Which highway in China has no speed limit?
3 Answers
China's first speed-limit-free highway—the Hangzhou-Shaoxing-Ningbo Expressway—is still under construction. The Hangzhou-Shaoxing-Ningbo Expressway starts at the Xiasha Hub of the Hangzhou Ring Expressway and ends at the Chaiqiao Hub of the Ningbo Chuanshan Port Expressway, with a total length of approximately 161 kilometers. It is expected to be completed and open to traffic before the 2022 Asian Games. Relevant officials stated: Currently, the actual average operating speed on similar expressways in Zhejiang is about 90 kilometers per hour, far below the speed limit of 120 kilometers per hour. Through intelligent systems and vehicle control, the driving speed on the superhighway will be significantly improved. Learning from German technology: Drawing on the technical standards of Germany's speed-limit-free highways and Italy's maximum speed limit of 150 kilometers per hour, the Hangzhou-Shaoxing-Ningbo Expressway has reserved civil engineering technical indicators for a future design speed exceeding 120 kilometers per hour.
To be honest, there are currently no unlimited-speed highways within China. All sections have clear speed limit signs, typically with a maximum speed limit around 120 km/h. As someone who frequently drives for travel and pays attention to road conditions, I believe speed limits are necessary safety measures. China's highways handle heavy traffic volumes, coupled with changing weather and complex road conditions - unrestricted speeds could significantly increase accident risks. From personal experience driving at night, I've noticed numerous speed cameras ensuring strict enforcement for everyone's safety. I recommend using cruise control to maintain steady speeds rather than fantasizing about high-speed racing like on certain German autobahns. Arriving safely is far more important than any thrill. Checking regular traffic updates via official apps for real-time information is also helpful.
From a professional perspective, all highways in China are subject to strict speed limit management without exception. The speed limit system is established based on safety, road conditions, and traffic regulations. For example, although some sections of the Jingzang Highway are long and straight, the speed limit still does not exceed 120 kilometers per hour. I have analyzed the design principles of highways: curves, gradients, and traffic density influence the upper limit of safe speeds. Unlimited speed is impractical in densely populated countries and may lead to high accident rates. When driving, attention should be paid to speed limit signs to avoid speeding fines. It is also recommended to understand highway maintenance mechanisms, such as how tunnel lighting and exit warning systems enhance safety. Developing the habit of using in-car navigation reminders can reduce distractions and ensure a smooth and safe journey.
