Talking of Sicilia, are they still pretending the Messina Strait Bridge is under construction? What is the current status. I really hope this bridge will be constructed, but it's been postponed numerous times so I'm rather sceptic about it. Since the Norwegians are considering a floating cable-stayed bridge for the Sognefjord crossing, I'm wondering whether this a good idea for the Messina Strait as well. It's technically possible (the offshore industry uses large floating rigs for decades), plus it may give some additional flexibility in case of earthquakes.

The bridge was officially cancelled by Monti government. The bridge could be cool but also very expensive and possibly dangerous (seismic risk). I think the South has other priotities now. I don't think the bridge will be completed anywhere in the next 30 years.
The strait is around 500 meters deep, to much for a tunnel.

That's no problem for Norway. Some Norwegian tunnels go almost 300 meters below sea level.

Sorry, I made a typo. The dept is around 500 meters, not 100.

Ah, then the floating cable-stayed bridge may be worth considering. A tunnel is technically feasible, but it would need very long ramps which are not suited for motorway traffic, not to mention when you want to combine it with a railroad.

A huge suspension bridge with a main span of 3 kilometers has never been done before, especially not in combination with a railroad. Since suspension bridges are relatively light, they are not as suitable for rail freight. There are very few suspension bridges with a main span over 1 km with a railroad.

The longest single-span bridge in the world it's in Japan and is less than 2km long. It was built in 12 years and it's only for road traffic. And our politicians said that we could build the Messina bridge in 6 years...

Some photo's of the beggining of the french A8, right after crossing the border from Italy:





Really low speed limits!! Even taking into account it's a 6% downhill. Here in Portugal it would probably have only a 100Km/h limitation (like many 6% downhill cases on A25, for example).
Still, as this A8 has a huge amount of traffic(and many trucks), I guess it's comprehensile.

I don't know the exact figure but the deepest point is beween 100 and 150 m below sea level, half of this distance made by rock, the other by water.

According to Wikipedia, the Seikan rail tunnel of similar length is deeper, at 140 m below sea bed and 240 m below sea level.

No. The bridge over the Strait of Messina has not been 'cancelled' but put in 'stand-by' the Government Monti, who gave a limit of two years to find investors that invest in the project.

The tunnel, in part due to technical problems (slopes), it would be too expensive.
