Husab Mine Access Road

Bankable feasibility study, design and construction of a new 22 km long surfaced road and a 160 m long bridge over the Khan River. The first 4km section is over a relatively flat terrain before descending into moon landscapes, with rough terrains consisting of solid granite rock, which constituted massive blasting operations. 10 km of the route runs within tributaries of the Khan River, with 3 km within the Khan River itself. The section within the river is positioned on the northern embankment of the river and is protected with gabion boxes and mattresses over the entire length. The last 3km of the route is on the relatively flat Welwitchia plains.

All stormwater infrastructure on the project was done by a labour-based SME contractor. The bridge over the Khan River is the longest bridge constructed in Namibia since independence. The bridge was designed for a single carriageway road and comprises 8 simply supported 20 m long deck spans, carried on solid circular reinforced concrete piers with deep piled foundations within the river bed.
