Why is the speed limit of Gansu Expressway 80?

Avoid potential safety hazards. The speed limit of highway 80 in Gansu Province is limited by natural conditions or influenced by design and construction defects, which has left many hidden dangers for road traffic, such as the northern slope of Wushaoling, deep ditch danger, frequent road icing in snowy days, blurred vision in foggy days and frequent accidents. According to the response of the traffic police department of Gansu Provincial Public Security Department, the frequency of accidents will be reduced after the speed limit.
