Today’s streets are contested spaces. There seems to be an ongoing, intensifying competition between cars, bikes and pedestrians, trying to get from point A to B as quickly as possible. How do they all share the limited space available in cities?
In the southern Chinese city of Xiamen, a visionary solution to the problem is the Bike Skyway, which enables cyclists to literally soar over cars and pedestrians on the street below. Joining the city’s swooping highway overpasses is the world’s longest elevated bike path. At 7.6 kilometers (4.7 miles) in length and rising five meters (16 feet) above the ground, the Bike Skyway enables cyclists to safely and efficiently traverse the dense core of this city of 4 million people. The skyway runs in a straight line, parallel to the city’s raised bus rapid transit system, with regularly spaced rest areas and multiple access points to reach local businesses, shops and restaurants.
The Bike Skyway was designed by the same Danish architectural firm, DISSING+WEITLING, that built Copenhagen’s famous “snake” bike overpass in 2014. In addition to visiting and riding on the Xiamen Bike Skyway this past summer, I recently had the opportunity to interview Steen Savery Trojaborg, managing director of DISSING+WEITLING.
“In Copenhagen, everything evolves on the ground, where you can just hop off your bike and say hello to someone,” says Trojaborg. “But in Asia, with so many people and activities, a lot of things happen at the third-floor level, such as cross walks. You could have these contact points so when you cross the street you have access to the bicycle skyway. You also have connections with a shopping mall and office buildings.”
Imagine a busy stretch of road with several lanes of traffic divided by islands. Then picture using those islands as the foundation on which to build a bike skyway as an alternative to bike lanes along that stretch. The safety aspect alone makes it worth considering.
“When I was first riding my bike [along the Bike Skyway] I heard honking and I would immediately adjust or look for where the cars were. But then I had to tell myself there were three floors below,” says Trojaborg. The network also has a 1.4-meter safety railing running along its edges.
Accessibility was another consideration when designing the Bike Skyway. There are numerous stairs with ramps that run parallel to the steps that bikers can use to push their bikes up to the skyway. There are also elevators and what Trojaborg describes as “mushrooms” – bike paths with a more gradual incline than stairs – that make it easier for users to roll their bikes to the top. (The mushroom description is inspired by the protective rain covers at the top of these paths.)
“We paid a lot of attention to the gradients on all of the ramps,” says Trojaborg. “It was extremely important not to have too steep gradients. Our argument was that basically the skyway should be accessible for everybody.”
When it first opened in 2017, it wasn’t long before the Bike Skyway reached its maximum number of 2,000 riders per hour and 24,000 daily. Since the initial novelty has worn off, those numbers have decreased to about 4,000 riders per day. Unlike bike-crazy cities like Copenhagen, where the bike lanes are jammed during the week and relatively quiet on weekends, Trojaborg says it’s the opposite in Xiamen. Most users are tourists and weekend explorers, rather than people going to work.
The challenge now is to convince more commuters to use the Bike Skyway. Trojaborg is convinced it’s just a matter of time. “You don’t come up with a plan that says from now on we will have designated bike lanes all over the city. You start on a small scale.”
Over time, as more and more residents got accustomed to riding bikes, communities gradually buy into the idea of establishing additional biking infrastructure. “That’s how you reclaim the city,” says Trojaborg.
