Zutari, in joint venture, provided the design and preparation of bid documents, as well as site supervision for the construction of the new bridge and its associated approaches and drainage structures.

The 880-metre-long bridge spans a perennial river channel approximately 100 metres wide and crosses a floodplain for 780 metres before connecting to the embankment. Poor foundation conditions led to a design featuring long spans and a lightweight composite steel and concrete deck, offering both strength and economy.

The final configuration used 50-metre spans with dual steel box girders and an in-situ infill concrete slab. Fabrication of 142 box girder sections was undertaken in Qing Huang Dao, China, while 1 384 precast concrete deck slabs were produced on site in Angola. The girders were shipped to the Port of Namibe and transported 600 kilometres by road to the construction site.

An assembly and welding yard was established on site, where girders were welded in pairs and launched incrementally using hydraulic jacks. The composite construction approach enabled concurrent progress: while the concrete substructure was built on site, steel elements were fabricated overseas, optimising the project schedule.
