In a bid to scrub Delhi’s air of road dust, the Public Works Department is set to transform four stretches into ‘model roads’ that officials claim will be entirely dust-free. The pilot project is part of a larger plan to redevelop 160 kilometres of the Public Works Department (PWD) road network this year to combat air pollution. According to officials, four specific roads will be identified for comprehensive work, including pothole repair, wall-to-wall paving and greenery. Earlier this month, Chief Minister Rekha Gupta chaired a high-level review meeting to discuss measures for controlling air pollution and road dust. This includes around 800 kilometres under the PWD, 1,200 kilometres under the Municipal Corporation and nearly 1,000 kilometres in unauthorised colonies.
