The department of transport has warned motorists to steer clear of the M4 between Umdloti and Umhlanga because the road is “sinking” and has been closed.

Authorities didn’t know why the road had started to sink, but that engineers were evaluating the situation and suspect poor maintenance.

The M4 southbound, from the Umdloti interchange to the Umhlanga off-ramp, is the affected part of the highway.

If you live in Ballito or other areas north of Umhlanga, and you normally travel on the M4, be sure to carry an extra cash with you for Toll fees.

Tongaat Toll plaza would be happy with this closure as motorists will have no choice but to cough up and pay to get to and back from work.
