Sicilian autostrade/motorways

[hiflier]

Drive between Catania and Palermo on the dual-carriageway autostrada and you cannot but be impressed by its construction - much of the road is on stilts about 20 feet above the ground. It has been suggested that the Mafia had a hand in this, taking a large percentage of the construction costs for themselves. But my question is this: in a couple of places, one carriageway actually crosses over the other, and for a few kilometres they run parallel to each other but 'the wrong way round', ie traffic seems to drive on the left hand side, not the right. Does anyone know why this was necessary?

On Google Earth, most of the images of Sicily seem to be in high definition. Could you specify where the area you refer to in your question is?

I think I found it on Google Earth:

14�03'15.00" E

Now all we need is the answer to your question!
