An introduction to the width of the red line of the road, and how many meters the range of the red l

The red line of the road is the boundary line of the road width of the planned road, which is the division of urban road land and other urban construction land.

of the demarcation control line. Sometimes a building line that determines the location of buildings along the street is also called a red line, that is, a building red line. Motorized vehicles and non-motorized vehicles.

and the width of the road required for pedestrian traffic; the additional width required for laying underground and above-ground pipelines and urban public facilities; Plant street trees.

The width required.

The range of the red line of the highway is generally 30 meters, and the range of the highway construction control area is the distance from the outer edge of the highway land to the outside: the national highway is not less than 20 meters; Provincial roads are not less than 15 meters; The county road is not less than 10 meters; The country road is not less than 5 meters.

Road red line: It is the boundary line of the road width of the planned road, and the demarcation control line that divides the urban road land and other urban construction land. When there is a reputation, it is also called a red line to determine the location of the buildings along the street, that is, the building red line.

It may coincide with or retreat behind the right line, but it must never go beyond the right line, and no permanent structures are allowed to be built within the red line.

The width between the planned road lines is called the width of the road line, which consists of three parts: the width of the road required for the passage of motor or non-motor vehicles and pedestrians, the additional width required for laying underground and above-ground engineering pipelines and urban utilities, and the width required for planting street trees. The red line of road is the general term for the land used for each component of the road cross-section.

Legal basis

The Regulations on the Protection of Highway Safety have corresponding provisions: Article 6 The competent departments of transportation at or above the county level shall comprehensively consider the relevant national vehicle technical standards, highway use and other factors, and gradually improve the level of construction, management and maintenance of the Qingyanzheng Highway, and strive to meet the needs of national economic and social development and the production and living needs of the people.

Article 7 The competent departments of transportation at or above the county level shall, in accordance with the provisions of the Emergency Response Law of the People's Republic of China, formulate emergency plans for emergencies (hereinafter referred to as highway emergencies) that damage highways such as debris flows, rain, snow and freezing disasters, and implement them after approval by the people at the same level.

Highway management agencies and highway operating enterprises shall, in accordance with the emergency response plan for highway emergencies formulated by the competent departments of transportation, set up emergency response teams and organize emergency drills on a regular basis.

Article 8 The State shall establish and improve the emergency material reserve guarantee system for highway emergencies, improve the emergency material reserve and deployment system, and ensure that the needs of emergency response can be met in the event of a highway emergency.

11th local people at or above the county level shall, in accordance with the principle of ensuring the safety of highway operation and the need for highway development, organize the departments of transportation, land and resources to delineate the scope of highway construction control areas. The scope of the highway construction control area, the distance from the outer edge of the highway land to the outward is as follows:

1) National highway not less than 20 meters;

2) Provincial roads not less than 15 meters;

3) The county road is not less than 10 meters;

4) The village road is not less than 5 meters.

If it belongs to a highway, the scope of the highway construction control area shall not be less than 30 meters from the outer edge of the highway land. The scope of the building control area on the inside of highway curves, interchanges and level intersections shall be determined according to the requirements of safe sight distance.

1. Expressway: The width of a lane on the main road should generally be adopted, and when the central area of the city is dominated by cars, the small lane can be set to; When there are many lanes, a hybrid type can be used. The width of the DAO curb is and the width of the crash walls on both sides is.

1) Gathering and distribution lane: set when the intertwined traffic flow is serious. Generally, it is 7m of dual carriageway.

2) Variable speed lane: It is connected with auxiliary roads and ramps, and should be designed as a single lane.

3) Emergency parking belt: In order to ensure driving safety, the four-lane expressway is generally set up with a continuous or discontinuous emergency parking belt, and a continuous emergency parking belt is set up at 500m when it is not continuous, and a continuous emergency parking belt is generally used on the elevated road. Demolition search.

Second, the main road: also known as the city's main road, mainly connected with the city's main industrial and mining enterprises, the main system of transportation hubs and the city's public places, etc., for the city's main passenger and freight transportation routes, the general red line width of 30-45 meters.

3. Secondary roads: also known as district roads, are auxiliary traffic routes connecting the main roads, and the width of the red line is generally 25-40 meters.

4. Branch roads: also known as neighborhood roads, are the connecting roads between neighborhoods, and the width of the red line is generally 12-15 meters.

The control range of the highway construction area, the distance from the outer edge of the highway land to the outside of the standard is: 1. The national highway is not less than 20 meters; 2. The provincial highway shall not be less than 15 meters; 3. The county road shall not be less than 10 meters; 4. The village road is not less than 5 meters. If it belongs to a highway, the distance from the outer edge of the highway land to the distance standard of the highway construction control area shall not be less than 30 meters.

The control range of the red line on both sides of the highway is based on the center line of the central axis road and the highway.

The control range of the red line on both sides of the highway is based on the center line of the central axis road and the highway. On October 13, 1987, Article 31 of the "Highway Management Regulations" promulgated and implemented stipulates that "the distance between the edge of the building and the outer edge of the highway ditch for the construction of permanent engineering facilities on both sides of the highway shall be:

The national highway shall not be less than 20 meters, the provincial highway shall not be less than 15 meters, the county road shall not be less than 10 meters, and the township road shall not be less than 5 meters" (revised and re-promulgated on December 27, 2008, and the article was changed to Article 29).

Since the Highway Law had not yet been formulated at that time, this provision of the Highway Management Regulations was the earliest provision on the management of highway construction control areas at the level of national laws and regulations.

The width of the red line of the county road is generally **m**.

The width of the red line of a county road is a standard for road design, which includes factors such as lane width, shoulder width, slope slope, pavement structure thickness, and green belt width to ensure road safety, comfort, and convenience. Specifically, the width of the lane of the county road is usually meters to meters, the width of the shoulder is meters to 1 meter, the slope slope is 1 to 1 to 1 ratio, the thickness of the pavement structure is 15 cm to 30 cm, and the width of the green belt is 1 meter to 2 meters.

Of course, these values are not absolutely fixed, and the actual design needs to be adjusted according to local topography, climate, traffic flow and other factors.

Take the width of the lane.

The maximum value of meters, in the absence of ** green belt and divider, the width of 7 meters is a two-way single lane.

70 meters of road width.

There can be up to 10 lanes in both directions, but these 70 meters is the width of the red line, and the width of the red line also includes the widening of the reserved width and sidewalks.

The width, the width of the green belt, and the width of the roadbed, so it is not easy to determine if it is not based on the actual situation, and the difference is very large. But the two-way 6 lanes can still guarantee such a width.

The 70-meter road within the red line is a first-tier city according to national regulations.

The maximum upper limit of the road.
