Proposed R5.3bn expressway to increase N3 safety, productivity
The South African National Roads Agency Limited (Sanral) recently outlined the benefits of its proposed R5.3-billion De Beers Expressway, saying this would result in significant relief in congestion on the Van Reenen’s Pass route.
Sanral communications GM Vusi Mona noted in a statement that the expressway would result in higher levels of safety, comfort and productivity for road users.
The De Beers Expressway section of the N3 would be a 99 km dual carriageway, which would link Keeversfontein, in KwaZulu-Natal, with Warden, in the Free State.
Although the route was part of the N3 Toll Concession, it would not be tolled between Cedra and Heidelburg, and there would be no change to current toll tariffs on the road.
The route would be 15 km shorter than the N3 and would have flatter grades, a smoother alignment and fewer sharp curves. This would result in a 30-minute time saving for light vehicles and a 60-minute saving for heavy vehicles, as well as better levels of service and a reduction in accidents.
The route would reduce the effects of N3 road closures by at least 80% and remove bottlenecks at Van Reenen’s Pass.
Mona explained that the existing Van Reenen’s Pass route, which was built in 1961, was no longer able to effectively handle the growth in traffic volumes. Increase in Accidents The number of accidents on the route had increased in recent years, resulting in many fatalities and road users being inconvenienced through sporadic road closures.
“The existing stretch of the R103/N3 past Harrismith and across Van Reenen’s Pass will remain in place and continue to be maintained by Sanral. “Once the construction of the De Beers Expressway has been completed, there will be two highways crossing the Berg, providing all road users with an alternative route between Keeversfontein and Warden,” said Mona.
He added that, while businesses on the current route would be affected, not all existing traffic would shift to the new route.
Sanral expected one-third of the through traffic to remain on the current route.
Further, Mona stated that Harrismith would become a “boom town” during the expected four-year construction period.
The N3 route had been earmarked as one of the priorities of the multibillion-rand Strategic Integrated Project 2 that was crucial to unblocking economic development and providing much-needed capacity along key freight corridors in South Africa.
Construction of the De Beers Expressway route formed an important component of plans to develop the Durban–Free State–Gauteng logistics and industrial corridor, which was vital to the future of the national and regional economies.
“With Durban handling over 40% of the country’s imports and exports and Gauteng being the country’s economic heartland, generating over 33% of the country’s gross domestic product (GDP), the Durban–Free State–Gauteng corridor is by far the most important economic corridor in the country and this route will directly contribute about R4.4-billion a year towards South Africa’s GDP,” said Mona.
