No not the film

BoJo is apparently keen on the idea of a bridge between Scotland and Northern Ireland.

It begs the question what the **** for?

Portpatrick to Larne is the suggested route:

The bridge, made of steel and concrete, would consist of two levels - one for cars and one for a railway.

Part of it could be a tunnel too, as a way of dealing with the offshore dumpsite Beaufort’s Dyke.

Unexploded World War Two bombs are believed to be one of the risks of the project, which lie near the dump.

An artificial island around 2.5 miles long and 500 yards wide is likely to link the bridge to the tunnel.

Under one version of Boris’ plan, the bridge would run from the Scottish coast over the trench, before becoming a tunnel for the final stretch to Northern Ireland.

Local geography might even dictate the need for two artificial islands to span the North Channel.

I get that BoJo is keen to be seen to be spending money on Scotland as a way of fending off cries for independence (best of luck with that), but given his previous track record on bridges and the general stupidity of the idea, I'm struggling to understand how the money (even on an initial assessment) couldn't be spent better elsewhere.

I hope it's a garden bridge,the last one in London enriched the lives of so many people.

As previously suggested on the main Boris thread

We should have three bridges

Ardrossan to Brodick

Arran to Campbelltown

Mull of Kintyre Lighthouse to Norn Iron.

Probably cheaper. Enough change left to build a wall up the middle of the English Channel. Probably.

Can’t see it ever being built for numerous reasons.

Long may it stay between England and me
It's a sure guarantee that some hour we'll be free

Well its not any dafter than having one. It avoids Beauforts Dyke and means the journey from Glasgow to Belfast would be a bit shorter.

But you still have to wonder what the point is (beyond bread and circuses). Bridges or tunnels are generally a good idea when you have a load of people on either side of a sea/ river/ mountain who need to get to the other side. I might be wrong but I don't see a huge pent up demand for moving people between Northern Ireland and Scotland.

That's before you consider potential border issues brought about be the Brexit settlement in NI.

This. General engineering opinion seems to be that this can't be done, even before such small issues as Irish railways using a different track gauge are taken into account.

The only demand from Belfast to Glasgow and vice versa is old firm fans, and I wouldnt wish them on the many good friends I have on Arran.

I'd much prefer a bridge from southerness across to Silloth, now yer talking.

Hello, civil engineer here, born in Northern Ireland but happily escaped (by ferry).

Bridge is probably unfeasible because of water depth - imagine how you'd engineer each pier.

This bridge is a political dead cat. Brexit has disgruntled the Unionists given their treatment by the scumbag Torys. A referendum on a United Ireland creeps closer due to Brexit, population demographics, the precedents set in Scotland, and even the recent success of Sinn Fein.

The proposed bridge is a tool for placating unionists on the island of Ireland. Side benefit is that it gives the Tories something upbeat to talk about while they fail the UK.

Bridge is probably unfeasible because of water depth – imagine how you’d engineer each pier.

Looking at oil production facilities it might be possible to implement each pier in the same way - look at the Draugen oil platform for example. You'd need to protect against accidental damage from shipping but again the oil industry have already solved this problem - the Hibernia platform can withstand contact with a six million ton lump of ice. The thing is, they cost. Lots. And even with say 1km span between piers you'd need thirty or so to make up the bridge. I'm assuming that the sea floor (apart from the Beaufort's Dyke bit) is suitable to take several 200,000 tonne structures.

Other than that it's either a distraction tactic from Cummings and Johnson or just one of the regular infrastructure reviews that occupy the time of various government departments.

A few moments thought suggest there is no way this is financially workable. After all the channel tunnel was a boderline case when it connects a market of 60M and 300M. So why anyone thinks a bridge/tunnel which is technically more difficult due to water depth but only connects markets of 5M and 3M is worth the cost beggars belief.

Cost £20Bn? Make that £30Bn at least after cost overruns and inflation. In 2014 the Scotland - NI ferries carried 400'000 vehicles.

https://www.transport.gov.scot/publication/scottish-transport-statistics-no-34-2015-edition/j415388-12/

Say the bridge increases that by 150% to 1 million. If you borrow £30Bn at 5% to build it that is £1500 per vehicle using it. Economics of the madhouse.

