The Karnataka State Cabinet has approved the construction of a 16.7-km underground tunnel road, dubbed the North-South Corridor.

Estimated to cost Rs 17,780 crore, the project will be executed in two packages and completed within three years.

The tunnel will feature multiple two to three-lane entry and exit points, improving north-south mobility across the city. 

This high-capacity urban tunnel will link Esteem Mall at Hebbal Junction to Central Silk Board Junction in HSR Layout, aiming to ease chronic traffic congestion. 

Deputy CM D K Shivakumar announced that the government will float a global tender and decide between a hybrid model or build–own–operate–transfer) (BOOT) approach after technical reviews. 

The procurement model will be finalised in coordination with Chief Minister Siddaramaiah.
