Blackwall Tunnel Southbound Route To Close For Four More Weekends
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
Part of the Blackwall Tunnel will close this weekend as work continues on the Silvertown Tunnel.
These three paragraphs detail the closures.
The southbound route will be closed from 00:01 BST Saturday until 05:00 Monday and on three further weekends.
The 57-year-old crossing is also due to shut on 1-3 June, 8-10 June and 29 June-1 July, as resurfacing and landscaping work is undertaken.
The Silvertown Tunnel is due to open in 2025, after which drivers using both tunnels will pay to cross the Thames.
At least the works to create the Silvertown Tunnel, seem to be progressing as planned.
But then London’s tunnels have generally been completed on time.
First Look Inside £2.2bn Silvertown Tunnel
The title of this post, is the same as that of this article on the BBC.
These are the first five paragraphs.
For the first time, Transport for London has invited journalists inside what is one of the most controversial infrastructure projects in the capital.
The Silvertown Tunnel is 1.4km (just under one mile) long and stretches from Silvertown in Newham to the Greenwich Peninsula.
Inside the tunnel, it is extremely wide. A lot bigger than other tunnels like the supersewer or Crossrail. Boring was finished a few weeks ago.
Transport for London (TfL) says the scheme will address queues at the Blackwall Tunnel and reduce pollution. But it has faced fierce opposition from those who think it will do the total opposite and increase pollution and congestion.
And the big question is – even with mitigation – can a road tunnel ever be green?
Note.
- There is a good picture, showing the width of the tunnel.
- It is very wide and can’t be much narrower than the four-lane Queensway Tunnel, which was opened under Mersey in 1934.
These are my thoughts.
I Am Against The Tunnel Being Built
My main reason I am against the Silvertown Tunnel is that Transport for London’s mathematical modelling of and rerouting of buses past my house has been some of the worst I’ve seen. I talk about the bus problems I now have in Is The Nightmare On The Buses Going To Get Worse?
So until the two tunnels; Blackwall and Silvertown are complete and open with tolling, I won’t trust any of Transport for London’s pronouncements.
I also feel that as the Silvertown Tunnel will allow trucks to pass though, there will be times, when they will cut through the East End to get to the Motorways going North.
But now, it’s more or less finished, we will probably need to use it.
How Is The Tunnel Being Paid For?
The Wikipedia entry for the Silvertown Tunnel has a section called Costs, where this is said.
In 2012, the cost was stated to be £600m. A consultation in 2015 stated that the cost of construction was estimated to be £1bn. In March 2020, the cost was increased again, to £1.2 billion. Operation, maintenance and financial costs of the tunnel over 25 years is expected to cost another £1bn.
The £2.2 billion will be repaid by tolls on both tunnels. Effectively, it’s a Private Finance Initiative or PFI.
Can A Road Tunnel Ever Be Green?
This is the question the BBC asked in the last paragraph of my extract.
Although, I am very much against this tunnel, I do believe this tunnel can be green.
- Suppose, the tunnels were made free for zero-carbon vehicles, that were powered by batteries, hydrogen or possibly ammonia.
- This might nudge vehicle owners and operations to go zero-carbon.
This extra number of zero-carbon vehicles would help to clean up London’s air.
I wonder which will be the preferred route for trucks associated with construction to go to and from sites in Central London?
- These trucks are major polluters in Central London.
- There are sensible moves to make construction sites zero-carbon.
If the Silvertown Tunnel didn’t have tolls for zero-carbon trucks, then surely this would nudge, this sizeable group of trucks to go zero-carbon to the benefit of everyone in Central London.
The only problem with making zero-carbon vehicles toll-free, is that it probably ruins the finances of the tunnels, from the point of view of the investors.
Conclusion
I can see lots of conflict starting over the operation of this tunnel.
Superloop -February 2024
This article on the Londonist, shows the latest status of the Superloop on this TfL map.
Note.
- The recently opened; SL3 has a lot of stops including Abbey Wood on the Elizabeth Line.
- SL4 will go through the Silvertown Tunnel.
- Since it opened, I’ve never needed to use a Superloop route going about my daily business.
