One of the longest cable-stayed bridges in the world
INDUSTRY, INNOVATION AND INFRASTRUCTURE
Build resilient infrastructure, promote sustainable industrialization and foster innovation
Economic growth, social advancement and action against the climate emergency depend largely on investment in infrastructure, sustainable industrial development and technological progress. Today, about 1 billion people live more than 2 km from a roadway, 940 million live without electricity, and 663 million lack improved drinking water sources.
ACCIONA participates in the entire infrastructure construction value chain, from the identification of opportunity, design and execution, to the operation and maintenance of the constructed works, using the most advanced and innovative techniques.
Performance quality and safety are two of the criteria that maximize the company's value proposal in the development of large infrastructure projects and that differentiate it from other competitors in the construction field.
It is a 1,177 m long cable-stayed bridge that forms part of Route 3, which connects the north west of the New Territories with the island of Hong Kong.
The bridge supports two separate decks on both sides of the three towers. Each deck has three lanes for traffic and a hard shoulder, making the bridge appear more streamlined while withstanding high wind speed conditions.
It has three towers, designed to withstand extreme winds and typhoons with heights of 170, 194 and 158 meters. The central pile, founded on stilts, has been built on an artificial island in the Rambler Channel (China Sea).
Among its many characteristics, it is worth highlighting two world records achieved during its execution:
- Double cantilever: 278 meters on each side of the central pile.
- Longest cable: 465 meters in length.
- Location: Hong Kong, SAR, China.
- Contract type: Design and construction.
- Infrastructure: 1,177-metre cable-stayed bridge and access roads.
- Year of project completion: 1998
- At 1,177 m long, the Ting Kau Bridge is one of the longest multi-span cable-stayed bridges in the world. It has three towers, designed to resist extreme winds and typhoons, which are 170, 194 and 158 metres tall, respectively. The central pylon, supported by piles, has been built on an artificial island in the Rambler Channel (China Sea).
- ACCIONA, a leading infrastructure and renewable energy company, designed and built the Ting Kau Bridge – one of the longest in the world at 1,177 metres – in Hong Kong, China. This bridge has a maximum height of around 200 metres and connects the north west of the New Territories with the island of Hong Kong, serving to provide access to the important Hong Kong International Airport.

Tecnology and innovation
heavy lifting equipment
With the help of heavy lifting equipment, installed on top of the pylon, the metallic structures to house the cable tie anchors were mounted.
The lifting equipment consisted of a metal structure on a corbel with two 200-tonne jacks at each end. The system was computerised and allowed movements and turns on all three axes, which were carried out with the help of hydraulic components.
