The road between the Mpumalanga Lowveld and Swaziland via the Josefsdal border post is an important regional link, taking the tourism potential of the area into consideration. The upgrading to a provincial road standard made this the preferred route between Nelspruit, South Africa, and Mbabane, Swaziland. A special feature of the road is the exposure of the unique geological features of the area.
The upgraded route followed the existing alignment, except in a few short sections where the road was re-aligned in order to improve the geometry. The upgrading of the road involved the widening of the road width, requiring significant retaining structures and reinforced earth infrastructure. The design and construction had to meet strict environmental requirements and was subject to the supervision of a full-time Environmental Control Officer to ensure the integrity of the indigenous forest and water- ways.
Local suppliers were engaged in the project in order to achieve the minimum 23% local content, i.e. involving the communities and businesses in the influence area of the road.
A low level crossing at Mlomati River was replaced by a bridge. This road is located in a mountainous area and required major safety improvements such as guardrails and chevron signs. The project was completed on time, within budget and to the specific requirements of the client.
