As the time I am writing this post, the Skyway elevated pathway in Xiamen (China) holds the international record of the longest infrastructure of this kind. Xiamen, as well as most of the largest cities in the world, suffers from excessive road traffic, pollution and noise. China was full of bicycles decades ago, and authorities want to come back to it, at least partly. Indeed, bikes were one of the main treasures every citizen should have for Mao Zedong.
The Skyway was designed by the Danish architecture studio Dissing + Weitling, and constitutes a 7.6 kilometers long and 4.8 meters width wonder for riders. Moreover, it has pedestrian crossings, parking areas for bikes, access ramps and several intermodality stations, where you can get public transport. 30,000 led lights illuminate it.
Riding on it is so impressive that thousands of people use it everyday. From an architecture perspective, it has received awards like the Danish Design Award in the category of Livable Cities in 2019.
