[@alexguest9937]

The A75 is the road which links Dumfries to Stranraer, and the road to Portpatrick splits off this shortly before the A75 gets to Stranraer. The A75 is mostly SINGLE carriageway (one lane each way) so the whole of that lot - some 75 miles of it - would require dual-carriageway upgrade, along with the bypassing of Crocketford and Springholm, two villages which the road currently goes straight through. Even now the A75 is constantly being completely CLOSED for periods of time for maintenance, isolating Stranraer and the ferry port at Cairnryan from the rest of the UK to the east and south. You should see the amount of artic' lorries that use these ferries, and the A75, going between the UK and Ireland! In addition to that the train line from Dumfries to Stranraer which used to operate was shut and dismantled in the 1950s due to Mr Beechings wonderful cuts. So if the bridge was to operate a train service that would all need to be put back into place (the same 75 mile length). Not that these infrastructure projects are necessarily unwanted in the area, indeed there is a petition you can sign to help bring back the Dumfries - Stranraer line. Most people want that (I would say) along with the upgrading of the A75 to dual carriage status. The point is that to connect the bridge to the rest of southern UK (ie England) these infrastructure projects would HAVE to be put in place as well, therefore adding significantly to the cost of the bridge/tunnel itself. As a denizen of Stranraer myself, I would guess that this is one of the main reasons why, when Boris Johnson was 'injected with a shot of reality' he dropped the project so swiftly and completely; because it brought into stark focus the relatively impoverished state of the infrastructure of the Galloway area. And the need to fix these issues BEFORE even contemplating the bridge. And he didn't even think to look at the lack of infrastructure either side of the proposed bridge before he went and spent all the money on the feasibility study. A simple look on google earth would have shown him. Utter f*ckwh*t.

[@KevOSMusic]

Having done the crossing fairly recently, I was surprised at the A75 & the quality of it. (driving from England to Belfast). Honestly, I just can't understand Unionism at this stage. If there was a proper Unionist attitude in Westminster, they'd be actively working on improving interconnectivity across the UK. That route has so much potential without a bridge/tunnel but the infrastructure is not there to support it.

[@jedsithor]

I think the best chance of a bridge or tunnel happening is if it's between the Ireland and Wales and if it's a joint UK/EU project. While it would be longer than either of the proposed sites between Northern Ireland and Scotland, if we put aside the costs of building it and the various construction and upkeep issues and look only at future utility, I think it makes more sense to go from the relative middle of one island to the relative middle of the other. If you're driving from London in the UK or Cork in Ireland, driving to Wicklow or Wales respectively is going to be preferable to driving to Antrim/Scotland to cross over. The main reason to connect Northern Ireland to Scotland seems to be political, in order to create a direct link between Northern Ireland and Britain. While it would be the shortest route between the islands, it wouldn't be the most convenient for the majority on both islands. It's also possible that by the time the project is finished, the political situation of Northern Ireland and the UK may have changed. 30 years from now, Scotland might not be part of the UK and Northern Ireland might not exist. It's entirely possible that a bridge between Northern Ireland and Scotland could end up being a project funded by the UK to connect two pieces of land that end up not being part of the UK by the time it's finished.

[@kevadu]

There's an alternative to a conventional floating bridge that might actually work: a floating submerged tunnel. Basically the idea is you can still have pontoons on the surface providing flotation but they're being used to suspend an underwater immersed tunnel. The underwater tunnel would be deep enough to avoid most weather conditions (and ship traffic) but unlike a conventional immersed tunnel it doesn't have to lie on the actual sea floor. That can be very helpful in deep water. To be sure, such a thing has never actually been built before. But it's not a completely crazy idea, there have been many such proposals in the past and the idea seems theoretically sound. Immersed tunnels are fairly mature technology and this really just involved suspending underwater rather than having it lie on the sea floor. There was even a proposal to use this for a crossing to Ireland (as the picture at 14:37 kind of shows), but it's kind of a shame Simon didn't really talk about it.

To be fair, not everything he built stayed up. We have survivor bias, though most of it did because he over-engineered the shit out of things. Hence their extreme cost. His instance of using a wider 7ft rail gauge on the GWR made things orders of magnitude more expensive to build than the standard gauge as you needed larger embankments, much longer curves and much larger bridges and tunnels, but it benefited us down the line (pun intended) when we moved to standard and now had a legitimate high speed rail network by default. At least high speed for the time. You can still see the size difference at somewhere like Paddington Station where they didn't reconfigure the platforms, and just have big gaps between them where the wider track once was. He also put holes in the struts holding up the roof to run cables and piping though for the future expansion of the station. You can see them if you look closely. They were never used though, but still there if they were needed.