I have this feeling, that a couple of years after it fully opens, there will be a few modifications to the route.
How Not To Organise A Piss-Up In A Brewery
This afternoon, I wanted to get some lunch and buy my food for the weekend.
I live close to the junction of Southgate Road, Mildmay Park and the Balls Pond Road.
From the four bus stops there, I can get buses to the stopping centres of Angel, Dalston Kingsland, Hackney Central and Moorgate.
But not today, as all the bus stops had been closed!
As my leg was playing up, there was no way, I could have walked to the next stop.
In the end I created a fuss and a kind driver let me on a 141 bus to get to Moorgate.
Coming back, I got another 141 bus, which got stuck in the traffic jam, that the part-closure of the junction was creating.
Note.
- The 141 bus took five minutes to pass through the junction.
- Luckily, the driver was sensible and he let a lot of us out.
- As I live South of the Balls Pond Road, it was very convenient.
Obviously, the driver knew more about customer service, that the idiots who organised this megashambles.
I have a few thoughts.
Where Was The Publicity?
I use the 141 bus most days and I didn’t see anything at the bus stops and didn’t get any leaflets through the door.
The Traffic Lights At Southgate And Balls Pond Roads Are Unreliable
They were even worse, when I moved here and Transport for London replaced them a few years ago.
But they seem to have got more unreliable.
Where is John Cleese to give them a good thrashing?
The Silvertown Tunnel Effect
Consider.
- I asked a regular delivery driver, what is the gossip about the Silvertown Tunnel and he felt that it will gum up East London.
- This is my feeling, as before my stroke, I had driven all over the East End trying to save time and knew it well.
- I also feel, that a lot of heavy traffic will end up on the Balls Pond Road, trying to get to and from the M1 and A1, especially, when the Dartford Crossing is closed.
I am fairly certain, that at certain times the junction at Southgate Road, Mildmay Park and the Balls Pond Road is going to get very congested.
The Non-Availability Of Taxis
One of the reasons, I chose to live where I do, is that I am just off the route which taxis use to go back to Liverpool Street station.
But the number of taxis in the area has decreased substantially in the last few years.
- Islington’s Low Traffic Neighbourhoods are scaring taxis away.
- Many drivers are giving up.
- Taxis are expensive.
Consequently, I rarely use a taxi. I never saw one today, when it was needed.
The Junction Is Busy For Pedestrians
Crossing the junction is dangerous, as cyclists only consider the lights optional.
If I’d had a pound for every time, I’d nearly been hit by a cyclist or car on this junction, I could pay for a year’s electricity.
Mildmay Park Station
The area used to have its own station at Mildmay Park about 120 metres to the North of the junction.
This Google Map shows the site of the station.
Note.
- The railway is the North London Line.
- Highbury & Islington station is to the West.
- Dalston Kingsland station is to the East.
Mildmay Park station is marked by the blue arrow on the bridge over the railway.
It would be a very handy Coming-Home station, as its downhill all the way, from the station to my house.
Conclusion
Reopening Mildmay Park station would be good for the price of my house, by I doubt that anything will be done.
Sadiq Khan ‘Is Waging War On Motorists To Plug The £15 Billion Blackhole In TfL Finances’
The title of this post, is the same as that of this article on London Loves Business.
These are the first three paragraphs.
Sadiq Khan plans to raise at least £123 million per year by charging motorists to drive through the Blackwall and Silvertown tunnels.
In a written response to a question from City Hall Conservatives, the Mayor said tolls would be introduced on both tunnels when the new Silvertown Tunnel opens in 2025.
The Mayor said Transport for London (TfL) would receive revenue from the new tolls and penalty notices, less the cost of annual construction repayments and maintenance fees. The Mayor, who is chairman of TfL, has previously said he expects tolls and penalties to ‘more than cover’ these annual costs.
I don’t drive, so the cost of using the tunnels, has no effect on my finances.
This document from TfL says this about car usage in London.
London residents aged 16+ make 4.6m car driver trips and 1.4m car passenger trips
on an average day, of which 3.7m are within London, with the remainder involving
travel to and from London. Non-residents make around 1 million car journeys a day
to, from or within London.
