Cykelslangen: Copenhagen lifts bikes over pedestrians on a 220m orange bridge

On the Dybbølsbro-to-Bryggebroen link, Copenhagen cyclists had to weave through slow-moving pedestrians, shopping-mall crowds and staircases where they had to dismount and lug bikes up steps. The municipality wanted a cycle connection that matched its ambition to remain the world's leading bike city.

Give cyclists their own elevated route: a slender orange bridge lifts bikes above the pedestrian harbourfront, turning a congested detour into a fast, joyful ride.

Copenhagen Municipality commissioned Dissing+Weitling to build the city's first bike-only bridge, an eight-year project that opened in June 2014. The roughly 220-metre steel Cykelslangen snakes at first-floor level about seven metres above the harbour, curving deliberately so gradients stay gentle, and replaces the awkward shared staircase with a dedicated, sheltered cycle route.

The predicted 12,500 daily users proved conservative when 20,700 riders crossed in a single day in 2015. The bridge ended the pedestrian-cyclist conflict at the site, became an icon of Copenhagen's bike culture, and helped spur further super cycle track projects, including Inderhavnsbroen, which completed the eight-mile Harbour Circle in 2016.

Cykelslangen — 'The Bicycle Snake' — is a bike-only bridge opened in June 2014 in Copenhagen, where more than half of residents commute by bike. It lifts cyclists above a busy waterfront between the Fisketorvet shopping mall and Kalvebod Brygge, where pedestrians, stairs and slow crowds had forced riders to dismount and interrupt their journey.

Planned over eight years by Copenhagen Municipality, the roughly 220-metre steel bridge was designed by Dissing+Weitling and engineered by Ramboll for about 32 million Danish kroner. Its bright orange deck meanders at first-floor level around buildings and above the harbour, curving to keep the gradient rideable, and doubles as a canopy sheltering the walkway below — the city's first bridge reserved exclusively for bicycles.

The idea worked on both counts: it removed the conflict point while making the ride itself pleasant, and the counts followed. The Danish Architecture Center reports that a predicted 12,500 daily users proved conservative when more than 20,700 riders crossed in a single day in 2015. The bridge has since become a symbol of Copenhagen's cycling culture and part of a growing network of 'super cycle tracks' and harbour crossings.

Instead of widening a shared path, it solved the conflict vertically by giving cyclists their own level — separation by design rather than by rule.

The bridge was built to be desired, not just functional: colour, curve and harbour views make the commute itself an argument for cycling.

Curving the route on purpose kept the gradient gentle enough for cargo bikes and families, so the design widened who could use it.

The city treated a junction fix as part of a network ambition, so one bridge seeded further super cycle track projects.

Infrastructure can carry the message: build the fastest and most pleasant route for the behaviour a city wants, and people adopt it without needing to be persuaded.

Cykelslangen became one of Copenhagen's most photographed cycling structures, with the Danish Architecture Center citing a 2015 single-day count of more than 20,700 riders as proof that predicted use was conservative. Its success supported further cycle-bridge projects, including Inderhavnsbroen, which completed the eight-mile Harbour Circle connecting twelve city areas in 2016. The bridge is exhibited as an example of iconic Danish architecture, and Dissing+Weitling cites it in international discussions on infrastructure-as-experience.
