Tseung Kwan O (TKO) develops prosperous constantly. Cross Bay Link (CBL) and Southern Bridge under construction will promote the accessibility and the overall development of the district, creating a whole new look of TKO.
Accessibility
Enhancing TKO internal and external road networks
The journey time during peak hours between TKO and Eastern Kowloonwill be reduced by about 20 minutes by travelling through the CBL and Tseung Kwan O – Lam Tin Tunnel.

Connectivity
CBL is the first marine viaduct containing carriageway, cycle track and footway in Hong Kong.
Both CBL and Southern Bridge designed with viewing platforms for visitors to appreciate stunning sceneries of Junk Bay and Eastern Channel.
Landscape
Green strips are designed along cycle track and footway, making CBL to blend into the scenery.
The green strips along CBL serve as dividers between the carriageway, cycle track and footway.
CBL is an about 1.8km long dual two-lane carriageway with a cycle track and a footway across Junk Bay. Mainly composed of marine viaduct across Junk Bay, CBL connects Tseung Kwan O – Lam Tin Tunnel (currently under construction) and Wan Po Road to and from LOHAS Park or Tseung Kwan O Industrial Estate, to relieve the heavy traffic on TKO Tunnel, TKO Town Centre and Wan Po Road.

Southern Bridge is an about 150m long footbridge to enhance pedestrian connectivity between promenade areas on both sides of Eastern Channel.

The main bridge of CBL and Southern Bridge are both steel arch bridges, echoing with the Northern Bridge over Junk Bay and Eastern Channel.

The concept of “Eternity Arch” is opted for CBL main bridge. It appears as a mathematical symbol of infinity “∞”.
Southern Bridge
The form of Southern Bridge is akin to waves rippling between Junk Bay and Eastern Channel.

Creative Construction Methodology
Both CBL and Southern Bridge adopt modular construction methodology
Prefabrication of steel arch bridge at Mainland yard
Prefabricated components transported to Hong Kong by sea
On-site installation of steel arch bridge
Methodology of Erection of CBL Main Bridge
Erection of steel arch bridge by Float-over Method
1
Moving to a position 30 metres from the bridge piers for final preparation
2
Moving in between the bridge piers during high tide window
3
Precise positioning of the main span by 3D Jacks
4
Completion of erection
Advanced Technology & Material
Both CBL and Southern Bridges have extensively adopted Grade S690QL high-strength steel in their steel bridge structures. Compared with common structural steel, Grade S690QL high-strength steel processes greater tensile strength, enabling the bridges to use less material under the same loading condition. It also enhances the aesthetic appearance of the bridges, as well as scales down the piers and substructure, thus reducing the carbon footprint and improving the sustainability of the projects.
