Bad news about N1 sinkhole

A large sinkhole next to the N1 in Centurion is now only expected to be fully repaired over three years after it formed, adding further frustration for many motorists.

The sinkhole appeared on the eastern side of the N1 southbound, near the Flying Saucer intersection with the R21, following heavy rain and flooding in January 2022.
 
Centurion is a dump either way, why bother with that crime ridden place?

The Mayor freaking apologized because it took a week to fix.

With a lot of money you can do a lot. You would be surprised the type of crazy expensive stuff they have to do to fix these things so fast. Example - you can't just put dirt in the hole because it will take too long to settle. They use engineered aggregates and do other weird crazy, crazy expensive stuff.

The dolomite in Centurion is a very tricky beast. Not sure why anybody builds anything there. It is like building on a Berocca hoping it won't dissolve when it rains...

Will still be much cheaper than doing it the ANC way, of doing nothing for 6 months, then tendering for 6 months, then replacing the contractor after 6 months of moving dirt around, because they took the money and ran, then doing another 6 months of tendering...........
 
The location also makes it more difficult for motorists from the R21 northbound carriageway to enter the N1 south at speed.

The closed lanes cause a deviation from a normal gradual merge over a longer distance into a sharper and shorter entry into the N1.

This is not very accurate, those R21 people have a whole lane for themselves until after the sink hole road works.

It's been 5 years since the floods in KZN caused a sinkhole on the N2, and they still fixing the road.

They extended the opposite South bound side by a lane so that the North bound (Damaged side) can be redirected to that side of the highway while they rebuild an entirely new road (it looks like)

Well there are ways to compact ground. Saw how they dropped a massive iron block to make the ground more compact for building than it is naturally. We know the reason they don't do these things is not because of what it will cost but the lost income opportunity for cadres.
 
To my amazement the repairs were completed on time but it took years to do.

I wonder how much was wasted/stolen through this project.

I was just coming to MyBB to report this. Repairs completed and all 4 lanes open again (after last weeks bad traffic due to only 2 lanes being open instead of 3).

Yeah and there was no warning of it being reduced to 2 lanes from the usual 3 lanes during construction except where the lanes stopped.

Glad it's over though as it was a shyte show continually.
