N2 Mhlali River Bridge
The April 2022 floods caused the overtopping of the Mhlali River Bridge deck which carries the Northbound carriageway approximately 9km North of Ballito. The horizontal hydraulic forces (including forces due to debris carried by the river) and vertical lift forces had caused the deck to displace off its bearing supports and in a downstream direction. Extensive scour of the approach fills behind the abutments had left the approach slabs of the bridge unsupported.
The repair and jacking of the Mhlali River Bridge (North-bound) into its original position, and to repair the bridge approaches after the April 2022 floods. Currently the north-bound traffic is diverted before the bridge repair onto the south-bound lanes and diverted back to the north-bound lanes after the bridge repair. These delays currently cause frustration amongst road users and commuters in both directions over this 3km stretch on the N2 freeway.
