Here is the next bridge - Sand River!
As one can see these bridges are not high at all, and carefully designed to be overrun by floods every year, normally only closing them for a day or two.
In an emergency the H12 bridge downstream from the Sabie/Sand confluence can be used in all weather.
The Sand is actually a big seasonal river with a large drainage area outside Kruger, although most water runs under the sand, as they say. It sometimes flows more strongly than the Sabie at certain times of year!
