Bispeengbuen - a new plan

Yesterday, an article in the Danish newspaper Politken reported that planners and politicians in Copenhagen might have come to a decision on the fate of Bispeengbuen - the section of elevated motorway that runs down the border between Frederiksberg and the Nørrebro district of Copenhagen.

One of several major schemes to improve the road system in the city in the late 1960s and 1970s, Bispeengbuen was planned to reduce delays for traffic coming into the city from suburbs to the north west.

At the south end of the elevated section, at Borups Plads, traffic, heading into the city, drops back down to street level and continues first down Ågade and then on down Åboulevard to the lakes and, if it is through traffic, then on, past the city hall, and down HC Andersens Boulevard to Langebro and across the harbour to Amager.

Between the elevated section and the lakes, the road follows the line of a river that, from the late 16th century, had flowed through low-lying meadows - the Bispeeng or Bishop's Meadow - and brought fresh water in to the lakes. In 1897, the river was dropped down into a covered culvert and it still flows underground below the present traffic.

From the start, the elevated section was controversial as it cuts past and close to apartment buildings on either side - close to windows at second-floor level - and the area underneath is gloomy and generally oppressive. Traffic is fast moving and generates a fair bit of noise and it forms a distinct barrier between the districts on either side.

There has been an ambitious plan to drop the road and its traffic down into a tunnel with the river brought back up to the surface as the main feature of a new linear park. The full and very ambitious plan - for ambitious read expensive - was to extend the tunnel on to take all through traffic underground, to Amager on the south side of the harbour.

There has been talk of a less expensive plan to demolish the elevated section, to bring all traffic back down to street level, which would be cheaper but would not reduce the traffic and would leave the heavy traffic on HC Andersens Boulevard as a barrier between the city centre and the densely-populated inner suburb of Vesterbro.

This latest scheme, a slightly curious compromise, is to demolish half the elevated section. That's not half the length but one side of the elevated section. There are three lanes and a hard shoulder in each direction and the north-bound and city bound sides are on independent structures. With one side removed, traffic in both directions would be on the remaining side but presumably speed limits would be reduced - so, possibly, reducing traffic noise - and the demolished side would be replaced by green areas although it would still be under the shadow of the surviving lanes.

It was suggested in the article that this is considered to have the least impact on the environment for the greatest gain ... the impact of both demolition and new construction are now assessed for any construction project.

There is already a relatively short and narrow section of park on the west side of the highway, just south of Borups Plads, and that is surprisingly quiet - despite alongside the road.

On both sides of the road, housing is densely laid out with very little public green space so it would seem that both the city of Copenhagen and the city of Frederiksberg are keen to proceed. Presumably they feel half the park is better than none although I'm not sure you could argue that half an elevated highway is anywhere near as good as no elevated motorway.

The situation is further complicated because the highway is owned and controlled by the state - as it is part of the national road system - so they would have to approve any work and police in the city may also be in a position to veto plans if they feel that it will have too much of an impact on the movement of traffic through the area.

note:
Given the brouhaha over each new proposal to demolish the elevated section of the motorway, it is only 700 metres overall from the railway bridge to Borups Plads and it takes the traffic over just two major intersections - at Nordre Fasanvej and Borups Allé -  where otherwise there would be cross roads with traffic lights. I'm not implying that the impact of the road is negligible - it has a huge impact on the area - but, back in the 1960s, planners clearly had no idea how many problems and how much expense they were pushing forward half a century with a scheme that, to them, must have seemed rational.

My assumption has been that the motorway was constructed, under pressure from the car and road lobby, as part of a tarmac version of the Finger Plan of the 1940s.

The famous Finger Plan was an attempt to provide control over the expansion of the city, and was based on what were then the relatively-new suburban railway lines that run out from the centre. New housing was to be built close to railway stations and with areas of green between the developments along each railway line .... hence the resemblance to a hand with the city centre as the palm and the railway lines as outstretched fingers.

Then, through the 1950s and 1960s, the number of private cars in Copenhagen increased dramatically and deliveries of goods by road also increased as commercial traffic by rail declined.

I don't know who the traffic planners were in Copenhagen in the 1950s and 1960s but, looking back, they barely appreciated old building or existing communities, and, presumably, looked to LA and, possibly, to the Romania of Nicolae Ceaușescu for inspiration. Their ultimate aim, in their professional lives, seems have been to design a perfect motorway intersection where traffic flowed without any delays.

They wanted to build a motorway down the lakes and when that was thwarted they proposed a massive motorway system that was to be one block back from the outer shore of the lakes - sweeping away the inner districts of Østerbro and Nørrebro - and with new apartment buildings along the edge of the lake - between their new motorway and the lake - that would have formed a series of semi-circular amphitheatres looking across the lakes to the old city. The whole of the inner half of Vesterbro, including the meat market area, and the area of the railway station would have become an enormous interchange of motorways where the only purpose was to keep traffic moving.

