The Haryana Forest Department Corporation (HFDC) will give a green touch to the Delhi portion of NH 8 that falls between Dhaula Kuan and RTR Marg flyover.
The upgrade, which will also cover NH 1 between Karnal Bypass and Singhu Border, will add ornamental grass, flowering shrubs and trees.
The Rs 7.25-crore project, awarded by the National Highway Authority of India has to be completed over the next three months.
About four-five feet-high Gulmohar, Champa, Amaltas and Palm trees will also be planted.
The total number of such trees is expected to be 3,800.
Subhash Yadav, HFDC regional manager, said that the ground work on the project was kicked off even before the Commonwealth Games began.
“We have already started work at the Radisson Hotel roundabout (triangle) that connects Gurgaon Expressway with the Indira Gandhi Intern-ational Airport,” he added.
Earlier, the HFDC planted trees in Aya Nagar and Jonapur in the Mehrauli region.
Yadav said that the firm bagged the R1.15-crore Jonapur project from the UN Environmental Program during the Games.
