Recently, the Sengkang Kat Bridge in Sarawak, Malaysia, constructed by CHEC, successfully completed its mid-span closure.

With a total length of 1,281.2 meters and main towers reaching 119.06 meters in height, it is the world's largest harp-type twin-cable-plane, twin-pylon concrete cable-stayed bridge.

The bridge's design blends local Malaysian architectural elements with innovative solutions tailored to the region's geological conditions, climate, and traffic demands.

The main towers combine functionality with visual appeal. The innovative design of the side piers significantly improves structural stability and extends the bridge's service life. Except for the prestressed structures used in the mid-span closure section and side-span cast-in-place sections, the remaining main girder sections adopt a non-prestressed design, simplifying construction, reducing costs, and ensuring structural safety.

The 5-meter-long mid-span closure section was completed using an innovative jacking system and a seven-stage jacking process developed by the project team to withstand a jacking force of up to 2,000 tonnes.

Once opened to traffic, the bridge will further improve Kuching's transport network, enhance travel efficiency, and inject new momentum into Sarawak's economic and social development.
