5.3.1 The numbering of national trunk roads consists of the national highway identification code "G" and a three-digit number. The first digit of the digital number is filled with "0" and the starting number interval is 9 to facilitate future expansion. Among them: the north-south longitudinal line starts from the north end of the Lu line and ends at the south end. It is arranged in the longitudinal direction of the route and numbered with even numbers from east to west, such as: C010, G020......
The east-west horizontal line starts from the east end of the route and ends at the west end. It is arranged in the horizontal direction of the route and numbered with odd numbers from north to south, such as: G015G025+*+
5.3.2 The numbering of the national highway radial line is composed of the national highway identification code "G", the radial line identification \1 and the 2-digit sequence number. Starting from Beijing and ending at the end point of the radial line, the numbering is arranged in the clockwise direction of the route. 5.3.3 The numbering of the national highway north-south longitudinal line is composed of the national highway identification code "G", the north-south longitudinal line identification "2" and the 2-digit sequence number. Taking the north end of the skeleton line as the super point and the south end as the end point, it is arranged in the longitudinal direction of the route and numbered from east to west. 5.3.4 The numbering of the east-west horizontal line of the national highway is composed of the national code "G", the east-west horizontal line identifier "3" and a 2-digit sequence number. The east end of the route is the starting point and the west end is the end point. The numbering is arranged horizontally from north to south. 5.3.5 Provincial Road Numbering

6.1 Code structure
The route code is composed of the route number and the Chinese administrative division code. 6.1.1 Highway route code structure:

China administrative division code
Highway route number
6.1.1.1 In route numbering, national highways (including trunk roads) shall be based on the provisions of GB917.2; provincial highway numbering shall refer to the provisions of JT/T307.1; county road numbering shall be based on the provisions of 5.3.6; township roads and special highway numbering shall be based on the provisions of 5.3.7. 6.1.1.2 China's administrative division code shall be the 6-digit code specified in GB/T2260. 7 Other instructions
7.1 Highway route numbers shall be used for identification and exchange of highway information systems and network information, and can also be used for identification of public carriers (such as maps, mileage posts, signboards, etc.).
7.2 Route numbers shall be compiled in accordance with the classification principles and definitions of highway administrative level classification, and branch lines, expressway sections, etc. shall not be used as a route number. The abbreviation of a highway route should be "×X Line" and not "×× Highway". 7.3 The highway ring roads around the capital or provincial capital should be considered as the connecting ring roads of the radial lines of the capital or provincial capital, and should be numbered from the inner ring to the outer ring in the clockwise direction around the city. When two or more discontinuous highway ring roads that have been numbered are finally connected into one ring road, the starting point should be re-determined, and the number of the ring road with a larger number should be invalidated and replaced with the number of the ring road with a smaller number. 7.4 Before the main national highway is connected, temporary numbers can be given to the sections from the starting point to the end point of the route, and attached to the number of the main trunk line. After the entire line is connected, the numbering should be in accordance with the provisions of GB917.2. The temporary numbering of the road section should ensure its uniqueness within the provincial administrative area. 7.5 When the main national highway overlaps with other administrative level highways, they should be numbered separately according to the numbering rules before the road network is adjusted. 7