I'm not sure much of the England to Dublin traffic would divert. It's 6 hours+ driving to get from Manchester to Port Patrick then NI to Dublin.

It would make far more sense to build a canal suitable for naval vessels along the Scotland/England border.

And of course, a wall.

The official price tag for HS2 was set out in the 2015 budget and came in at just under £56bn.

However, the government estimate for the project has since almost doubled with the latest figure rising to £106bn - according to an official review leaked to the Financial Times in January 2020.

If you borrow £30Bn at 5%

Add a 0.

I can’t talk about the idiocy of this idea and the cretin that Blojo is, without breaking the swear filter into very small pieces and subsequently getting banned.

All I can say is that he knows it won’t happen, we know it won’t happen. It’s all to take up column inches and minutes on the news as a distraction piece.

It's unionist tub thumping keep the union together bollocks.

There's no demand, hence the reason there used to be 4 ferries crossing the channel from here to norn iron, now there's one.

There was some idiot on radio Scotia this morning wanting a tunnel from Kintyre, and 120 miles of railway, featuring a bridge over loch awe, to Glasgow. He was serious as well.

Used to work as chief engineer on the ferries from Larne to cairnryan, you'd be surprised how much freight is being moved there. It's a pleasant route, but when you look at all the infrastructure required and the current reliability of the service, a freight only bridge would be a huge advantage.

Not sure about the politics but looking at this from a technical perspective it should be totally feasible. Look at the Troll B oil and gas platform in the North Sea. Standing in 300m water depth so don’t see why a bridge would not be technically feasible.

Of course the expense is an issue but infrastructure projects like this are there for many years so costs can be amortised over many decades, so though the numbers are Eye watering my big, they are affordable. And the point of big infrastructure projects is they always stimulate the traffic and demand and trade and tourism between Scotland and NI will almost definitely be boosted and increase to the benefit of both countries.

I’m not sure it’s such a ridiculous proposition no matter how politically driven and cynical the intentions and timings of BoJo’s suggestion of it.

In a post brexit world wether you agree with brexit or not we have to make a success of it and have to think differently and be more bold and ambitious. I’d be surprised if a project such as this would be a ‘disaster’. what would China do? By now in China this project would have already been approved and construction started in all likelihood. It’s a bit of a ‘build it and they will come’ thing.

I'd actually be interested to know where the ferry traffic from Troon went. There was (still is but full of Irish timber destined for the sawmill across the road) a P&O cargo terminal and before that a Seacat before the services were scrapped. Dunno if the extra sea miles were the problem or something else.

But yeah, bridge is bonkers, usual pish.

Probably the same breed of nutter that thinks a bridge to Cumbrae is a good idea. They're everywhere.

Is the idea any more stupid than the bridge connecting Sweden with Denmark?

I was thinking on my ride to work this morning that a semi—submerged tunnel might work better - basically build a tube in sections that floats 100m below the surface - well away from passing ships etc but without the challenge of building 1000ft? bridge piers. As long as the design has the right natural buoyancy the main engineering challenge would be how to anchor the tube to the seabed enough to stop tidal movement.

If this would work all of the sections could be pre-fabbed, floated to site and then partially submerged - a bit like with the recent Tyne tunnel but not resting on the seabed.

Its 4 and half hours from Glasgow to Belfast in terms of road and ferry combined

Glasgow to Campbelltown and Torr to Belfast ... without time on a bridge in between is 5 hours.

I take it the quoted costs (guesses) for the bridge don't include upgrading the A76 and A77 to dual carriageway to cope with a doubling or trebling of traffic. So another few billion there. Chickenfeed.

Using the BoJo Garden Bridge Bridge Calculator (366m £53000000) not building the bridge would cost £6996000000 with the added bonus of no maintenance and retaining jobs on the ferry service.

Floating structures are fairly commonplace. The problem would be most of them are engineered for ~50 year lifespans, bridge foundations tend to be a bit more permanent.

Simple, just create an exclusion zone.

Works for everything from fiber optic cables, wind farms, firing ranges, shipping lanes, oil and gas platforms, munitions dumps, war graves, and those bits of the coast where burial at sea is allowed*.

*yes there are designated areas where you're allowed to dump a body where the tide shouldn't wash it up on a beach and the trawlers won't get it.