We have to be grateful that few of those road schemes were realised but there is also a clear lesson that, however amazing and visionary a major plan for new infrastructure may appear, it can, in solving an immediate problem, create huge problems for future generations to sort out.

it’s 50 years since the last trams ran through the city

Today is an interesting anniversary because it's now fifty years since the tram service in Copenhagen was shut down with the last trams running through the city on 22 April 1972.

The first trams in the city were horse drawn but electric trams were brought in from the 1890s and the first tram routes were established by private companies but in 1911 the city took over the operation of the tram system.

New trams, tram terminals and street furniture for the tram service were then designed by the city architects department.

At one stage the length of the tram routes through and around the city was just under 100 kilometres in total.

the if or when and the how much and why of new islands and tunnels under the sea

This week, politicians in Copenhagen have to agree a budget for the city for the next financial period and the main item on their agenda will, presumably, be discussions about moving to the next stage their ambitious plans to construct a large new island across the entrance to the harbour …. a major engineering project that has been agreed in principle by both the national government and by the city and agreed across most political parties.

Initial plans set the new island immediately beyond and close to the Trekroner Fort - built in the late 18th century to guard the entrance to the harbour - but the most recent drawings published show that it will now be further out into the Sound and will cover a larger area of about 3 square kilometres. There will be a large park along the eastern edge - planned to be larger than the well used and popular Fælledparken on the north side of the city - with homes on the island for 35,000 people and work there for at least 12,000 people although some assessments have suggested that as many as 20,000 new jobs will be created.

But the new  island is not simply the next version of Nordhavn - just larger and further out - but it is also an integral part of an expansion of traffic infrastructure on this side of the city and there will be extensive flood defences on the east or outer side of the island that faces out across the open Sound …. defences that will be an important part of the protection against storm surges that could flood the inner harbour as the climate changes and as sea levels rise.

The name for the new island - Lynetteholm - was, In part, inspired by the shape with a broad curve to the east side - the side facing out across the Sound - and is from the Danish version of the French word lunette and that has been combined with the Norse word holm for a low island that was usually in a river or estuary and was often meadow.

However, Lynette is not a new name in this area of the outer harbour because it was the name of a curved outer fortress built in the Sound in the 1760s that, with large guns set up there, was an important part of outer defences that protected the entrance to the harbour.

One proposal is to extend the metro to the island from the recently-opened metro line to Nordhavn and that link, from Nordhavn to Lynetteholm through a tunnel uner the entrance to the inner harbour, could be extended on to Refshaleøen and possibly on through to Amager and even on round via the metro stations at DR Byen or Islands Brygge and back to the central railway station. An alternative proposal is for a separate metro line starting from Østerport that would run directly out to Lynetteholm and then continue south to Refshaleøen and Kløverparken and from there to either Amager or to join the existing metro line to the airport from the station at Øresund.

Access to the island for road traffic from the south will be straightforward as the island, in this the most recent version, is now much closer to Refshaleøen and connections could be by a number of short bridges although these would have to allow for the boats with tall masts that would continue to have access to the marina at Margretheholm.

A road connection to Lynetteholm from the north would have to be in a tunnel so that boats could still enter the port without having to navigate under bridges. That road tunnel would start just north of the Svanemølle power station and go under the bay, first to Nordhavn and then on, under the entrance to the harbour, to Lynetteholm.

If that is not enough of a project, then that road tunnel, to get to the island from the north, will, almost certainly, be extended on to form a major new eastern road link.

The preferred option seems to be for a tunnel built just off the east shore of Amager to take traffic from the north around the east side of the city and from Lynetteholm that would link to the existing east-west motorway - Øresundsmotorvejen - for fast and direct access to the airport and to the Øresund bridge. This major road tunnel could be constructed using the same method as the new Femern tunnel that will link Denmark to Germany. There the tunnel will not be cut through below the sea bed but will be constructed as prefabricated sections which will be moved out and lowered into a trench and then covered.

An alternative route for the east road tunnel would cut it along below the present coast or beach road of Amager and again that would form a major road link from the north part of Copenhagen to first Lynetteholm and from there on to the airport and the bridge to Sweden.

There is still a plan for a tunnel to link Nordhavn to Refshaleøen and from there to Islands Brygge, at the top of Amager, that could continue on to Sjællandsbroen. This is not an outer motorway link but more an inner ring road to serve Amager that would take road traffic in and out of the area so for traffic to get either to the north to Hellerup and the coast road or to Helsingørmotorvejen and south to Sjællandsbroen and from there to the south side of the city and out to the west.

