The Environment Ministry’s Expert Appraisal Committee has recommended environmental clearance for Phase-III of the eight-lane expressway between Chennai and Bengaluru.

The National Highways Authority of India (NHAI) is responsible for the project, which runs through the Andhra Pradesh districts of Chittoor and the Tamil Nadu districts of Vellore, Ranipet, Kancheepuram, and Tiruvallur.

Andhra Pradesh and Tamil Nadu make up the length. From Ramapuram in Chittoor to Irungattukottai in Sriperumbudur taluk, the alignment stretches for 106.10 km.

The project will improve connectivity between Bengaluru and Chennai, as well as serve as a link between Karnataka’s, Andhra Pradesh’s, and Tamil Nadu’s major commercial and industrial centres.

There will be 31 major bridges, 25 minor bridges, 137 culverts, 13 vehicular underpasses, 5 vehicular overpasses, 3 light vehicle underpasses, 50 pedestrian underpasses, 7 interchanges, 3 road over-bridges, and 6 toll plazas on the route envisaged for phase III. On the recommendation of the Forest Department, an animal underpass has been proposed. Three truck laybys, four rest spaces, and high tower lights are also included in the design.

The NHAI informed the committee that the proposed right of way contains approximately 16,954 non-forest trees and 2,058 forest trees, and pledged to cut trees within the formation width to minimise losses.

In the right of way, about 1,69,540 trees will be planted… The remaining trees will be planted in conjunction with the Forest Service, “it said.

For the NHAI to carry out the project, the Expert Appraisal Committee imposed certain criteria. It stated that green belt development (tree planting) in lieu of trees cut on non-forest property should be done by the State Forest Department as deposit labour rather than by a private contractor. It was mandated that the alignment be maintained in such a way that ancient or historic trees would be preserved.

It stated that all large and small bridges and culverts should not have an impact on drainage systems, among other things. The floodplains of rivers and drainage systems should not be disturbed, and pillars should not be erected on the beds of water bodies when over-bridges are being constructed.
