Construction starts on N$239m road project
Multidisciplinary construc-tion and engineering group Aveng Grinaker-LTA has started upgrading the B1 national road between Windhoek and Okahandja, in Namibia, to a dual carriageway at a cost of N$239-million.
Most DangerousThe road is considered the country’s most dangerous, owing to the large number of heavy vehicles it accommodates, prompting the Namibia govern- ment and roads authority to upgrade it to a dual carriage- way.
Aveng Grinaker-LTA will upgrade a 10 km stretch of the road.
The project will also include 691 000 m3 of mass earthworks and 324 000 m2 of single-seal surfacing. Two interchanges will also be built, each with a north- and southbound bridge.
Further, a 4.5 km service road will be constructed to create access to the plots next to the carriageway.
The project is expected to be completed by April 2016.
Aveng Grinaker-LTA civil engineering divisional MD Richard Evans tells Engineering News that the road construction will not require major traffic diversions.
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.
“Owing to the new road being an upgrade from a standard two-way national road to a double carriageway, it will remove the danger of having to pass slower vehicles while facing oncoming traffic. “The other benefit [the allevia-tion of] the build-up of traffic during peak hours,” said Evans.