Discussions about the infrastructure for road traffic on the east side of the city has resurrected that old but still unresolved problem of Bispeengbuen … a section of elevated motorway, that brings traffic into the city from the north west. It now needs extensive and very expensive repairs and it has been argued that, rather than repairing or replacing an elevated road that cuts through and divides a residential area, through traffic could also be taken down into a tunnel and if that tunnel was extended south then it would remove much of the heavy traffic on HC Andersens Boulevard and all through traffic that now uses Langebro to cross the harbour to get to and from Amager.

Together … major work on storm protection; a large new island for housing; a new east motorway to take road traffic around the city, rather than allowing it to come through the city, and the possible permutations for at least three different routes for new metro lines around the south side of Copenhagen … this is a major and relatively long programme for major engineering and construction work in the city that will not be completed until 2070.

An extension of the metro is the easiest part to justify because that would have clear and obvious benefits for the city itself - building rationally on the success of the new inner ring of the metro that opened a year ago.

However, an obvious problem is the cost of these major projects although it makes sense to complete them together and the state will, presumably, contribute to the cost of the road tunnels that are part of a national road system.

But will fast road tunnels taking traffic under or around the city not just deal with current traffic congestion but actually attract more traffic to city roads? It has been shown in other cities that if new ring roads make it quick and easy to get around a city they also make it quicker and easier to get to and into the city. For the sake of the environment, road traffic has to be reduced … not simply shunted past the city as fast as possible.

① road link and tunnel to Nordhavn - north of Svanemølle and south of Hellerup
② tunnel to link Nordhavn to Lynetteholm and then on to the bridge to Sweden
③ alternative route for a traffic tunnel below the coast road of Amager
④ route for tunnel from Nordhavn to Sjællandsbroen - bridge over the harbour

⑤ if the elevated motorway at Bispeengbuen is demolished then there is a plan
to construct a road tunnel from Fuglebakken to Amager - including a tunnel
under Åboulevard and under HC Andersens Boulevard and on under the
harbour and possibly as far as Artilerivej

 

There is also an important social problem that has to be addressed because, until now, the construction of the metro has been financed from the sale of new land for new developments around the harbour and so Copenhagen appears to have gained both housing and a metro system with little or no financial demand on the citizens but the final return, realised from any development of the land, has to cover not only the cost of claiming the land from the sea and the building costs but also has to generate enough additional profit to pay for the metro.

In Ørestad - the first stage where land was sold to fund the construction of the metro - developers built large and prestigious commercial properties and a mixture of housing including what appears to be a large proportion of social housing. In the later developments, around the south harbour and in Nordhavn, there is still a proportion of social housing but developers have built much more expensive and therefore more exclusive housing to generate an appropriate return. This appears to have skewed the cost of land and housing in the rest of the city so, even with social housing in each scheme, not only are low-paid families excluded from these prime areas along the harbour but they are also being forced out of inner city areas like Vesterbro as prices there have also risen.

This has, to put it bluntly, created middle-class ghettoes that undermine what is perhaps the strongest quality of the city … it’s sense of being a dynamic and tightly-packed community with a strong awareness that everyone should have equal access to what the city has to offer.

Potentially, there is also a problem with the logic of what appears to be a circular argument to justify linking together these major schemes.

Actually, an island is not needed for coastal storm defences. It is one option but the city could build a flood barrier across the harbour without a new island. You have to have an island for the large number of houses that are needed to finance an extension to the metro not just to the island but across a wider area of the city and if you build the housing then it follows that you have to have that metro link and if you construct a metro tunnel then the best place to put all that earth is out in the sea to build a new island so how do you justify an island? …. well either as somewhere to put the soil or as somewhere to put the housing to house the people attracted to live in that new housing by the fast metro link. It does begin to sound like a very complicated Danish version of the nursery rhyme about an old woman who swallowed a fly.

And, to throw another spanner in the works, Copenhagen is an absolutely amazing city … one of the best cities in the World …. but that, in and of itself, is not an argument that the city can or should grow and grow.

In so many ways, it is a fantastic place to live and it works as a city because, although it is a capital city, it is relatively compact and being densely occupied is actually its strength - not its weakness.

It could be claimed that, in terms of lifestyle and infrastructure, it is an ideal model for small and middle-sized cities around the World. For many reasons it cannot be a model or suggest solutions to all the horrendous problems of the mega cities of the World.

Perhaps now politicians - both in the city and nationally - have to address a more interesting and more difficult conundrum. Should or could the growth of Copenhagen be gently but firmly constrained? Is it now time to focus on making Odense and Aarhus larger and equally attractive and popular centres for city life in Denmark?

The government will argue that they have already tried to achieve this by moving out government departments and government jobs but, if that failed, it simply means new incentives have to be tried rather than abandoning the idea and leaving Copenhagen to grow and grow.

A pattern of strong and semi-autonomous cities as regional centres - even in a relatively small country like Denmark - is a rational way to cope with population growth and to cope with the trend world-wide for people to move from the countryside and into cities. According to the UN, by 2050 about 70% of the population of the World will live in “large” cities.

