Sicilian Suspension Bridge to Go Ahead 392
SpanningTheGap writes "According to the BBC, Italy plans on building a suspension bridge connecting the Italian mainland with the island of Sicily. The bridge will be five kilometers long and its central span will be over three kilometers long, easily breaking the old record length for a suspension bridge. The artist's conception image of the monster is a sight to see. Another article with more info can be found here." There's a website with assorted technical info about the design.

A good example is the hawaiian island of Kaua'i.
There have been some comical failed attempts to make the main highway (Kuhio Hwy, but it changes names) go all the way around the island (I think the earth moving machines are still stuck in the swamps to this day).
Since it never happened there are still out of the way places. Never mind that it isn't a huge gap, and that driving from one extreme corner of the island to the other takes less time than it does to drive from New York to D.C. (2 hours as compared to 4-5 (depends on how fast you drive!))
that little element of inaccesibility and that lack of convenience tends to preserve the outer corners.
But I don't think there will be any threat to sicilian culture. With the way italians drive, the mere threat of an accident on that bridge will stop most people in there tracks.
-P.S.- don't bug me on the italian digs. I'm full blooded and yes I've been there.

Since the Channel Tunnel was 31 miles long, it seems a suspension bridge was not really a valid option.
I imagine a tunnel is a lot more expensive to construct than a bridge, so it makes sense that if a bridge is a viable option, then that is the one the project engineers should take.
Re:Chunnel (Score:5, Insightful)
I wonder if their argument is a bit backwards. The situation in Sicily might be caused by the fact that they have no good access to the mainland. With easier access both ways, it might result in changes to the island social climate such that the problem will end up being solved as a byproduct.
In some ways, "build it and they will come" might actually work. Much sillier things have happened.
I will admit that the bridge's price tag is HUGE. Such a move has a lot of risk and should be considered with all due care.

If the Gibralter Bridge is ever built, I predict it to be an incredible boost to the economies of both Europe and Africa. Industry in Europe could gain by getting cheap labor in Africa, while nations in Africa will receive heavy investments - Improving their infrastructure. Surely it would be a Win-Win situation for both Africa and Europe.
Like the Tunnel connecting France and Great Brittain, I think it is likely bridges like these would only be feasible if high speed railways are used. High speed railways would allow more traffic and therefore higher revenues to help offset the costs. Unfortunately, I don't think Railways at the southern Regions of the Italian Mainland are currently up to the task. As Americans, we might fail to realize that railways are a primary mode of transportation in most of Europe. Although Expressways do exist, Many people choose to not drive at all because train rides are cheap yet convienient.
It is my belief that the Sicilian Bridge will require much greater investments than the bridge itself to become sucessful. Traffic is what pays for gigantic projects like this, and without high speed railways and expressways it may be difficult.

Well, there are already hundreds of thousands of immigrant moroccan workers in Spain.

But the biggest is hardly the transportation; bridge would do nothing for real barriers for free flow of labour (legal barriers as labor unions in Europe are afraid of cheap labour, governments worried about social problems etc etc)
And as to investments to Africa, money need not be transported via bridges... lack of investments is not really caused by missing road infrastructure between Europe and Africa but by total lack of interest. Africa is about the worst place to invest, and has been for past couple of decades. Sad but true. :-/
In short, even though bridge would have its uses it's unlikely it would have huge impacts on any nearby economies.

If there are no pylons in the water as planned, disruption during construction should be minimal.

The articles stated that the bridge will be some 230+ feet above sea level which allows enough clearance for US aircraft carriers. That should leave plenty of room for cargo ships.

I took a tour of Boston's Big Dig [bigdig.com] project a couple of weeks ago, including the Leonard Zakim cable-stayed bridge [bigdig.com] across the Charles River. The head engineer for the project went over the design considerations, including the properties they needed in the cables. He showed us a few different kinds of cable, including ones meant to flex, ones meant to be stiff, etc.
Ultimately, it seems like a fascinating materials science problem. You spec out what properties you want your bridge to have (amount of traffic, hence average & maximum weight load, resistance to winds & seismic activity, etc) and then find cables that can support that specification. For the Zakim bridge, the inner cables will be under a light load, and won't be twisting much, so the cable needed doesn't need to be as strong. The top/long cables have to be able to flex, resist 200+ mph winds, and will be bearing the greatest load, so the steel chosen for the purpose is picked to match these needs. It's all quantitative science, not guesswork, and I'm sure the prople designing the Sicilian bridge are just as clueful.
