Delhi is preparing for a large-scale road renewal programme that could reshape daily mobility across the Capital once pollution-related restrictions are eased. The city government plans to recarpet nearly 400 kilometres of arterial roads after the Graded Response Action Plan (GRAP) curbs are lifted, signalling a renewed push to tackle long-standing infrastructure gaps that have contributed to traffic congestion and airborne dust.
According to senior officials, funding has already been secured for most of the project. Central assistance has been approved for around 300 kilometres of the proposed road network, while the remaining stretch will be financed directly by the Delhi government. The work is expected to be executed by the Public Works Department, with tenders already finalised to allow immediate mobilisation once construction activity is permitted. The timing of the initiative is closely tied to air quality conditions in the Capital. With Delhi’s air quality index remaining in the “very poor” category and GRAP Stage 3 measures currently in force, construction and demolition activities remain suspended. These restrictions are designed to prevent further dust generation during periods of high pollution, even as they delay much-needed urban maintenance. Urban infrastructure experts say the condition of Delhi’s arterial roads has been a persistent contributor to both congestion and particulate pollution.
Broken surfaces, exposed shoulders and uneven edges often release dust under traffic pressure, worsening local air quality. By rebuilding roads wall-to-wall, the authorities aim to eliminate loose edges that act as constant dust sources. In parallel, the city has been expanding the use of mist spray systems along central verges and medians on major corridors. Officials say these systems are intended to suppress dust particles before they become airborne, complementing the physical rebuilding of road surfaces. While such measures are not a substitute for long-term air quality reform, planners argue they can offer measurable local benefits when combined with better road design and maintenance. The government has indicated that priority will be given to roads built more than five years ago or those that have deteriorated significantly. If conditions allow, the entire recarpeting exercise is expected to be completed within the current financial year, an ambitious timeline that reflects the scale of public frustration with road quality.
From a broader urban perspective, the initiative highlights the intersection between transport infrastructure and environmental management. Well-maintained roads improve traffic flow, reduce vehicle idling and lower dust emissions, supporting more liveable and inclusive cities. As Delhi continues to balance growth with environmental limits, investments in resilient, low-dust infrastructure may prove critical in shaping a cleaner and more equitable urban future.
