This bridge was built to help provide access to the airport, and it is still [2023] the longest suspension bridge that can handle trains.
"It is 41 meters (135 feet) wide and about 2.2 kilometers in total length. The main span is 1,377 meters (4,518 feet) long. It has two decks. The top deck has a six lane highway, and the bottom deck can handle two trains at the same time. The bridge has to be able to withstand a heavy load and severe typhoons. The towers are 206 meters (676 feet) tall. The span is the largest of all bridges in the world carrying rail traffic. It looks like a heavier version of the Golden Gate Bridge. In comparison, the middle span of the Golden Gate Bridge is about 1,280 meters long (4,200 feet).... Construction started in May of 1992 and ended in May of 1997."

 

The clearance is 79m (260'). [BillBrown'sBridges]

It was the second longest suspension bridge when opened in 1997. The lower deck also contains two enclosed road lanes that are mainly used for maintenance. But they can also be used for emergencies during high winds. [ice]

They not only wind-tunnel tested the completed bridge, they tested various stages of construction to schedule stable versions of the bridge to stand during typhoon seasons. Each cable is 1.1m (3.6') in diameter. Each approach span has an expansion joint that accomodates a thermal expansion of 0.835m (2.7').

"The bridge was built by a partnership of construction contractors from the United Kingdom, Japan, France, Hong Kong, China and Switzerland."

"The deflections of the bridge are 4.7 meters in the vertical; 1.3 meters due to temperature changes; 4.4 meters laterally due to wind. Longitudinal movement is at ±835 millimetres at the Tsing Yi abutment. Traffic speeds on the bridge are 100 km/h (60mph) for automobiles and 135 km/h (84mph) for trains."  [structurae]

The towers were built using slipforms in just three months.
