Multidisciplinary construction and engineering group Aveng Grinaker-LTA has started upgrading a 10-km stretch of the B1 national road between Windhoek and Okahandja, in Namibia, to a dual carriageway at a cost of N$239-million expected to be completed by April 2016.
Because of the large number of heavy vehicles it accommodates, the road is the country’s most dangerous, prompting the Namibian government and roads authority to approve the upgrade.
The project will also include 691,000 m3 of mass earthworks and 324,000 m2 of single seal surfacing. Two interchanges are included, each with a north and southbound bridge.
A 4.5-km service road will also be built for access to the plots next to the carriageway.
The northbound carriageway can be built without major interference with the existing road, after which the traffic will be moved onto the completed northbound carriageway to allow for construction of the southbound carriageway.
