Right thats me driving to work through Houtbay and Campsbay for the next few years. Nice drive but extra petrol for all those hills.
Hmm... that might work as an alternative route.... will probably still be faster than sitting in the traffic at hospital bend!
Incidentally, you notice how they say that 2 lanes will be open in each direction at all times - but which two lanes? Seeing as there are 3 different destinations, will you still be able to get to each turnoff?
