More heavy snowfall has been reported on the N3 Toll Route along Van Reenen's Pass .
The N3 Toll Concession (N3TC) says a total road closure remains in effect between Estcourt in KwaZulu-Natal and Harrismith in the Free State.
Icy conditions, wet weather, and poor visibility are also being reported along other sections of the route.
This is causing dangerous driving conditions from KwaZulu-Natal through the Free State, the southern parts of Mpumalanga and Gauteng.
N3TC has advised road users to avoid travel to the region.
