Introduction of Road median width in India as per IRC

India is a country known for its vast road network connecting various parts of the nation. In recent years, there has been a growing concern over road safety and the need to ensure better traffic management on Indian roads. To address this issue, the Indian Road Congress (IRC) has introduced guidelines for the width of road medians in India. This article will provide an overview of the introduction of road median width in India as per the IRC, highlighting its importance and potential impact on road safety.

Road median width plays a crucial role in ensuring the safety and smooth flow of traffic on roads in India. The Indian Roads Congress (IRC) has developed guidelines for the design and width of medians to be followed in the construction of roads across the country.

The median is the physical barrier or space separating the opposite lanes of a road. It can be made of various materials such as concrete, grass, or trees, and its width can vary depending on the type and location of the road.

According to the IRC’s guidelines, the median width for expressways and national highways should be a minimum of 10 meters. This wider width allows for the safe placement of barriers, utilities, and vegetation, providing a visual separation between the opposite flow of traffic and reducing the risk of crashes due to distractions.

For urban roads with high traffic volume, a minimum median width of 8 meters is recommended. This width allows for the safe placement of street furniture, landscaping, and pedestrian crossings.

In case of dual-carriageway roads, the median width varies according to the type of the road. For a four-lane dual-carriageway, a median width of 5 meters is recommended, while for a six-lane dual-carriageway, the median width should be a minimum of 10 meters.

In rural areas or on roads with low traffic volume, the median width can be reduced to 2 meters. However, in such cases, it is essential to have a physical barrier in place for the safety of road users.

Apart from the width, the IRC also recommends having a minimum height of 0.75 meters for the median barrier, if provided. This height ensures that the barrier is visible to drivers, preventing accidents due to sudden lane changes.

In addition to safety, the median width also plays a vital role in the aesthetic appeal of the road. A well-designed median with appropriate width can enhance the overall appearance of the road and make it more visually appealing for the users.

In conclusion, the IRC guidelines for median width in India aim to provide a safe and efficient road network for all road users. The recommended widths are based on extensive research and are regularly updated to keep up with changing traffic and safety requirements. It is crucial for road engineers and designers to follow these guidelines to ensure the construction of safe and sustainable roads in India.


In conclusion, the introduction of road median width in India as per IRC guidelines is a significant step towards improving the safety and efficiency of Indian roadways. The adoption of standardized median width will help reduce the number of road accidents, ease traffic congestion, and provide better pedestrian facilities. The guidelines set by IRC take into consideration the local conditions and factors such as road type, location, and traffic volume, making it feasible for implementation across the country. It is crucial for the government, road authorities, and citizens to work together to ensure the successful implementation of these guidelines, resulting in a safer and more organized road network in India. With the proper execution of these guidelines, we can strive towards achieving a better transportation system for the country.
