Cykelslangen

Hvor Bryggebroen stopper på Københavnersiden tager Cykelslangen over i et legende, slynget forløb, der fører cyklisterne over det indre havnebassin og pladserne langs kajen til Kalvebod Brygge.

Den lange bro er med sit slyngede forløb et interessant objekt i området, hvor den på bedste vis adskiller de cyklende fra de gående. En tur for cyklisterne, som giver dem fornemmelsen af at bevæge sig hurtigt og effektivt gennem området, samtidigt med at oplevelsen af at køre i 1 sals højde er unik og spændende. De gående kan nu udnytte hele kajområdet ved Fisketorvet.

Cykelslangen bugter sig 6-7 meter over vandoverflanden med en længde på 190 meter samt 30 meters rampe. Broen er udført i stål, som er med til at give den et elegant og slankt udtryk. Kørefladen har en stærk orange farve, som skaber et klart visuelt forløb for cyklisterne.

Med den indbyggede belysning, vil broen om natten være tydeligt oplyst og tryg at færdes på. Ydermere kan den berige området som et lysende visuelt element i natten.

Der er dagligt omkring 12.500 cyklister, der krydser Bryggebroen og området ved Fisketorvet.

Ejeren af Fisketorvet kan udnytte det nu mere rolige område til etablering et rekreativt rum, som kan bruges til længerevarende ophold for brugerne af området. Dette vil på sigt løfte områdets kvalitet. Rampen danner en unik kajoverdækning, der ydermere vil kunne skabe mange muligheder for ophold og aktivitet i store dele af året. 

Konstruktivt er rampen en variation over Bryggebroen med en central, lukket ståldrager - den bærende rygrad - hvorfra dækket udkrages til hver side. Med en beskeden spændvidde på omkring 17 meter holdes konstruktionen slank og vægten nede, så Cykelslangen kan løftes på plads i segmenter. Brodækket er konstruktivt integreret med søjlerne, hvorved lejer udgås.

 

The Bicycle Snake

Background
With the change from commercial harbour activities to residences and retail the Inner Harbour of Copenhagen has undergone a pronounced transformation. As part of this transformation the first stage of a foot- and bicycle connection across the Inner Harbour the Brygge Bridge, Bryggebroen by DISSSING+WEITLING architecture, was opened in 2006 . The first new crossing of the harbour in fifty years. The bridge become a tremendous success not only as a connection between two parts of the city, but also simply as a way to enjoy the views of the harbour, the sensation of being  above water. However heading to or from Bryggebroen on the Eastern side of the Harbour cyclist had to carry their bikes down or up a  full flight of stairs at one end of the quayside.

Cykelslangen, or the ”The Bicycle Snake”, a 230 m long sky bridge which offers a short cut to Bryggebroen was opened in the summer of 2014. Cykelslangen takes off where Bryggebroen ends on the Eastern side of the harbour and continues in a meandering course to Kalvebod Brygge, a major roadway, some 5,5 m above the quay. Cykelslangen is used by 12.500 cyclists daily.

Copenhagen and bicycles
In 2011 the City of Copenhagen published its planning strategy for becoming the world’s best bicycle town in 2015. And this for all sort of good reasons – promoting a healthier life style cycling to work, setting the goal for Copenhagen as a CO2 neutral city by 2025, and simply – Copenhagen as a better place to live, more space, less noise, cleaner air. In 2010 with a 36% market share bicycles were the most used means of transportation to and from work within the city. The city’s strategy aims  for 50% by the end of 2015.

In 2010 as part of the city’s bicycle policy,  a forerunner for the bicycle strategy, a series of initiatives were taken. Amongst these a general consultant tender for what was to become the bicycle bridge Cykelslangen.  DISSSING+WEITLING architecture won the tender with Rambøll as sub consulting engineers.

Pushing the boundaries – a specific typology
The clients brief called for a somewhat minimal bicycle ramp providing an alternative to the staircase.  We saw a tremendous potential for the new ramp to become something more than just replacing the staircase. To unfold the ramp from the corner site of the staircase, stretch it out, curve it. Across the water, in between the buildings, and down close to the Brygge Bridge. A clear pathway. Hereby not only making it more joyful to ride on, with less steep gradients and better curvature, but also making it an element that could pull together an area  with a multitude of incoherent buildings.

We proposed a series of alternatives and discussed them with the client, the City of Copenhagen. And the city listened and contributed to the idea. The city’s project manager brought it up higher in the administration. The budget had to be raised and a dialogue with neighbours to be commenced. Not only did it go through, the city also awarded DISSSING+WEITLING architecture, a year before the bridge was opened, for raising the bar. An award the City Administration has established to further good ideas.

Structure
The bridge is a painted, airtight welded steel structure, carried by a central steel spine – a 75 cm box girder, from which a series of cantilevered  struts, made of  folded steel plates, carries the steel plate deck. We aimed for a slim structure, with all parts being structural, hereby reducing the visual impact. We have strived for transparency and simplicity. Structural refinement. The parapet is conceived as a transparent film, no modular hierarchy. In essence underlining the fluidity of movement through space. Celebrating bike riding. Looking out and being seen. The parapet consists of inward leaning steel bars with a circular cross section with a stainless steel handrail.

The bridge relates essentially to Bryggebroen but differs in detail, reflecting its functionality, alignment and setting.

Pavement & lighting
The anti-slip pavement consists of a granulated stone on an acrylic compound. The bridge is lit from LED strip lighting built into the parapet handrail. The thin vertical post are backlit at night highlighting the winding path. 

Cykelslangen – a winding course
The project went from a ramp to an elevated bicycle route. It winds its way and by doing so it makes the bikers inadvertently slow down. A bike route above land and water. And it barely touches either resting on slim columns with a distance of 17 – 20 m. It epitomizes the image of Copenhagen as a bicycle City. The pure joy of cycling. It is orange. Orange so that it may hold its own elevated place amidst the surroundings. Orange to provide a sense of sensuous  luxury. Orange to give it warmth in daytime and at night lit up from the LED strips in the glimmering stainless steel handrails.

Cykelslangen is not an elevated bicycle route. It is not an attempt to establish elevated bicycle routes as such, to separate cyclist from the ground level. Bicycles should not be isolated from but rather be an integrated part of city life, street life. Cykelslangen is a specific answer to a specific problem in Copenhagen.

Awards
In 2013 DISSING+WEITLING architecture was presented with the “Raise the Bar” prize from the municipality of Copenhagen, given for the initiative to promote an idea, which reached beyond the assigned brief. In 2014 Cykelslangen won the WAN Transport Award. The judges all recognized the elegance and ingenuity of the design and felt the architects had responded well to the challenges of the brief. The Bicycle Snake: “An elevated (literally and figuratively) response to a simple problem; adapted to local culture. Simple. Elegant. Joyous.”
