- What are the main projects of roads in Italy to the year 2014?

I think that Italy has a near complete motorway system, perhaps the main foccus is the preservation of these roads, I don't know.

Opening of A35 and first stretches of A58 and A36, completion of A1 Variante di Valico, completion of A31, (almost) completion of A3.

Completion of A24 urban stretch (should end in a month actually).


There are still some link that I think are missing: something maybe between Salerno, Potenza/Matera and Puglia, and a good link between Firenze and Fano.

Actually, many of the east - west links, below Bologna, are missing, because of a really mountanious terrain.

Major missing link is Livorno-Civitavecchia.

On a 2nd-order list of important long missing links are:

- Trento-Ponte Nelle Alpi
- Grosseto-Fano
- Sassari-Cagliari

Most critical pending special works is the Ponte sullo Stretto (Messina Strait bridge).

there is a more than decent road between Cagliari and Sassari.

Do you mean Piovene Rocchette?

I would add Mestre - Ravenna among the most important missing links.

The huge missing link Ancona-Rome is being (slowly) filled by a network of superstrade.

You can already travel between those two cities via A24-A14, only 20km longer than the usual route via Terni, Spoleto, Foligno, Fabriano and Jesi.

Ancona-Rome is not just Ancona and Rome. There's Perugia and Terni in between, which are larger than Ancona itself, and there are lots of important towns, like those you already mentioned.

Make that Grosseto - Civitavecchia. The Variante Aurelia, in place between Livorno and Grosseto is a decent superstrada. Though it needs an upgrade, it should not be lower on the priority list.

Last thing I read about Grosseto - Civitavecchia is that the project for a substantial part of that missing link (the Southern section of the A12 would be extensies to Ansedonia) had been approved and that works were going to start in 2014. Is that still on?

Works are already started on that section, namely the Civitavecchia-Tarquinia one:

I would add new Ragusa-Catania.

At the moment it's cancelled because of very high costs and technical challenges (very seismical area). However it's still possible that in the future decades, hopefully with better economy and construction techniques, someone will re-propose this project.
However I'm not optimist about this project. Apart the economic situation, that usually changes throghout the years and it's impossible to made long-term forecasts, there are serious technical challenges.
While 3,6km may look like a ridiculous lenght (in the world there are some 30km+ bridges and dozens of bridge longer than 3,6km exist), the Messina strait it's a particular case. Because of seismical activity, strong marine streams and high depth (circa 500m) it's impossible to build pillars in the middle, only a single span it's possible. The longest single span in the world is about 1,9km in Japan and it carries only road traffic because oscillations would be too dangerous to trains. With 500m+ deep water also a undersea tunnel isn't an option (the lowest in the world is somewhere in Norway, about 300m).

Not so sure about that. Once they extend A18 to Gela, it will be fairly reasonable to travel on A18 to Ragusa and Modica.

A floating cable-stayed or suspension bridge should be considered for the Messina Strait. That way you don't need to construct extremely long spans. This technique has been used in the offshore industry for decades. It's also more flexible with earthquakes.

Could that work for trains as well?

Pillars cannot be put into water, see is too deep, hence the reason for long spans.

With a floating bridge, you don't need pylons to the ground. You only need to anchor it like an oil rig on the continental shelf.

A 3.600 meter span seems quite unrealistic. The 4 longest span bridges are all between 1.500 and 2.000 meters. 3.6 km is another league.

Wouldn't a floating bridge reduce navigability of the Strait?