There is equipment available now that can re-gauge railway vehicles’ axles while they’re on the move at a reasonable speed, 30-40mph. But only vehicles with adjustable gauge would be able to use the link. That excludes anything in use at the moment in either country. A cheaper(?) way would be to lay an extra running rail between the existing rails in Ireland, and just outside them in GB. But; the gauge difference is possibly too small to leave room for another rail, as it would be very close to an existing rail in each country. Or perhaps new dual rails could replace an existing one. But for what distance, and where to?

[@TalesOfWar]

@@MomMom4Cubs Most derailments in the US are because of extremely poor rail maintenance or because the haulers don't give a shit about following speed signals because they need to meet their deadline. The freight also destroys the tracks Amtrak use which often bows them, and Amtrak run faster trains so it multiplies the issue.

I also worked at sea so also aware of how the tides and currents are out there. Not the place to sit anything down and hope it's still there when you look back to secure it. There was already a heavily subsidised ferry route that ran C'town to Ballycastle operated by Argyll & Antrim Steam Packet company which were part of Seacat/Hoverspeed which in turn was owned by Seacontainers... A massive international company so not exactly lacking in money to throw at things. When the subsidies dryed up they pulled the route in a heartbeat because it was a money pit of a route... And that was with the MV Claymore which was 'sold' to steam packet from Cal Mac at an hilariously cut price. Even with all the financial help it never made any money. A massive draw back was always that drive down the A83. It's 130 miles from Glasgow and if you know the road, 3 to 3 1/2 hour drive. If you don't then 4 hours if you want to get to the end in one piece. There is also an entire section known as the Rest n Be Thankful that is prone to massive land slides and the alternative route when the Rest is blockedis even more "Fun". It's known as the Old Military Road. In winter if there's snow on the Military Road and the Rest gets blocked with a slide, then the peninsula basically becomes and island. I love my wee home Toon BUT the notion of having such a massive project like a bridge to NI jump off from there is nothing short of insane... Unless the objective is to burn a butt load of money, waste a lot of ppls time and ensure the A83 takes its place as the deadliest road in Britain which it could probably quite easily do if the traffic using it gets any busier.

For 'bridging' these large straits the building technique is not to built a bridge over the water nor a tunnel under the sea floor, but to built a buyant tube that floats in the water (40-50 m below sea level) and is firmly tied to the sea floor with cables. The design of that tube is a tube-in-a-tube design, between the inner and outer tubes buyoant material (like EPS) is used to keep it floating. The construction of such a floating tunnel can be done completely from land in 100m sections, and they are pushed through a digged trench on rollers into the water and then connected to the sea floor. First with temporal connections the tube can glide through and when finished with a permanent connection to the sea floor. Easier and cheaper to built then either a bridge or tunnel under the sea floor. Can be used in many places, but maybe not in waters where tsunami's occur.. If the water level is really shallow, instead of a buyoant tube one could use a tube built on an underwater bridge.

the North Channel figures are 100m to 300m deep at sea floor, you cannot build artificial islands in that depth of water. Plus the trench has over one million tons of military ordnance in it that was dumped between 1945 and 1958 so makes a tunnel impossible.@@abaddon1371

The main problem for any sort of bridge is the really, really rough Irish Sea.

Looking at the two terminal points for either type of crossing, they would be nowhere near the towns mentioned. There’s the not so small issue of the approach roads/rails at either end. These couldn’t just rise or descend just where the crossing starts. They’d have to start miles away! Rail vehicles couldn’t reliably manage more than a 1% (1 in 100) gradient; perhaps not even that, as too much speed may be lost over a long approach. Road vehicles could manage a stiffer gradient, but if it’s still too long, you’d end up with LGVs etc grinding along at walking pace in 1st gear! An example - there was a study to build a road and pedestrian bridge over the entrance to Portsmouth Harbour to link Gosport to Portsmouth; a tunnel is a big NO. Various groups, mostly in Gosport and beyond keep bringing it up. There is a passenger ferry, but no possibility of a vehicle one (insufficient space on each side). Takes 3-4 minutes. You can spit from one side to the other! For vehicles however, it’s a 16-17 mile circular route, which can (does!) take an age at peak times. 30 minutes at 3am on a Sunday if you’re really lucky! Anyway, the study found that the approaches to what would have to be a VERY high bridge (Naval vessels can be very tall) would have to start about 7-8 miles EAST of Gosport. It would culminate in an exceptionally tall viaduct hanging over the towns on the way, including Gosport and Portsmouth. Once the harbour entrance was cleared, the viaduct would begin its descent OVER Portsmouth, curving north, for about 8 miles, finally hitting ground level north of the Cosham area. The extra time required to get to and from both Portsmouth and Gosport from the approach ends would be more than the existing time needed! This Celtic Sea bridge would be at least as high if not higher. For the tunnel, at 100m depth minimum, you’d be looking at 10km/6-7 miles at each end for the approaches.

