Italy To Build World's Longest Suspension Bridge 202

Posted by Zonk from the getting-places-in-a-hurry dept.
Rei writes "According to the BBC, Italy has just granted contracts to begin work on the world's longest suspension bridge, connecting the island of Sicily to the mainland. The nearly four kilometer-long bridge across the Messina Straits is to carry a double six-lane highway and four high-speed railway tracks. Its main span will be 3.3 kilometers long; this would over 1.5x the current record-holder, the 1991-meter Akashi-Kaikyo bridge."

  • It's impressive, but I think that the goal of bridges is to be as short as possible (although in this case, that's obviously the shortest length it can be).

    But, consider having a car accident or car trouble on the a bridge... it'll cause havoc. And the longer it is, the harder it will be to mediate such problems.

    In either case, it's still cool.

      why would it cause "havoc"? Surely it will be heavily monitored live by camera and other methods. It's going to be a double six-lane highway!! There's no reason one of the lanes couldn't be reserved for emergency traffic. Also, it's only 2.5 miles long. Huge for a bridge but nothing special otherwise. You could therefore reach any point on the bridge in about a minute. I have to say I'm not seeing any show-stoppers here.

      There are plenty of bridges that are longer than that and they serve their purpose well. This is just the longest suspension bridge. I've personally used the 23-mile bridge-tunnel across the Chesapeake Bay [wikipedia.org]. Also consider the Lake Pontchartrain Causeway [wikipedia.org], it's 23 miles all above water. Neither of them are as wide as this bridge is proposed to be, either.

          I don't doubt that at all. Being two lanes in either direction it doesn't lend itself to allowing traffic to flow around them. Though, a bridge as wide as the one proposed, with the (comparatively) short distance proposed, shouldn't have as much of a problem.

    • There are many bridges that are longer than this; for example, the Lake Ponchartrain causeway, for example, is (or was, if they haven't fixed it yet) 24 miles long! Moreover, it's only 2 lanes in each direction, so accidents clog it up much more easily.

      The only thing special about the Messina bridge is the span -- the long causeways in America cross shallow water, and therefore can be supported at much more frequent intervals.

    I am slightly surprised that this project is expected to cost at most as much, if not less, than the extected cost of seismic retrofit for the relatively shorter San Francisco-Oakland Bay Bridge [wikipedia.org] (that project involves the construction of a completely new replacement for the eastern span of the bridge). How come? I suppose one reason is that the cost of everything in Bay Area is much much higher than in southern Italy. What about other factors? Is there something that makes the Italian design inherently cheaper to implement?

      Different constraints - the portion of the San Francisco-Oakland Bay Bridge has to fit with the rest of it and the bridge will presumably be in use while construction is going on. The Italy-Sicily bridge just has to cover the distance, doesn't have to fit to a pre-existing design and doesn't have to be used until it's finished.

      In a lot of places you will see bridges built next to each other - sometimes it's cheaper to build a whole new bridge instead of tacking another bit on the side.

      The cost of stuff in the Bay area are most likely irrelevant to the project, since stuff will come in from elsewhere.

    • "How come?"

      Italy doesn't have to deal with CalTrans, or the fifty gazillion other state and Bay Area agencies with noses in the project. I believe California's nuthouse approval processes have long eclipsed even the famed Italian bureaucracy.

      Instead of a concrete skyway like in the Florida Keys, the mayors of Oakland and SF, with the general backing of the Bay Area residents, wanted a signature span instead. The final design has never actually been built anywhere in the world on this scale. Consequently when bids went out for contractors, only one company decided to bid and get involved in this very political situation. Well that bids was far more than expected. Meanwhile over the years the cost of steel has increased dramatically, particularly steel made in the USA, which was a requirement for this project.
      • Hey, don't blame those of us in SF and the peninsula for the "signature span"... our side of the Bay Bridge looks awesome (when it's not being retrofitted).

      A bridge costing 3,880,000,000 Euro to save 20 minutes

      Attacking the Messina Bridge is like attacking the Red Cross. This is plain even to an idiot who is completely useless, even though he is useful to the interests of someone.

      After the ad hoc laws, we now have the ad hoc construction work.

      The bridge is of no use to the Italians, including those from Reggio and from Messina, divided by nature for a million years. To go from Salerno to Reggio Calabria, it takes 48 hours. Then the bridge will allow you to save 20 minutes to get to Sicily.

      The country has other priorities that are real. Motorways and railways are in an abysmal state.

      The 3,880,000,000 Euro are ours. Why should we spend them for a useless construction? Our employees, incapable of managing our public debt, before spending the money for the bridge should explain how we will get a return on the money, and explain the utility, the environmental impact and the do-ability.

      A 3,000 metre bridge with an aerodynamic profile, has never been constructed up to now.
      There's no guarantee that it will stand up, especially if you consider that it's in a zone of major seismic activity (remember the Messina earthquake?) and with incredibly strong currents.

      On this point refer to the interview with the Professor of architectural construction, Massimo Majowiecki. Some of his conclusions are given here.

      "The Delegations of Superintendence of ANAS {Roads}, of FF.SS {railways} and the Ministry of Public
      Works, in July 1995 conclude: " that the Progetto di Massima Definitivo {the final project plan} presented in December 1992, even given the undoubted value of the information supplied, it is not yet possible to indicate which project is definitely the one to be developed into a construction project, to be translated into the building of a bridge and a global passage across."
      In present conditions, the technical uncertainties stil remain...."

      But the bridge will create jobs and contracts and will get the approval of the Confindustria {employers' organisation} and of the Unions. Perhaps it would be better to get them to dig holes and fill them in again. It's a useless activity, but at least it wouldn't cause harm.
