Future-proofing Infrastructure New Width Standards Set for National Highways in India

In a proactive move aimed at future-proofing India’s transportation infrastructure, the Ministry of Road Transport and Highways (MORTH) has introduced revised width standards for the construction of national highways.

Unlike previous norms, which varied across regions, the new regulations mandate a standardised width of 60 metres for six-lane highways and 45 metres for four-lane highways in all states. This uniform approach ensures consistency and facilitates streamlined development processes, enabling effective implementation of highway projects across the country. By setting clear guidelines for land acquisition requirements, MORTH aims to mitigate challenges associated with varying road widths and enhance the efficiency of highway construction and expansion initiatives. Under the revised norms, both four-lane and six-lane highways must include a 2.5-metre-wide paved shoulder, along with a 1.5-metre-wide earthen shoulder in certain areas. Additionally, the construction of footpaths on bridges and the installation of crash barriers along road sides are now mandatory, further enhancing safety measures and reducing collision risks. In Kerala, ongoing construction work on the six-lane NH 66 exemplifies the adoption of these new standards, with each lane spanning 45 metres and incorporating paved shoulders. However, challenges related to space constraints have prompted authorities to seek concessions from MORTH to ensure compliance with safety regulations.

Despite the absence of storage lanes, which are typically used for vehicles to enter and exit the main road, innovative solutions such as flip roads are being explored to address operational challenges. While traditional approaches may not be feasible due to space limitations, the implementation of warning and sign boards serves to enhance road safety and ensure smooth traffic flow. Overall, the introduction of standardised width norms for national highways marks a significant step towards enhancing India’s transportation infrastructure and promoting sustainable growth. By prioritising safety, efficiency, and future scalability, MORTH aims to create a robust road network that supports the country’s evolving mobility needs and facilitates economic development.
