Temporary Lane Closures on N3-12 northbound carriageway, Gauteng Province

Gauteng, 25 March 2026 – The South African National Roads Agency (SANRAL) wishes to inform road users of planned traffic disruptions on the N3 Section 2 northbound carriageway. The planned closures of the slow lanes are due to the subsidence observed on this section of road.

“SANRAL closed the lanes as a precautionary measure while it investigates the subsidence of the outer lane resulting from possible undermining under the road. Undermining in this area is often associated with illegal mining” said Progress Hlahla, SANRAL’s Gauteng Provincial Head.

“Following the identification of the subsidence, temporary traffic accommodation measures have been implemented on site. These measures included the installation of road markings to divert traffic away from the affected slow lane as well as the temporary closure of the subsidence area. We have also partnered with the Council for Geosciences on satellite monitoring of some of our high-risk areas” added Hlahla.

SANRAL urges all road users to:

  • Plan their trips accordingly.
  • Adhere to the traffic accommodation signage and the flag persons advance warnings, and
  • Exercise patience and caution while navigating the affected area.

SANRAL apologises for any inconvenience caused and the roads agency remains committed to improving the safety and quality of our national roads.
