Light at the end of the traffic jams?

Anyone who has had the misfortune of having to negotiate the hell run that is the stretch of road from the bottom of Ou Kaapse Weg through Sun Valley and Capri Village to Kommetjie will be observing the progress of the massive roadworks with bated breath. For years the poor layout of the roads, with multiple traffic lights, double lanes bottlenecking into single lanes in the most inappropriate places, all exacerbated by some of the most unskilled drivers on the planet, has been a source of stress for commuters who spent up to two hours on a bad day getting through 3 intersections.  Some succumbed to the inevitable and sold up, moving from a quiet seaside village that was impossible to leave or get to if you were in a hurry,  to a suburb more connected with the world. Those that remain have become accustomed to adding an hour to travelling time at peak hours, and getting up at 5.30am to 'miss the traffic' is the norm.
Since the road widening began (and one is forever grateful for the foresight of town planners for leaving the space), a miracle has been performed by the contractors.  Estimated to take around 30 months to complete, and with no stop/go allowed (they learned from the 8-year project between Fish Hoek and Muizenberg - some children went through their school days without one clear run), there are definitely signs that they are on the home stretch.
We have been treated to a constantly changing layout, sometimes with one lane, or two, and lately even a surprising third. The lanes change frequently and one can't go shopping and be confident that the same route will be taken on the way home. Night time is even more exciting, with only reflective chevrons to guide you home - the street lights have still to be replaced once the new gutters and islands are in place. The traffic lights move around in 44-gallon drums, but as is the norm, nobody takes much notice of them. Desperate times call for desperate measures, and many feel that running a red light is insignificant in exchange for a place a few cars ahead.
It remains to be seen if these elaborate changes are going to have the desired effect, given that the driving skills of the road users still fall far short of acceptable, let alone competent, and I have a list of potential areas where the best laid plans will probably 'gang aft agley'.  Time will tell.
