The Mpumalanga Department of Public Works, Roads and Transport warn motorists not to use the D25z road near Brakfontein in the Delmas area.
The road is closed after it was damaged by the heavy storms.
The road joins the R50 road (between Delmas and Leandra) and is mostly used by people working in the mines around the area.
It is alleged that during the heavy rains, a truck drove on the road and it collapsed.
Rescue teams are still at the scene to ascertain if there were no people affected during this incident as illegal mining is rife in the area.
