4th Macau-Taipa Bridge, Macau

A much-needed alternative link

Arup is providing project management, cost management and site supervision consultancy services for the 4th Macau-Taipa Bridge – another vehicular crossing linking the Macau Peninsula and Taipa.

The bridge will mostly consist of approximately 3km long marine viaduct, crossing two navigation channels and located on the east side of Ponte de Amizade. It will have eight traffic lanes, two of which are exclusive for motorcycles – a first in Macau. The bridge will also be equipped with wind shields to ensure safe driving during typhoons.

Upon completion in 2024, the project will relieve the increasing traffic flow between Macau and Taipa and help meet the demand created by the Hong Kong-Zhuhai-Macao Bridge and future development of new reclamation areas.

Ensuring construction safety

The bridge features a typical 48m-wide steel deck section at the approach ramp and a truss structure for navigation spans. Most of the steel deck segments were installed by a bespoke lifting barge with load capacity of 2,200 tonnes.

One of the biggest challenges faced during the construction was to launch the 60m wide deck segment in place at the shallow water area. A temporary platform with a guide rail system was designed, leading to the deeper water area where the lifting barge could be manoeuvred. This allowed the deck segments to be pulled into the designated position along the rail, and welding could be carried out between segments.

During the process, we attached great importance to the detailed planning of the operation and site safety to ensure segment stability.
