PROJECT l Havnetunnel — København

[Hafnia]

The Harbour Tunnel
Sund & Bælt Partner has for Realdania, Copenhagen and Copenhagen Harbour conducted preliminary investigations of an harbour tunnel in Copenhagen.

The initial studies dealing with the possibility of combining a pacification of the City with the construction of a road link between North Harbour and Amager highway, east of downtown Copenhagen. In most of the line connection will be placed in tunnels under the Copenhagen harbor. The total length of the tunnels will be approx. 12 km.

The aim of the port tunnel is also to ensure access to development areas northeast and southeast of Copenhagen without burdening the existing road network further while reducing through traffic in downtown Copenhagen, which today passes Langebro and Knippelsbro.

Hope you guys thinks a thread about this subject has some relevance, even it's so far are on the theoritical plan.

Berlingske has an article in the daily one, about the pension company Sampension are willing to invest up to 10 billions dkr. in a Harbour tunnel, that has been discussed for many years.
The coorporation between a private and a public partnership (OPP) are something that will be more common the years ahead, especially in the bigger infrastructurel projects while the state having less money.

Build it now, or else.......

But why the detour around trekronerfortet, it could just turn south just around the text that says Nordhavn and save some 100 meters of tunneling.

Maybe to get a nice gentle curce - sharp turns are not that popular on highways?

Or maybe because of the coming 1 km. cruise ships quay.

I believe there were also 2 big problems with the REAL submerged harbour tunnel which resulted in the politicians deciding in favour of the East Amager solution.

1, There was not enough space between the supports of the 2 older bridges, Knippelsbro and Langebro.

2. the complex road spirals suggested to get traffic up to f.ex. H.C.Andersens Boulevard looked like something from Chicago and visually would never be accepted in the harbour area of the centre of Copenhagen.

In the end of the day, it doesn't play any vital role, if the tunnel runs under the soil of Amager or under the harbour water.

I finally found the time to dig into some of the planning about the Havnetunnel/Østre Omfartsvej. Maybe I read the wrong newspapers but so far I haven't found any mention of the actual proposed route through the city

So here goes, from the Ministry of Transportation ( link):

The majority in the city council has indicated that they prefer proposal B4 from Hans Knudsens Plads to Nordhavn, Margretheholm, under Kløvermarken, Amagerbro, Ørestad Nord, Amager Fælled and finally the existing highway at Vejlands Allé.

I can't find any proper mention of whether they are heading for the fully drilled tunnel or a tunnel where some parts of the tunnel are cut-and-cover.

"Hovedalternativ 1, linjeføring B4, boret tunnel under Amagerbro" seems to be the best possible solution

The route:



The modelled changes to traffic congestion show a clear relief in traffic in the city centre where polution is above acceptable levels a couple of places:


And here is a drawing indicating the limited "damage" to the Amager Fælled park area (tunnel is underground):



Now, let's see if the green parties wake up and agree to move some traffic out of the city center and into the tunnel. This is a tunnel that seems to reduce congestion drastically AND improves the route across the city for those of us living on Amager. I don't even have a car but can vividly imagine the relief a tunnel must be to those people living in the metro-free middle of Amager, Tårnby and Dragør and working in Lyngby, Ballerup, Bagsværd - all places drastically underserved by public transportation.

Nice find.

That is for the politicians to decide.


Just wondering why they didn't examine the possibility of a connection to Ørestad Boulevard next to Grønjordsvej and DR-Byen.

[korbendallas]

It looks to me like they're focusing on getting heavy vehicles hidden away. Perhaps because this is the kind of traffic you can't move to public transport no matter how hard you try.

Regarding the connection to Ørestad Boulevard, it's probably not possible to have a connection so close to Artillerivej. Although why they picked Artillerivej over Ørestads Boulevard boggles the mind.

A few quick remarks from that document.

A submerged tunnel under Knippelsbro is almost impossible because of a safety distance to the metro tunnel on around 11,5 metres that would make the sailing lane through Knippelsbro only 2 metres deep and that is of course hopeless.

They could also split up the tunnel just before the bridge to avoid the sailing lane but then they would have to reconstruct the pillars supporting the bridge and good look with closing Knippelsbro for several months. :-D

Another solution was to build a drilled tunnel but that tunnel would be located so deep underground that no exit ramps would be possible in the inner city.

The price tag of the preferred tunnel under Amagerbro is with a 50% buffer so the real price is around 18-19 billion DKK.

That is not correct. The 50 % added is not just for uncertainties, it is also because not everything is taken into account in the cost estimate. You might actually call it 50 % of additionally costs. This is standard in Danish cost estimates for infrastructure constructions in fase 1. In fase 2 you add 10 % to the cost estimate.

[Never give up]

There is no time scale or financial proposal for this project except for the first stage (Nordhavnsvej/UC) and perhaps the second to the development area in Nordhavn.

One very important thing in the decision that has been taken on where the "Eastern By-pass" should go, is the fact that it also decides all the places where it isn´t going to go.

There were quite a few proposals and variants of these proposals but now these uncertainties about whether you are going to be neighbour to the road, or if you can develop your building site, is over.
This results in planning blight and often means areas of the city look like bomb sites for years and years.
As regards the construction method there are quite a few areas which could be cut and cover or even open cuttings but that can be decided at a later stage.

