What does G2 National Expressway mean in Subject 1?
4 Answers
G2 National Expressway refers to the Beijing-Shanghai National Expressway. Here is relevant information about national expressways: 1. Introduction: Based on their position in the road network, China's expressways are divided into national expressways and provincial expressways. National expressways are abbreviated as "National Express" and are marked with a red background and white characters on the upper banner; provincial expressways are abbreviated as "Provincial Express" (indicated by the abbreviation of the provincial administrative region on the signage) and are marked with a yellow background and black characters on the upper banner. 2. Precautions: According to the "Expressway Traffic Management Regulations," pedestrians, non-motor vehicles, tractors, agricultural transport vehicles, electric bicycles, wheeled special machinery vehicles, full-trailer tractors, and motor vehicles with a designed maximum speed below 70 kilometers per hour are prohibited from entering expressways.
The G2 national highway mentioned in Subject 1 is actually the unified national numbering for the Beijing-Shanghai Expressway. When I was studying for my driver's license, I also researched this specifically. The 'G' stands for national-level expressway, and the following number is the route code. Generally, the smaller the number, the more important the main route is. For example, G1 is the Beijing-Harbin Expressway, while G2 is the major artery connecting Beijing to Shanghai, spanning over a thousand kilometers. This numbering is prominently displayed on green road signs, and when driving, following the G2 markers ensures you won't go the wrong way. Understanding this coding system is particularly practical, especially for long-distance travel, as it helps quickly determine the importance and direction of the expressway, avoiding hesitation and wasted time in unfamiliar areas. While navigation apps are convenient nowadays, having a grasp of the basics is always beneficial.
I've been in the long-distance transportation industry for over a decade and know the G2 Expressway like the back of my hand. The 'G' in national expressways stands for the initial of 'Guo' (meaning national), while '2' indicates it's the second main artery originating from Beijing—the Beijing-Shanghai Expressway. When actually driving, the numbering helps predict traffic conditions: for instance, the G4 Beijing-Hong Kong-Macao route has heavy traffic, while the G2 is relatively smoother. The numbering system follows specific rules—odd numbers denote north-south routes, even numbers indicate east-west routes, though G2 belongs to the special capital radial lines. I recommend beginners memorize common numbers like the G15 Shenyang-Haikou Expressway and G42 Shanghai-Chengdu Expressway. Combined with the white-letter-on-green-background signage design, this knowledge can significantly improve driving efficiency.
When I was preparing for the written driving test, I memorized the expressway numbering system quite well. G2 specifically refers to the Beijing-Shanghai Expressway, which is a trunk highway uniformly planned by the State Council. These numbers are assigned based on the importance of the route, with G1 to G7 all radiating from Beijing. G2 connects the two major economic zones of the Yangtze River Delta and Beijing-Tianjin-Hebei. The numbers are displayed on green diamond-shaped signs, clearly distinguished from provincial expressways marked with yellow 'S' prefixes. Nowadays, some new expressways use four-digit G-numbers, but the main trunk lines still retain two-digit designations. Actually, remembering the numbers is more reliable than memorizing road names, as different sections may have alternate names.
