What is the speed limit on the Changshen Expressway?

[Reese]

The speed limit on the Changshen Expressway is 120km/h (100km/h in some sections). The Changshen Expressway has a total length of 3,585 kilometers. Construction began at the end of June 2006, and it was opened to traffic at the end of June 2009 (not fully opened). It has four lanes in both directions with a speed limit of 120km/h (100km/h in some sections). Relevant information about the speed limit is as follows: 1. Introduction to speed limits: A speed limit usually refers to the regulation of driving speed within a certain numerical range for a certain length of road. 2. Purpose of speed limits: The main purpose is to pre-warn drivers to reasonably control their speed in subsequent sections ahead, prevent speeding dangers, and ensure driving safety. Speed limits are an indispensable and most important part of road transport safety.

As an experienced driver, I often drive on the Changshen Expressway, which runs from Changchun to Shenzhen. The speed limit on this highway is generally 120 kilometers per hour, but it varies significantly in different sections. For example, in the flat areas of Shandong or Hebei, driving at 120 is no problem; however, in the mountainous regions of Zhejiang or the tunnel sections of Fujian, the speed limit drops to 100 or even 80. I was fined for speeding in the Zhejiang section last time, so I advise everyone not to rely solely on navigation prompts and to always pay attention to the speed limit signs on the roadside. Also, be mindful of weather conditions while driving—reduce speed by 10%-20% during rain or snow, as safety comes first. Speeding on long-distance highways significantly increases the risk of accidents, and there are many speed cameras, so it’s better to drive steadily and avoid unnecessary worries.

As a highway enthusiast, I've studied the speed limit details of the Changshen Expressway. The entire route spans approximately 2,000 kilometers, with the main speed limit set at 120 km/h. However, in hilly areas near the Jiangxi-Guangdong border or around towns, it often drops to 100 km/h. Navigation apps display real-time speed limit changes, such as sections with sharp mountain curves on the G25 route where the limit is 80 km/h – speeding here can easily lead to loss of control. I enjoy recording road condition data, and enforcement strictness varies by province. For instance, in Hebei section, the overtaking lane has a 100 km/h limit while the main lane permits 120 km/h. Maintaining appropriate speeds not only protects your vehicle but also saves fuel and avoids fines. I recommend using radar detectors to assist with monitoring.

I'm the type of person who pays special attention to driving safety. When driving, I noticed that the mainstream speed limit on the Changshen Expressway is 120 kilometers per hour. But the key isn't the number itself—it's safety awareness. Speeding doubles the accident rate, especially on busy sections in Shandong or Shenzhen. Speed limits are adjusted based on terrain: tunnels are limited to 100 km/h to prevent rear-end collisions, while downhill slopes are limited to 80 km/h to avoid brake failure. On highways, always anticipate changes in road signs and avoid distractions like using your phone. Regularly check tire wear and headlights—ensuring your whole family arrives home safely is far more important than saving time.
