The Johannesburg Metro Police said all lanes of the N1 South are closed to traffic.
This follows Monday afternoon’s motor vehicle accident, involving two trucks on the N1 South- before Maraisburg Road.
Authorities said there were three minor injuries reported, and one of the trucks has overturned, spilling diesel.
As a result, closure is necessary to allow emergency personnel to safely manage the scene and clear the diesel spillage.
Emergency personnel and Law Enforcement are at the scene, and initially, three lanes were affected and closed off, causing heavy delays.
All lanes of the N1 South are now closed before Maraisburg Road.
Vehicles are being diverted at Gordon Road.
The N1 South is expected to be reopened in the next 4 hours.
