A large sinkhole on the corner of Snake Road and Golden Drive in Benoni, has led to the closure of the N12 between Pioneer Drive and Golden Drive on the East Rand.
The road has been closed in both directions and the sinkhole has been sealed off.
During a media briefing on Tuesday, 19 November with Gauteng MEC for Public Transport and Roads Infrastructure, Jacob Mamabolo, it was established that the road will remain closed until 2020.
According to a geotechnical team that was onsite during the briefing, the sinkhole was caused by a combination of two things, namely the broken storm water and the percolation of water to the ground instead of it going straight to where it is dispatched in the underground tunnels and not dolomite.
“The phenomena of how it all happens is almost similar to that of dolomite. When we quantify the risk, we quantify it with that of the dolomite standard.” said Thando Sodawe from Geotehnical Investigations.
Sodawe said the official full report will be released on 12 December 2019 with the remedial recommendations.
MEC Jacob Mamabolo, said he went back to the site of the sinkhole, to receive a report from GeoTech experts about the real state of the sinkhole.
“It has become very clear that there is a serious problem that we have to work on. That means, the sinkhole and its depth is growing and this has been aggravated by the recent wet weather conditions.
“It is clear that the road will remain closed for quite some time. We have been assured that from engineering point of view that the problem can be solved. However, it will take a bit longer,” said MEC Mamabolo.
Mamabolo appealed to motorists to respect the fact that the road is closed and give the department the opportunity to solve this problem.
Xolani Mngomezulu of ASEDA Consulting said the report will indicate what needs to be done and how long it will take.
