Italy’s parliament has finally approved a plan to build the world’s longest suspension bridge between Sicily and the mainland, an area prone to 170 mph winds, powerful riptides and earthquakes.
This suspension bridge across the Strait of Messina will be 2.2 miles long and include two gigantic towers, each 100 feet taller than New York’s Empire State Building. The project could employ 100,000 people in the area and help revitalize Italy’s economically struggling south.
WSJ explains Italy’s technical plans for the bridge, and the engineering developments that may make it feasible.

The bird excuse is used for pretty much all infrastructure projects by people or interests that want to block it, it's not based in any significant reality, when in reality the common house cat kills more birds globally than any infrastructure project ever has.

@javierpacheco8234 17 дней назад

Maybe the cables are invisible and so this causes them to crash. You have to remember that birds have a different vision than us so it makes it more difficult for them to see what we see.

@caevans61 15 дней назад

The Tacoma Narrows example might be a bit misleading. It was not a great example of potential damage due to the speed of the wind, which was only 42mph (67kph) at the time. The wind speed wasn't the issue as much as it was the structure of the bridge that allowed a harmonic resonance to build up within the structure that amplified the frequency of the wind's effect on the bridge, thus causing its collapse. The old trusses were a more rectangular, flat plate design. The replacement bridge used tapered, triangular trusses that improved the wind flow across it, much like what this design uses. I think this bridge's challenge isn't as much the constant high speed of the wind, as it will be the gusts or rapid changes in the speed of the wind. The deck and tower flexibilities will greatly assist in this regard. It will be a great feat of engineering to be sure!

@mattiabolondi9864 3 дня назад

About the Tacoma bridge: precisely! I was surprised the WSJ was so superficial on that! There are even videos of it shortly before the collapse, with cars on it: the bridge is swinging left and right bu the car is stable in the middle, meaning that the wind didn't have enough force to move the car laterally, hence for sure didn't have enough force to make the bridge swinging, hence the bridge is swinging because of something else: the sound.

As an Italian, I can tell you it might really be Sicily. Of course it's not a problem which concerns millions of people, such as in thrid world Countries, but there are indeed some informal settlements like that in southern Italy (sometimes even in the rest of Italy). Often they're populated by irregular migrants working informally in agricultural jobs, but sometimes it's actual Italians who are quite poor.

The problem is not the feasibility or safety of the project, it's the mafia infiltration. Even though, as a Sicilian, i am very much in favor of the bridge being built, i also recognize that building a project of this magnitude without expecting serious mafia infiltration from the two biggest mafia syndicates in Italy (Cosa Nostra and 'Ndrangheta) is folly. It's guaranteed that they'll dip their grubby hands in it to profit off of it. One thing the government could do is actually use the project as a trap, a way to make the mafia leave the shadows and expose themselves, in order to bring them to justice. Sadly, though, this government is very much in cahoots with the mafia and they'll do little to avoid this being a problem.

@giandomenicomartorelli8069 11 дней назад

I agree with you about the analysis on the mafia. But I would like to add that in Sicily they are way more urgent issues where these money could be spent.

@maverickvgc4220 7 дней назад

So what? We should stop doing anything in southern Italy because of the Mafia? Also this project is a massive International cooperation between companies from Italy, Spain, Denmark and Japan, good luck sneaking behind all of them. And this is without addressing the fact that the Mafia's modus operandi for infiltrations always favours low specialization jobs like trash disposal and really basic constructions, not massive constructions that only a few companies worldwide can build.

@Sjalabais 6 месяцев назад

In engineering, I thought you design structures mathematically, then add a safety buffer of typically a multiple of two. If this bridge is designed to withstand an earthquake of 7.5 magnitude and winds of 186 mph, that’s just marginally above the 7.3 earthquake in 1908 and the winds that "can reach up to 175 mph". Isn't that a little...tight?

@jeffreymcgowan2753 6 месяцев назад

The magnitude scale for earthquakes isn't linear, it's logarithmic. According to earthquake.usgs.gov/education/calculator.php, a magnitude 7.5 earthquake is 1.56 times larger than a magnitude 7.3 earthquake, and is 1.99 times stronger.

@johnnyraven4217 19 дней назад

Resonance , not high winds , caused the Tacoma Narrows Bridge collapse. That video is in every first year engineering course curriculum . As for the proposed bridge itself, maybe it’s feasible but maybe a question is should it be built? You can build and operate a lot of super sized ferries for 12 Billion USD. Maybe bean counter number crunchers can tell us the payback period with building a 3km bridge. It would depend partly on bridge tolls versus ferry fares . Also bridges don’t go on strike. So lots to consider.

@KepleroGT 8 дней назад

The main problem with ferries is that the embarking process and disembarkment takes more than the actual length of the crossing. And for cars there is only one ferry company serving the strait, not sure why though, but it does limit the amount of traffic going through. With the bridge you could cross in 5-10 minutes instead of an hour, also the train connections are vital in my opinion so that cargo transportation becomes much faster (at least I hope it does). What is the much bigger problem is the infrastructure that is supposed to connect to it, which is terrible and not well maintained. The government says the building of the bridge will favour the modernization of such infrastructure but I am skeptical.

@blankblank2162 6 месяцев назад

The Tacoma bridge did not fall due to high winds, please update your facts. Even though there were strong winds at the time, the bridge was more than capable of withholding them. It fell due to the consistency of the winds over prolonged periods of time which promoted resonance in the bridge's deck.

