Rai’s statement followed the lifting of GRAP 4 in Delhi amid better air quality. The Commission for Air Quality Management (CAQM) lifted restrictions, allowing trucks and buses (except BS-3 and BS-4 petrol and diesel vehicles) into the city and resuming ongoing construction activities.

Rai noted that though there has been a consistent improvement in air quality, people still need to remain vigilant to maintain this improvement. He further added that over the last two days, there has been a steady improvement in pollution levels.

Regarding vehicle restrictions, Rai explained that the ban on entry of trucks has been lifted, except for BS3 petrol and BS4 diesel vehicles. Restrictions apply solely to vehicles above BS 4. He also mentioned the resumption of previously halted linear projects.

Listing areas for resumed construction, Rai included railway and metro stations, airports, international bus terminals, national security-related projects, significant national projects, hospitals, linear projects, and cleanliness projects, ANI reported.
