China/Transport/National Highways

中华人民共和国国道是指具有全国政治、经济意义并由交通部规划的干线公路。国道按技术等级分为国家高速公路与普通国道两个系统，编号均以G开头。由于早期只有普通国道系统，而后来出现的国家高速公路的名称中也不含“国道”，所以习惯上若无特别强调，所说的国道通常特指三位数字编号的普通国道。本条目也主要讲述普通国道。

中国国道采用数字编号，数字编号前加字母“G”（“国道”的“国”字汉语拼音首字母）。中国国道包括普通国道（三位数字编号）与国家高速公路（一位、二位、四位编号）。

• 编号都是三位数字，分为四类，一类是放射状的，这些公路排序都是“1”开头；第二类是南北向的，以“2”开头；第三类是东西向的，以“3”开头，第四类是“五纵七横”主干线，以“0”开头。
• 放射状国道以首都北京为中心向四周辐射。
• 国道的称谓，如国道319，通常称“G319”、“319国道”或“319线”。
• 2008年起，原先以“0”开头的『五纵七横』主干线被统编入中国国家高速公路网，原有编号不再使用。
• 2013年起，调整和新增一批国道，包括新增一类以“5”开头的联络线。

The China National Highways (国道) are a series of trunk roads throughout all of mainland China. Although they are called highways, they are not necessarily expressways. However, like expressways, a toll is sometimes charged. Nationwide national highways begin with the letter G, followed by three numerals, e.g.: G107. It is said that the G stands for 国家 (guójiā), or national. These are sometime tagged as 'trunk', being the most important inter-provincial roads , or when superceded by expressways, as primary or secondary.

The numbering of the highways is as follows:

• Five vertical and seven horizontal main routes are labelled in the 000 series (the so called "five downs and seven acrosses").
• Except for China National Highway 112, which originates in Tianjin, all highways in the 100 series (e.g. 102, 106) begin from Beijing, the capital city of the People's Republic of China, and spread out in all compass directions;
• Highways in the 200 series stretch from north to south;
• Highways in the 300 series stretch from west to east (e.g., from Lhasa in Tibet through to Dandong in Liaoning province).