It does look that London has a lot of car drivers and passengers.
Surely, out of common decency, the toll for using the Blackwall and Silvertown tunnels, should be disclosed by Sadiq Khan before the London Mayor Election later this year.
Or is he frightened, that the size of the toll will lose him votes?
Silvertown Tunnel: Cracks In Mayoral Policies
The title of this post is the same as that of this article on the BBC.
This is the sub-heading.
It is an infrastructure project that is well-underway with the boring almost completed — but it has a very low profile.
These are the first three paragraphs.
Every step of the Crossrail tunnelling, the media were invited along. Not so with this project.
This is Silvertown Tunnel. It is more than 1km long and will be London’s first road tunnel in over 30 years.
Perhaps one of the reasons it isn’t being pushed publicity-wise, is it is very controversial.
Tom Edwards gives a detailed outline of why the tunnel is controversial.
Under a heading of HGVs Using Bus Lanes, this is said.
Instead of using the Dartford Crossing, larger HGVs will be able to use the tunnel — and its bus lane.
Campaigners said that will mean more HGVs going through Newham and Greenwich.
I’ve also never heard this before.
Sheila Keeble, of the Greenwich Society, said the tunnel “will be magnet for bigger traffic than we’ve got at the moment”.
“One of the issues we have is all the developers are now looking at building distribution centres,” she said.
“At the moment the Blackwall Tunnel protects us from bigger traffic… Silvertown won’t.”
That is all very logical and I suspect we’ll see larger trucks in Hackney and Waltham Forest too!
There was also this bit of nonsense from Transport for London.
TfL says the tunnel will lead to an overall improvement in air quality.
How will all those trucks through the two tunnels reduce pollution?
In 2024, London must vote for a Mayor, who understands hydrogen, mathematics and science!
Should Hydrogen-Powered Trucks Pay A Lower Charge In The Silvertown And Blackwall Tunnels?
London has a lot of heavy diesel trucks, which include.
Cement mixer trucks.
Large eight-wheeler trucks transporting aggregate, building materials and construction spoil to and from construction sites.
Council refuse trucks.
Skip trucks.
Supermarket delivery trucks.
They are large polluters and the only way they will be made zero-carbon, will be to use hydrogen.
In Cummins Agrees To Integrate Its Hydrogen ICE Technology Into Terex® Advance Trucks, I write about how Cummins and Terex are going to be building hydrogen-powered cement mixers.
This picture shows the baby of the range, which could be ideal for a smaller country like the UK.
Note how it is the other way round to traditional cement mixer trucks.
As companies are now selling low-carbon concrete in the UK, I suspect, it won’t be long before they will be delivering it in a hydrogen-powered zero-carbon truck.
If hydrogen-powered trucks could be given an economic boost, by lowering their charges for the Silvertown And Blackwall Tunnels, this might increase their uptake by owners of large trucks, which would in turn reduce pollution.
But this would need the election of a London Mayor, who had a hydrogen policy other than ignore it and hope it goes away.
Blackwall And Silvertown Tunnels: Mayor Proposes Discount For Some Users
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
The London mayor has written to the government to say he is considering a low-income residents’ discount for the Blackwall and Silvertown tunnels.
These paragraphs outline the story.
Both east London tunnels will have tolls from 2025, although no specific charge has been decided.
Sadiq Khan said the impact on Londoners who might struggle to afford the fees needed to be mitigated.
Mr Khan has asked that any discounts should not affect funding for Transport for London (TfL).
itvX has an article with this title Drivers Could Be Charged £5.25 To Use Blackwall And Silvertown Tunnels, Sadiq Khan Suggests.
My view is that the phrase about a pig and lipstick applies to the Silvertown Tunnel.
Silvertown Tunnel Works – 24th September 2023
I took these pictures of the Silvertown Tunnel works on the North Bank of the Thames today.
I was on a train going to Woolwich Arsenal.
What Is The Silvertown Tunnel?
The title of this section, is the same as that of this article on the Londonist, which is an excellent description of the Silvertown Tunnel.
The article says this about tolls.
