Beijing’s ever-evolving landscape will soon see a futuristic, double-helix bridge named San Shan Bridge come 2022, when the city hosts the Winter Olympic Games.
Stretching out from across the city to the mountainous region of Zhangjiakou over the river Gui, the infrastructure – translated to “Three Mountains” – is part of the government’s efforts to provide more efficient transportation to the event location for athletes.
Referencing the union of the five continents, just like the interlaced rings of the Olympic logo, the 452-meter-long bridge sees three sets of cross-connected structures that reflects its name. Each of these structures have a maximum span of 95 meters and are supported by high-strength steel cables that crisscross the bridge in an elegantly woven design. To facilitate movement, the bridge will also be separated into transportation and pedestrian sections via two strips of trees and bushes.
Beijing and Vienna-based architecture firm Penda – whose portfolio includes the bamboo pavilion “One with the Birds” for Beijing Design Week 2015 – will work alongside global engineering consultants ARUP on the ambitious task. If ARUP sounds familiar, it is because the prolific firm has taken projects such as the Bill & Melinda Gates Foundation Headquarters in Seattle to completion and are currently working on Apple Campus 2.
However, the San Shan Bridge is but part of a larger city expansion scheme for the Chinese capital. Beijing Horticultural Expo 2019 (a future exhibition hub) and a more extensive transport system (11,700km of metro planned for 2050) will cater to the city’s aspiration of evolving into a supercity – the third largest in the world at that, with more than 21 million people.
