The National Road M10 provides an important strategic corridor between Namibia and Botswana in the South and Angola and the DRC in the North.
The initial project required rehabilitation of 103 km of surfaced road between Mongu and Senanga, including complete reconstruction of the 15 km central section. Gravel materials and aggregates had to be transported over great distances and the highly erodable sands required special attention for the outlet of all cross-drainage structures.
Mariswe’s brief included a review of the design consultant’s work, resulting in a redesign with a significant saving in costs for the client.
Mariswe was subsequently appointed for the next leg of the project involving 80 km of the M10 between Senanga and Sesheke. This section was constructed to bituminous surfaced main road standard on a new alignment east of the Zambezi River, crossing the Zambezi near Maziba Bay.
The new road crosses 14 rivers that join the Zambezi, several with large seasonal flood plains.
