Norway’s $47BN Coastal Highway | The B1M

Norway’s $47BN Coastal Highway | The B1M

The western coast of Norway is home to some
of the most dramatic landscapes on earth. Carved by glaciers throughout the ages, some
of these fjords stretch for 200 kilometres inland and are over a kilometre deep. The current convoluted travel route through
and around this terrain takes you along Norway’s 1,100 kilometre, 683 mile, E39 highway. A road with a total journey time of 21 hours. Now, the Norwegian government are working
to improve access to services and residential and labour markets across the country’s
western regions by embarking on the largest infrastructure project in the nation’s history. Norway’s E39 highway runs between, Kristiansand in the far south of the country and Trondheim
in the north. The route navigates its way across the fjord network and features no fewer
than seven ferry crossings. The new coastal highway project aims to eliminate
the need for ferry services altogether by building a series of bridges and tunnels across,
through and under the landscape. With many of the fjords along the route being
too wide or too deep for conventional infrastructure to cross, innovative new solutions are being investigated by the Norwegian Public Roads Administration. Rogfast is the first in a series of crossings
that will link the E39, connecting Stavanger and Haugesund via a 27 kilometre, 16 mile,
under sea tunnel. This structure will reach depths of up to
390 metres below sea level, making it the deepest as well as the longest undersea road
tunnel in the world. The Rogfast project will in fact consist of
two tunnels connected every 250 metres with emergency exits. Each tunnel will have a lay-by
at 500 metre intervals, along with telephone and surveillance cameras along the route. The tunnel will also feature a mid-route intersection
with the island municipality of Kvitsøy creating an undersea tunnel junction and connecting
the island with the Norwegian mainland. With work begun in 2018, this element of the
project is set to be completed by 2026 at a cost of USD $2BN. While the Rogfast works are already underway,
the scale of some other fjords is presenting the project team with extreme engineering
challenges. Bjornafjord – located to the south of Bergen
– stands 5 kilometres wide, and reaches depths of 600 metres. To cross this challenging stretch of water,
a proposal has been put forward for a floating bridge, anchored to the shore at both ends. The Sulafjord crossing has seen two possible
solutions put forward. The first is for a three tower suspension
bridge, with two of the bridges’ towers anchored on land and the third central tower
anchored to the seafloor, some 400 metres below the water line. An alternative proposal for a “submerged
floating tunnel” would see two interconnected tubes running side by side tethered to the
seabed using high strength cables. Crossing the Romsdalsfjord will require a
16 kilometre undersea tunnel, much like the Rogfast project, from Alesund to Midsund – followed
by a 2 kilometre suspension bridge connecting onto Molde. By far the most complex and ambitious of all
of the coastal highway crossings is that at Sognefjord – also known as the “King of
the Fjords”. Norway’s largest and deepest fjord is over
3.7 kilometres wide and an incredible 1.3 kilometres deep at its lowest point. While these extreme distances pose their own
challenges, engineers must also account for the high number of ships that enter the fjord
on a regular basis. Any crossing must allow for a clear shipping
lane that is at least 400 metres wide – with 70 metres clearance above the water’s surface
and at least 20 metres clearance into the depths. To deliver this, the project team are considering
numerous different types of crossing for this fjord. The first is a traditional suspension bridge.
With a 3,700 metre crossing, such a structure would be almost double the length of the world’s
current longest bridge and would require support towers at least 450 metres tall, significantly
eclipsing the 343m tall Millau Viaduct in France to become the world’s tallest bridge
structure. A floating bridge is also being considered.
However, this structure would need to raise to allow ships to pass and achieving such
a feature in a bridge that is only anchored to each shoreline poses considerable engineering
challenges that are yet to be overcome. In a similar proposal to that found at Sulafjord,
a submerged floating tunnel in also being considered. This proposal would differ slightly to its
counterpart due to the extreme depth of the Sognefjord. Rather than being tethered to
the seabed, the tunnels would be suspended from floating pontoons that would allow ships
to pass overhead. A hybrid proposal is also being considered
– combining a floating pontoon bridge with a portion of submerged floating tunnel that
allows ships to pass. Whilst fixed bridges transferring into fixed
tunnels is not an uncommon solution in waterways with high shipping traffic – such as the link
between Denmark and Sweden and the extensive Hong Kong to Macau crossing – combining the
two floating structures in this way would create the world’s first example of such a
solution. Finally, a proposal for a multi-span cable
stayed bridge is under review. This structure would feature four floating pylons tethered to the sea floor rather like oil rigs. With safety and environmental considerations
being of the utmost importance, Norway’s vast coastal highway project is set to become
a new benchmark in engineering capabilities and a model for future infrastructure projects
around the world. If you enjoyed this video and would like to get more from the definitive video channel for construction, subscribe to the B1M.

  1. The idea of a submerged floating tunnel system is very intriguing. My concern is what happens if the tunnel walls are breached. If this technology could ever be made to work, it would be ideal for a possible future fixed link crossing between Vancouver Island and the Mainland in British Columbia, Canada.

  2. All the bridges are gonna ruin the scenery of these fjords. Combined with that and the cost, I don’t think they will happen.

