In the wake of the continuous acceleration of urbanization in China, the problems of traffic congestion, environmental pollution and inefficient travel caused by the high-mobility travel mode have gone from bad to worse. In the past few years, under the call of energy conservation and environmental protection and green commuting vigorously advocated by Chinese government, the bike-sharing in China is enjoying wide popularity among the public .However, there are still many issues due to the lack of perfect bicycle road network. This paper describes the construction of a new transportation network by building bicycle viaducts inside the city, to divert motor vehicles from bicycles,improve bicycle speed and ensure the safety and independence of bicycle travel. At the same time, in virtue of the construction of bike viaducts, we hope to achieve the cooperation in "PPP mode" between the government and the bicycle enterprises, mutually apply and manage bicycle elevated road, and provide a low-carbon, safe and fast new way of travel.
