Oh yes, those old engineers were masters lady Joan and it's simply amazing how they coud beat the odds.
I think that you are talking about the Du Toit's pass tunnel as there's no tunnel on the Bains Kloof pass and the security stops were there to control the traffic of the residents, as many sections of the pass were cut the single lanes, as the roadworks were repairing the pass.
So one would stop and wait if a car was in the pass, until it came past and then they would give us the green flag.
Only one car can fit on this single lane and the drop on the right hand side is a mile down, so it would be madness to try and pass on the right in some places.
According to history Bain did try to build a tunnel there, but it collapsed and he abandoned the idea, as he then cut a path around the mountain.
We had some tricky parts but nothing serious and it was exhilirating to drive so close to the mountain peak. I call it the place of true silence and no wonder that there is a big Christian camp up there.
Unfortunately they have not used it since the start of Covid.
Here's my secret to be allowed entry to the pass, as it's only open to residents.
The big chief of the roadworks is our friend and also our neighbor here at home, so he invited us for a braai as he stays up there in a cottage and we look after his house here.
Funny how life works out sometimes.
Blessings to you guys.
