I love these kinds of roads; the trees form a tunnel that makes me feel like a Formula 1 driver - only without the Formula and without the 1. Not that I'd actually be able to drive at those speeds on our roads as, irrespective of the actual day of the week, there's invariably a Sunday-afternoon-cruiser enjoying the drive somewhere ahead of me. At times like these I need to remind myself that it's okay, perhaps even good, to drive s-l-oooooo-w-l-y. :)
Congestion on Cape Town's roads has been increasing steadily over the past years, with the effects being felt more intensely since the 2010 Soccer World Cup construction work began. Large alterations are in progress at the N1/M5 interchange near the city, as well as at Hospital Bend, which look as though they'll improve the rush-hour traffic problems significantly.
Believe me, most of Cape Town can't wait for them to be done!
Take a look at this 2008 article detailing the intended upgrades.