The new tunnel will require you to part with some pounds if you want to use it. Despite the consultation on this taking place a decade ago, the final details have yet to be publicised. We can expect something similar to the Dartford Crossing (currently £2.50 for cars etc, free for motorbikes/mopeds).
As there is a mayoral election next year, I doubt that Sadiq Khan will announce the charge on the Silvertown and Blackwall Tunnels before the election.
Let’s Play Accountants
This is a paragraph in the Londonist Article.
Construction of the tunnel is eating up something like £1.2 billion (2020 estimate). It’ll then cost another estimated £1 billion over 25 years to pay for maintenance, financing and operation. Riverlinx paid up-front costs and will be paid back by TfL through money collected from tolls.
The running costs would appear to be a billion over 25 years, which is £ 40,000,000 in a year.
This is said on this page on the Greater London Assembly web site.
Blackwall tunnels (northbound and southbound) each carry approximately 50,000 vehicles per day in only two lanes of traffic.
That means that each tunnel handles approximately 18,250,000 vehicles per year.
Dartford Crossing charges are according to the Wikipedia entry are as follows.
- Cars, motorhomes, small minibuses – £ 2.50
- 2-axle buses, coaches, vans, goods – £ 3.00
- Multi-axle goods, coaches – £ 6.00
The Wikipedia entry also says this about the capacity and traffic through and over the Dartford Crossing.
The design capacity is 135,000 vehicles per day, but in practice the crossing carries around 160,000.
My good friend; Bob from the 1970s had an impeccable cv.
- Chief Accountant of Vickers.
- Chief Management Accountant of Lloyds Bank.
He was also one of two outstanding practical accountants I have known.
Several of his practical tips on how to handle money in computers, ended up in Artemis; the project management computer system, I wrote in the 1970.
Bob and I would solve problems in Mother Bunches Wine Bar and I suspect, we’d come to the conclusion, that an average charge of £3 per vehicle will be charged in the Blackwall and Silvertown Tunnels.
I also believe from my fluid flow experience, that a proportion of the excess traffic through and over the Dartford Crossing will divert to the new Silvertown Tunnel.
- Together the Blackwall and Silvertown Tunnels will have four lanes in both directions.
- The Silvertown Tunnel will hopefully designed to modern standards and be more free-flowing, than the Blackwall.
- Sat-navs will direct drivers to the quickest routes.
Just as water finds its own level, an equilibrium will develop between the flows.
- I suspect that during the day, the flow over the Dartford Crossing will drop to the design capacity of 135,000
- At night, will vehicles divert through the free-flowing Blackwall and Silvertown Tunnels?
- Will those living in North Central London inside the North Circular Road drive through the Blackwall and Silvertown Tunnels?
- Will the free-flowing Blackwall and Silvertown Tunnels encourage people crossing the Thames to use their car, rather than the train, as the car is more convenient and the toll will be less than the train fare?
- We should also beware that new roads, railways and tunnels generate new traffic, that no-one predicts.
My feeling is that combined traffic through the four lanes of the Blackwall and Silvertown Tunnels will be upwards of seventy thousand per day.
I can now calculate revenue for different levels of combined traffic through the Blackwall and Silvertown Tunnels.
- 40,000 vehicles in each direction per day is a total of 29,200,000 vehicles per year, which would raise £ 87.6 million per year in toll charges.
- 50,000 vehicles in each direction per day is a total of 36,500,000 vehicles per year, which would raise £ 109.5 million per year in toll charges.
- 60,000 vehicles in each direction per day is a total of 43,800,000 vehicles per year, which would raise £ 131.4 million per year in toll charges.
- 70,000 vehicles in each direction per day is a total of 51,100,000 vehicles per year, which would raise £ 153.3 million per year in toll charges.
- 80,000 vehicles in each direction per day is a total of 58.400,000 vehicles per year, which would raise £ 175.2 million per year in toll charges.
I am assuming the following.
- All days of a 365-day year have similar traffic.
- Everybody pays without fuss, by technology like number-plate recognition.
- The average toll chare paid is £ 3.
I am drawn to the conclusion, that the contract signed between Transport for London and Riverlinx, is a licence to print money.
