airport Express and Tung Chung line tracks, the bridge is a rail and road crossing rather than a road-only link. Its 1997 completion brought the Japanese Civil Engineering Society's Tanaka Award, one of only three Hong Kong bridges so honoured.

The bridge is primarily accessible by car or train on the respective decks, with no pedestrian crossing available. Visitors can best view and appreciate the structure from nearby viewpoints or while traveling across it.

The bridge was constructed using an innovative assembly system where prefabricated segments were floated into position and connected in sequence. This building method was advanced for its era and allowed the project to progress without extensive temporary structures.