What we need is to extend the H3 on Oahu, Hawaii and make a bridge to Seattle or LA. Lol

[@ciaranbrk]

When they were both in the Eu yeah could see it but now doubtful. The two are very different I don’t think it would be a popular project in Ireland given how much trade has dropped off between the two. It’s more of a Unionist pipe dream to connect the two islands basically it’s like the Kerch bridge concept connecting Russia and Crimea for ever concept for the DUP.

[@markhughes7927]

It’s actually quite possible to conceive and also rapid and inexpensive to construct (barring government project oversight) using the combination of two little used construction techniques known as the syncopated-cubeoctahedron (aka khatmatrix) and the isotropic vector matrix - could probably usefully add a bit of ‘non-dom’ geodesy as well!

[@ZvonimirZelenika]

Though obvious solution isn't mentioned or obvious example compared - undersea rail tunnel on Galloway route would be comparable to Seikan tunnel (54km and 240m below surface, built 35 years ago). Irish Sea tunnel might be a bit longer and somewhat deeper but it wouldn't neither be longest nor deepest tunnel built (a bit northern routing would avoid the deepest part of Beaufort's Dyke). We can also all see how operations of Channel Tunnel work with high-speed, car/lorry shuttle and cargo trains so copying the same model here could be absolutely feasible (with some shuttle trains maybe operating Dumfries-to-Belfast route and some operating just the tunnel section). What is also comparable is that Hokkaido and Ireland (island) are very similar - 83.000-vs-84.000 square kilometres in surface with Ireland having bigger population (7-vs-5 million). In Hokkaido case, population centres are even further away on both sides then in case of Galloway route (with Belfast literally being on one of tunnel exits) and land between Dumfries and Stranraer is actually much easier to build the new railway line than it was to build high-speed line between (Shin-)Aomori and Seikan Tunnel. In general, it wouldn't be neither the deepest or longest tunnel built so far, so all technical challenges are solvable. What isn't solvable is that country that has given us railway and industrial revolution and has built Severn Tunnel in 1886 and Forth Bridge in 1890 is fully incapable of dreaming and building something at this scale today.

[@neilgwynne5158]

Completely agree. Civil engineer and I have been through the seikan tunnel. A tunnel under Beaufort dyke is feasible. Norwegian have be laying lots of really deep road tunnels It's not the engineering, it is finance and politics. Seeing as how the UK. Construction industry is stretched is this a priority...????

[@bk99911]

Only 23km of the 54km Seikan is actually under the sea. The rest of the tunnel is necessary to get to the depth to go under the sea. An Irish tunnel would end up being longer.

[@ZvonimirZelenika]

@@bk99911 Of course, it's underwater section would be comparable to Channel Tunnel (at nearly 40km), but my point is that Irish Sea tunnel would not be order of magnitude bigger project than anything but would be pretty comparable to what has been done (Seikan, Channel undersea tunnels and Gotthard, Cenis, Brenner in Alps). But it's interesting quirk that Ireland (island) and Hokkaido are actually pretty similar in size and population.

[@229andymon]

As someone who has driven the road to the end of the Kintyre Peninsula, I can assure you anyone proposing that bridge has never done so.

[@SpaceDogGlobalEntertainment]

Yeah same for Portpatrick, I mean yes there’s infrastructure but it’s infrastructure meant for a town of 600 people. The entire appeal of Portpatrick is it’s a charming and peaceful little coastal town, a bridge would ruin all of that, and there is no space there to build it either, at least without destroying things that the town relies on like the port. Anyone who thinks that bridge is a good idea has only ever seen Portpatrick on a map and has no idea how small it is.

[@jamez6398]

I like how there's tunnel on the seabed, under the seabed, or bridge, or tunnel somewhere between sea surface and sea bed.

[@jeffdroog]

Please stop using meth.Get some help.

[@Hession0Drasha]

You never know, better energy tech could allow for lazering tunnels through things, might make it a lot cheaper 🤟 If possible, the mail route would be the most economically beneficial. Dublin to manchester, would be a powerfull mix.

[@bhgtree]

Never is a long time.... As a Irish person, I would love to see this happen, the advantages so much outway the cost and technical problems. Thanks Simon.

[@NedNew]

Erm, do they? I fail to see many advantages? As an Irish person I would have no interest in seeing this happen. It would be obsolete anyway.

[@brianlawlor4221]

Eh what? As an Irish person I disagree hugely. They only starved millions of us to death but hey don't worry about it eh, wtf.
