The BDA has finally got the green signal from the Union environment committee for its eight-lane Peripheral Ring Road (PRR), and now faces the tough task of land acquisition.
The 73.5-km road passes through six lakes and the Thippagondanahalli catchment area.
The Bangalore Development Authority (BDA) had come under fire for gross underestimation of the environmental impact.
Officials had claimed only 200 trees would be cut for the project. The number then went up to 16,685. A revised report last year put the number at 32,175 trees.