Even, if the tunnels only attract 40-50,000 vehicles per day, the revenue is way in excess of the £40 million needed for maintenance, financing and operation of the Silvertown Tunnel.
I have a few further thoughts and questions.
Who Are Riverlinx?
This is said on the About Roverlinx page of the Riverlinx web site.
TfL awarded Riverlinx SPV (Special Purpose Vehicle) the contract for financing and overseeing the design, build and maintenance of the Silvertown Tunnel in 2019.
The Riverlinx CJV (Construction Joint Venture) is contracted by TfL and Riverlinx SPV to complete the design and construction works, delivering the Silvertown Tunnel on time and on budget.
Riverlinx CJV is a joint venture, a partnership bringing together international, market leading expertise from three civil engineering and construction companies: BAM Nuttall, Ferrovial Construction and SK ecoplant.
In collaboration with TfL, our supply chain and other key stakeholders in the project, Riverlinx CJV will complete construction of the Silvertown Tunnel in Spring 2025.
Note.
- BAM Nuttall is a construction and civil engineering company, that is a subsidiary of the Dutch Royal BAM Group.
- Ferrovial Construction is the construction subsidiary of Spanish company; Ferrovial.
- SK ecoplant is a subsidiary of the South Korean conglomorate; SK Group.
These companies should be capable of building the Silvertown Tunnel.
Where Will The Money To Build The Tunnel Come From?
In World’s Largest Wind Farm Attracts Huge Backing From Insurance Giant, using an article in The Times, I explain how Aviva invest our pensions and insurance money in wind farms.
Strangely, a tolled tunnel is a bit like a wind farm financially, in that if it’s working and the wind is blowing or the traffic is coming, it will continue to generate an income.
Built by quality construction companies, as most tunnels are, they will be the sort of investment, that would satisfy the Avivas of this world.
Will Riverlinx Get All The Tolls From The Tunnel?
Nothing is said about how the excess of income over expenditure will go.
I suspect, as the project is being designed, financed and built by Riverlinx, that they will not go unrewarded.
Will The Mayor Set The Toll Charges?
I suspect that the Mayor and TfL will set the charges.
These are some figures with different charges for 70,000 vehicles in each direction per day or a total of 51,100,000 vehicles per year.
- £3 in each direction would raise £ 153.3 million per year in toll charges.
- £4 in each direction would raise £ 204.4 million per year in toll charges.
- £5 in each direction would raise £ 255.5 million per year in toll charges.
- £6 in each direction would raise £ 306.6 million per year in toll charges.
Note.
- Some of the papers are talking of a four pound charge.
- A pound increase may not be much to the average driver, but they will certainly mount up.
Higher toll charges could be used by an unscrupulous Mayor to deter vehicles entering Central London or nudge people towards public transport.
What Happens If The Tunnel Springs A Leak?
I can remember the following tunnels being built under the Thames in my lifetime.
- Blackwall Tunnel – second bore
- Dartford Tunnel
- DLR to Greenwich and Lewisham
- DLR to Woolwich
- Elizabeth Line to Woolwich
- Jubilee Line – four crossings
- Victoria Line to Vauxhall
None of these seven seems to have sprung a leak recently. And neither have the older Victorian tunnels.
Tunnels with an income stream, appear to be a good risk, if they don’t spring a leak.
But London tunnels don’t seem to have a high likelihood of leaking.
Fines
Fines could be a problem, but this article on Kent Online, which is entitled Dartford Crossing Continues To Generate more Than One-Third Of Income From Fines As Profits Total More Than £100m, says otherwise.
Conclusion
This would appear to be a low risk venture and I suspect it will make Riverlinx and TfL a lot of money.
Traffic Constipation At The Angel
On Tuesday, I went to the Angel, with the intention of doing some shopping and then got tuck in an enormous traffic jam.
Note.
- In the end I abandoned the bus and walked.
- It looked like it was all caused by emergency roadworks at the Angel.
- These happen regularly, as Islington’s water pipes aren’t the best quality.
I believe traffic jams at the Angel will get worse, when the Silvertown Tunnel opens, as this will encourage trucks to take routes through Central London, when the Dartford Crossing is busy.