@ kalaha

Well i was just quoting the report so maybe i was not specific enough, of course the price is a estimate of the total price.

Quote from the city's homepage:

"Copenhagen Carbon Neutral 2025

Copenhagen will become the first carbon neutral capital by 2025.

Extensive retrofitting of buildings, reorganisation of the energy supply and change in transport habits are some of many initiatives the City of Copenhagen will implement in order to become carbon neutral by 2025.

Borgmester: Havnetunnel vil drøne ind i fredet område
Amager Bladet | 20.11.2012 | Side 18 | 550 ord | Artikel-id: e385aece | Original artikel
HASTVÆRK. Købenavns teknik-og miljøborgmester Ayfer Baykal ( SF) mener, at overborgmester Frank Jensen gambler med Amagers grønne image, når en kommende havnetunnel skal drøne igennem et fredet område på Amager Fælled.

af JAN JEPPESEN jje@b-l.dk

HELE ØEN: Den københavnske overborgmester Frank Jensen ( S) kommer næppe på julekort med byens teknik-og miljøborgmester Ayfer Baykal ( SF). Hun er vred over, at Frank Jensen er » parat til at ofre Amager Fælled for at få mere plads til bilerne « . Ayfer Baykal uddyber kritikken i en pressemeddelelse, efter torsdagens beslutning i borgerrepræsentationen om at udskyde om linjeføringen for at få mere tid til at sætte sig ind i forslaget.
» Frank Jensen har forsøgt at sælge forslaget om en havnetunnel som en østlig omfartsvej.
Han har argumenteret for, at havnetunnellen vil være til gavn for byen og miljøet. Men han har holdt konsekvenserne skjult. Nu står det klart, at han er parat til at ofre Amager Fælled. Det er helt uacceptabelt for SF, og vi har ikke brug for en tænkepause. Forslaget skal helt af bordet, « siger Ayfer Baykal.
Som omtalt i Amager Bladet har Økonimiudvalget i Københavns Kommune givet grønt lys til Transportministeriets linjeføring, men ifølge Ayfer Baykal fik politikerne præsenteret et kort, som var svært at tyde.
Det fik Ayfer Baykal til at stille en byge af spørgsmål om havnetunnelens placering, konsekvenser og fravalgte alternativer.
Men først dagen før, at borgerrepræsentationen skulle behandle sagen om havnetunnellen, fik de adgang til alle oplysninger om den valgte linjeføring.

Konsekvenser for Amager
» Jeg er stærkt utilfreds med, at vi er blevet bedt om at tage stilling til så vigtig sag på så tyndt et grundlag. Jeg har haft mine bange anelser om, at noget var galt, og derfor har jeg gjort meget for at få sagen bedre oplyst.
Nu er mine bange anelser desværre blevet bekræftet. Og jeg står uforstående overfor, at man overhovedet kan overveje at gøre det her mod København og københavnerne, « siger Ayfer Baykal, der også er kritisk over » den manglende fokus på konsekvenserne for biltrafikken på Amager « : » Det skabte en voldsom ballade hos de borgerlige partier i borgerrepræsentationen, da jeg fik penge til at renovere Amagerbrogade. Dengang bekymrede de sig meget for den stigning i trafikken, der ville komme nogle steder. Men de samme partier er parate til at lade trafikken stige massivt på flere gader som Artillerivej og Amager Strandvej, « siger Ayfer Baykal, og opfordrer Frank Jensen til helt at skrotte planerne om en havnetunnel.

Ser frem til valgkampen
Heller ikke Enhedslisten er begejstret for risikoen for, at der bygges en havnetunnel.
» Ved at bygge en havnetunnel får man flere biler i byen.
Der har aldrig været en vej i verdenshistorien, som ikke har givet mere trafik « , forklarer Morten Kabell, der repræsenterer partiet i borgerrepræsentationen, til Politiken. dk I stedet efterlyser partiet en større satsning på at gøre Københavns cykeltrafik og kollektiv trafik mere attraktiv i stedet for at gøre det lettere og mere tillokkende at køre i bil gennem byen.
» Gør man det sværere at køre i bil, så tager man kun bilen, når det er allermest nødvendigt « , siger han.
Amager Fælled er fredet og beskyttet af den politiske aftale om Ørestadsbyggerierne, der tilsagde, at der efter inddragelsen af de grønne områder til Ørestaden skulle der ikke bygges mere.
» Der vil være en fredning, som jeg ikke ved, hvordan overborgmesteren vil komme ud over.
Hvis Frank Jensens plan er at ofre Københavns grønne områder for at føre en motorvej gennem byen, så vil jeg glæde mig til at møde ham til næste års kommunalvalg « , lyder reaktionen fra Morten Kabell til Politiken. dk.

An article on ing.dk:
Københavnerne kommer i anden række til havnetunnel til 27 milliarder kroner

[Hafnia]

The politicians at the cityhall has yesterday adopted the tunnel plan recommended by the Transportministeriet means the 'Amager-solution'
A great decision, however now only the financeing is missing: 27000000000 dkr....
Hope our tiny country can afford it..