  3. Actually signals were continously receiving by aliens to build such a way to peacefully land on the earth and interestingly norway is the gateway of anyone out of our earth needs to enter into our world.Wellcome the aliens the new cousiens of earthians.

  4. Sooner or later the small species enter into the earth via un explainable ways,the sewarage system of London witnessed the story and it was kept in secret by Uk Government

  5. USA cant afford clean water but can afford a 2 trillion dollar tax cut to the super rich that nobody asked for and nobody needed becoming immediate debt. Literally set cash on fire and got nothing.

  6. I can already see a terrorist attack under tunnels. Orchestrating a traffic break on both sides of the open entrances, causing heavy traffic inside the belly underwater tunnel. A blast inside would be catastrophic, filling the entire tunnel with water. Sad, but thats the world we live in.

  7. Norway has 47B for placing pipes for cars in the ocean.. but needs USA to defend it.. trump is right when he claims europeans are spending less on defense

  8. Wonderful. but you won't see my aristocratic backside motoring through the entrails of that labrinthinan arterial enterprise, I'd need qualudes and a child seat.

  9. Absolutely AMAZING!!! ITs really incredible what people can achieve when they come together! And to think…we waste so much time, money and lives on designing ways to kill each other (war of course). What would happen if we spent all that time and money teaching each other how to get along?! The sky would literally be the limit! And NO…im no peace-nik! Just sharing my thoughts, GREAT VID!

  10. Norway, the country that makes is 90% of its PIB from oil export …feeding petrol engines in other countries! WHAT AN HYPOCRITE BUNCH OF WORLD POLLUTERS !

  11. Started in 2015 it should be finished in 2027. 1100km road with tunnels, wast bridges and good infrastructure.
    Meenwhile in Russian Far East our government started to build 146km road in 2013 and they said it will finished in 2022. But now we have the end of 2019 and only one section(18km) is finished…. And assurance that it will fully finished in 2030.
    So, who will be faster? XD

  12. And the Victorian government in Australia can't build a highway from the city centre to our major airport – less than 25 kilometres. Oh dear.

  13. Just to be pedantic. The Kilometre comes from two parts. Kilo(Kee/low) meaning one thousand. Ok…still with me here? Good. The second part, metre(mee/ter) denoting a unit of measurement. Hence Kilometre meaning one thousand metres. I do not know of this Kalometer of which you speak. This pronunciation is completely incorrect and creeping into everyday speech. Would you say this word: centimetre as Sontometer? Or do you weigh a certain number of Kologrems? No. You say centi/meter and kilo/gram. Why the hell would you then say Kalometer? This is totally wrong and I will point this out until everybody gets with the program. Even sat Nav systems use your stupid pronunciation and it is completely incorrect. Lift your game B1M. I expect better from a scientific channel.

  14. Nice plans, but make sure that Joseph Jeffrey Hazelwood is not permitted to pilot anything floating in the region.

  15. Why should anyone subscribe to a group of people making money from things we could find on Google. They should do something creative and original, but they CAN'T… Poor guys.

  16. I saw some people asking, but couldn´t find the comments so here is the answer to those questions:

    We don´t have earthquakes in Norway. I don´t know how to explain it in English, but I know that we do actually have them, they´re just so, so small we can´t feel them and they don´t affect us at all. So now you know that wouldn´t be a problem considering this whole thing

  17. If this is actually built there will be a lot of people killed on it due to faulty construction of some sort.

  18. The feat of this project won’t be the engineering, it will be how they are going to build it for $2 billion U.S.
    I’m guessing it will be at least 3x that amount.

  19. when thinking about ships crashing into stuff and seeing this tunnels i'm really feeling kinda bad. i mean of course they would think about this stuff but most the structures didn't seem to handle this problem

  20. The UK are spending £30billion on HS2 a rail project that is a fraction of this, being built on land. #UKCorruptionisexpensive

  21. I am so amazed by the ingenuity and engineering of this massive project.
    I hope and pray that this comes to engineering marvel that the rest of the world will follow.
    Thanks for sharing.

  22. From the video – 2.25 – – If they cannot place the emergency telephones on the same side of the road as the emergency vehicle lay-bys, then I see little future in the Norwegians getting their arses into gear planning the huge structural complexities that lay ahead.

  23. Looks unnecessary and what about the environment? Do we really want to build something on every square meter of this planet?

  24. Everybody likes infrastructure, but this screams boss-level boondoggle that makes Boston's Big Dig look like an HO slot car track. Given the population density of the country, the cost per capita must be as welcome as a plate of month-old lutefisk (okay, they might actually be better after a month). And that's just the (ho-ho-ho) "budgeted" cost. No way that this could come in over budget.

  25. I thought this was click bait when i saw the heading. Staggering feat of engineering and planning if it can be completed.

  26. None of these ideas or future construction can be called a world first, China has brought of these different idea into reality into the world years back, check out the newly finished Hongkong-zhuhai-macau bridge.

  27. this tunnel, billions for the mars projects and hyperloops, megacities in arabic countries and china – how much is the world? that reminds me of the last days of babylon. By 2025, NONE of these projects will be finished.
