HONG KONG - Erection of the prefabricated double-arch steel bridge for the Cross Bay Link in Tseung Kwan O, which is also the largest component of the bridge, was completed on Friday.

This is the first time the “float-over method” has been applied for bridge construction in Hong Kong.

The cross bay link in Tseung Kwan O is about 1.8 km long, of which 1 km is a marine viaduct and the steel bridge is an integral part of the marine viaduct.

Upon completion, it will be the longest span and heaviest steel arch bridge in Hong Kong and another landmark cross-sea structure.

“As the double-arch steel bridge weighs over 10,000 tons, the project team adopted the 'float-over method' and took into account the tidal conditions for its erection,” said a spokesman for the city’s Civil Engineering and Development Department.

The entire process, which began at around 7 am, lasted about five hours.

“The project team has conducted a meticulous analysis of every step to ensure smooth execution of the erection process,” the spokesman said.

Kan Jun, director of the China Road and Bridge Corporation which is the contractor of the main bridge of the project, said it was a breakthrough that high strength S690 steel is used for arches of the bridge.

To increase efficiency, the 200-meter-long steel bridge components were prefabricated in the mainland and the bridge was delivered to Hong Kong on Jan 16 from Nantong, eastern Jiangsu province.

Spanning across Junk Bay and featuring a carriageway with a cycle track and footpath, the Cross Bay Link will connect the southeastern areas of Tseung Kwan O with the Tseung Kwan O-Lam Tin Tunnel. The project is scheduled for completion in 2022.