Should Copenhagen really continue to grow by 10,000 new citizens a year?

If so, then yes a large new island is one solution. If not then other questions have to be asked and different problems tackled.

can Lynetteholm - the new island - be car free?

A recent article in the newspaper Politiken has suggested that the proposed development of Lynetteholm, on a new island to be constructed across the entrance to the harbour, will not be designed to be car free even though the initial plans include good links by public transport.

A new report has concluded that by making the residential areas completely car free, property and land values would be reduced so the sums do not stack up for the returns required to make the project viable.

The report by the consulting engineers Rambøll and MOE Tetraplan looked at three scenarios for the new island ranging from almost completely car-free (10 to 15 cars per 1,000 inhabitants) through partially car-free (120 to 130 cars) and finally without restrictions imposed so with average car ownership of 250 cars per 1,000 residents.

If the development goes ahead, there would be homes on Lynetteholm for around 35,000 people and jobs for 35,000.

However, this new island is not simply a development for homes and jobs but also plays a complicated part in the construction of a barrier that is necessary to protect the harbour from storm surges and there will also be recreational areas along the new shoreline that will attract people from all over the city.

Initial plans for the island included a link to the metro that would be a 'relatively' straightforward extension of the recently-opened line to Nordhavn but the new report has concluded that a metro line would only generate the level of service required, if there were no cars on the island and if the line was built to complete an arc across Amager so to continue round to the metro station at Christianshavn and then on under the harbour in a new tunnel to the central railway station and that, of course, that would add very considerably to the cost.

The report also suggests that the harbour ferry service, that now terminates at Refshaleøen, should not just be extended to Lynetteholm but, if the area is to be completely free of cars, would have to run every ten minutes rather than every 30 minutes with the present service.

new ferries for the harbour

Copenhagen is to have new, battery-powered, ferries for the regular service up and down the harbour.

Movia, the operating company, have taken delivery of five of the ferries and they are now being put through the last stages of testing before going into regular service and I'm not sure I like them.

Don't get me wrong. They are exactly the right way to go for the environment and it’s impressive technology. After all, they are large vessels that will carry around 90 passengers and they will have to work hard through every day on a 7 kilometre route from Teglhomen to Refshaleøen. Batteries will be completely recharged at night but will be topped up at each end of the route on the brief turn around.

So my objections?

Well there are two but basically they come down to much the same thing. Because they don't sound right and they don't look right so they don't feel right.

I will have to wait until they are in service before I see inside and can judge what they are like for passengers but recently, as I was taking photographs of the CPH container housing at Refshaleøen, one of the new ferries snuck into the dock and snuck seems like the right word.

At first, I thought it was drifting but then it came round the corner of the quay sideways, like a crab, and pulled forward to the ramp with little more than a gentle hum but quite a lot of bubbles. It's going to take some getting used to because I realised then that I like the churning water and the deep throb of the engine you get on the old ferries. Maybe that’s simply because they sound as if they really can take on the weather and the rain and everything that the harbour and the Sound will throw at them. The old ferries are reassuring - not in a comfort blanket way but you know what I mean.

I like standing on the back platform of a ferry as the churn of the water and the sound of the engines drown out any inane chatter around me so, even on a busy day, I can focus on the view and the light over the harbour - from dazzling sun of a good day to the lowering steel grey of an imminent storm - and I suspect I'm going to miss that. For a start, the new ferries do not have an open platform at the back.

And the new ferries look too swish - so sharply angled rather than reassuringly rounded - so stylish but somehow not solid. They don't look as if they were built in a shipyard but as if they were manufactured in a nice clean factory. No obvious plates of heavy metal and rivets from ship builders who know how to build a vessel that would survive most things that could happen at sea … and I know it’s a sheltered harbour but at the north end, around Refshaleøen, it's more open and exposed and more like real sea than the tame and domesticated water at the south end of the harbour.

I have to confess that, of the ferries now in service, I even preferred the older ferries with their steps at the back of the cabin, only marginally less steep than a ladder, with a hefty iron door at the top to get to the back deck and a bulkhead you had to step over rather than the more recent version with fully-glazed patio doors that know you are approaching so open automatically … well at least they did as you moved from inside to outside but with a well disguised button to get from outside on the deck to back inside.

The new ferry I saw 'dropped' its ramp down and even that glided and hovered and it looked narrower and looked light and for some strange reasons, that I don't quite understand, I know I'm going to miss the ramps of the old ferries that drop down onto the pontoon with an almighty clang that makes everyone jump - even hardened commuters who use the ferry twice a day every day - but, somehow, that's a solid and reliable sound.

Basically, the new boats don't sound or look like a workhorse ferry but like a tourist water bus.
