The Umlazi River Bridge on the P177 route, in Mpumalanga, has collapsed.
As a result, the Chief Albert Luthuli Municipality closed the road between the R33 and N17 until further notice.
The exact location of closure is between R33 and N17, ( Carolina to Chrissiesmeer).
It is not clear how long the road will remain closed, but the Municipality said in an update, it will be just until inspections and repairs are completed.
Motorists are advised to use alternative routes.