@PGproductionsHD 6 месяцев назад

Sounds like it fell due to winds..

@patricksullivan9945 6 месяцев назад

Was going to make the same comment. Winds that day on the bridge were around 45 mph, but the bridge had been design to withstand much higher wind loads. As you said, it wasn't "high winds" that caused the failure but the resonance and amplifying effect of the eddies created by the aerodynamic profile of the bridge. Not the same issue implied by the video.

@johnnyllooddte3415 6 месяцев назад

strong high winds.. there fixed it.. obviously it wasnt capable of resisting strong nor high winds..it FELL

@allo-other 6 месяцев назад

The chief problem was the rigid box-walls design, which "caught" the wind and amplified aeroelastic flutter. If winds had remained low, it would have stood for years. Put simply, it fell because of wind.

@Triplecenturies 6 месяцев назад

The depth of the strait would require the tunnel to start well inland at each end as to prevent a grade train cannot handle.

@nicolaramoso3286 11 дней назад

The strait is too deep.

@carlobrotto7132 8 дней назад

Because the strait is a strong seismic zone , impossible to build a tunnel over there.

It became known which cities of the United States and the United Kingdom were not targeted by Russian missiles. In the UK, Edinburgh is such a city. Russia is confident that after a thermonuclear strike on the NATO bloc, civilization can still be revived in the British Isles. But she must become more peaceful. As for the United States, it is, as in the days of the Soviet Union, the ark on Lake Michigan, namely the city of Chicago and its agglomeration. Russia is confident that this ark will be a new beginning for the American-Canadian civilization. Which will be able to abandon the craving for world hegemony

@sgassocsg 21 день назад

We all know Italians can design, they are the best in the world. However, can they build reliably like the Germans? Anybody remember the last Italian bridge in Genoa?…..poor design and poor maintenance, or how about the cable car in Piedmont? Finally, why? Why build it? Ferry service is reliable and cheap. Just buy 20 more new and modern ferries and the capacity will meet demand. This looks like Vanity, not sensibility.

@flavioric 20 дней назад

Sicily needs to be linked to the continent, and not with ferries that with high waves don't even depart. The bridge will be an incentive for national and international investments, both regarding tourism and trade (EU is the first to want siciliy as a trade hub of the Mediterranean, due to its centrality). Its construction will mean that consequently sicily will receive high speed trains, like those that link Rome to Milan in 3hs, and will be able to cheaply trade and export to the rest of continental Europe. Just for turism, imagine those millions pale Germans, that really love travel by train, that every year come in Southern Italy to get the sun they don't get the rest of the year. It will be an economic boom for southern Italy. The other option is to leave them in a dying island. And nobody wants it.

@Triplecenturies 6 месяцев назад

Tunnel would need to be far longer than 2.5 KM due to the depth of the strait. It would need to start well inland at both ends as to allow a gentile enough grade for trucks and moreso for the trains.

@otaggokcer6875 22 дня назад

why not underwater tunnel? perhaps, more expensive but safer. a tunnel over a fault line? we have a suspension bridge crosses over a very dangerous fault line (North Anatolian Fault) and an underwater tunnel next to the same fault line (Marmaray tunnel)

@republicofhandball8815 20 дней назад

Suspension bridge is the most idealistic construction on Earth, the longer it is, the fragile it is. It's much cheaper then any other type of bridges. If I were them, I would rather make this link an underwater tunnel.

@ethannkyle 18 дней назад

impossible, the strait is insanely deep, and with massive faults running through, you would literally have a tunnel going through areas that would displace the ground meters if an earthquake were to happen, destroying the tunnel

@Triplecenturies 6 месяцев назад

@@oqlassic8799 It does get a bit confusing, but to those in the know, "World’s Longest Suspension Bridge" has for as long as I know has been the suspension bridge with the longest span. Because of the word "suspension", all that is considered is the suspended portion. The approaches leading up to the suspended portion are ho-hum, often short cookie-cutter spans of basic engineering. The Mackinac Bridge in Michigan often gets mentioned as being the longest suspension bridge and a length of five miles is given, but the actual elevated portion is only ~3.5 miles with another ~0.5 miles of causeway (earthen fill). Where the remaining mile comes from, I can only guess. Perhaps its 5 miles within the Mackinac Bridge Authority's jurisdiction?

To this day there are over 200 unanswered major technical concerns, no wind tunnel test has been performed, the bridge will be too low for the ships that are currently passing the Messina strait and so on. Also no rigorous tests of the ground has been done. AND the first stone of this madnesd has already been posed. In 2009, by Silvio Berlusconi (a mafia financer), before the project was cancelled for it's unfeasibilty. This is just round 2 of the clown show, and it will end in the same way: massive private profits and no bridge.

I'm Italian and I don't see the needing of such structures... Sicily and Calabria are two of the poorest region in the country. It's a money waste operation, made with public taxes and without any return in a foreseeable future. We should use that money to invest in our hospital or in our school system

@juandavidgiraldo518 10 дней назад

Thats a good pov, but the bridge could also be an opportunity for infrastructure investment openings, commercial investment facilities too, no need for ship transport anymore reducing the time of travel for products from both sides of Italy, increasing the economic growth of the island acquiring more resources for healthcare and scholarship investments.
