Tsing Yi Bridge, Road bridge in New Territories, Hong Kong.

Tsing Yi Bridge is a 610-metre road bridge across the Rambler Channel between Tsing Yi Island and the former Pillar Island in Kwai Chung. It has five pairs of pre-tensioned concrete arms supported by stands 18 metres above the water, with round caissons on the seabed. Its hollow box sections carry power cables, two oil pipes and water pipes for Tsing Yi Island. The deck provides 7 metres for vehicles and a 1.5-metre pedestrian walkway on each side.

Construction began in September 1971 under contractor Gammon Construction, funded by a joint venture of six island companies with a HK$7.5 million government contribution. The bridge opened on 28 February 1974, costing HK$21 million, with Governor Sir Murray MacLehose presiding. It was the only fixed link to Tsing Yi until the Tsing Yi North Bridge opened in 1987, after which it was renamed Tsing Yi South Bridge.

Until the Tsing Yi North Bridge opened in 1987, this was the island's only fixed link to the mainland. When the Kwai Chung port closed for typhoons, lorries waiting to re-enter blocked the bridge, and residents grew used to walking across it. On the bridge's tenth birthday, a carnival was held on the football field near Chan Lai So Chun Memorial School at Cheung Ching Estate.

The bridge carries two lanes of outward traffic towards Kwai Chung, with a 1.5-metre pedestrian walkway on each side. It is the only crossing over the Rambler Channel open to cyclists, since the other bridges are expressways or ban bicycles. Ships taller than 17 metres may not pass beneath it.

Protective islands positioned beneath the bridge keep ships at a safe distance and prevent potential collisions that could disrupt traffic flow. This safety system demonstrates how thoughtfully the infrastructure was designed to separate maritime and road traffic.
