What is the speed limit on the Shangnan Expressway?
2 Answers
The speed limit on the Shangnan Expressway is 120 km/h. The Shangnan Expressway project starts from the Ningluo Expressway, connecting to the Shangqiu-Zhoukou section of the Shangnan Expressway, and runs southwest through Shangcai, Suiping, Xiping, Wugang, and Fangcheng, ending at Sheqi where it connects with the Lannan Expressway. It links the four cities of Zhoukou, Zhumadian, Pingdingshan, and Nanyang, with a total route length of 190 kilometers, built according to the standard of a four-lane expressway in both directions. Expressway speed limit values: The speed limit on expressways must not exceed 120 km/h, and the speed limit value should be a multiple of 10 km/h. The difference in speed limit values between two adjacent speed limit sections should not exceed 20 km/h. The speed limit signs set on the mainline of highway interchanges, deceleration lanes, and exit ramps should not differ by more than 30 km/h. Speed limit sign design: The design of speed limit signs should be more concise, clear, and aesthetically pleasing. Speed limit signs should be placed at the starting point of the speed limit section and must not be obscured by roadside trees, structures along the route, or other traffic signs. They should be repeated as necessary.
I'm a seasoned driver who frequently travels on the Shangnan Expressway. The speed limit on this highway is generally 120 km/h, but it may vary in different sections, such as dropping to 100 or even 80 in mountainous and curved areas. I remember once driving through a curve where a sign clearly indicated a speed limit of 100, so it's crucial to pay attention to flashing lights as a reminder. Using a mobile navigation app while driving is quite helpful, as it provides real-time updates on speed limit changes, helping to avoid speeding tickets and ensuring safety. Don't rely too much on habit—always keep an eye on roadside signs, as some sections have lower speed limits at night to prevent accidents. Also, slow down in bad weather, as driving too fast on the expressway can easily lead to loss of control. Safety always comes first.
