The Karnataka government has unveiled plans for the construction of the world’s longest tunnel highway network in Bengaluru. The network will consist of three major corridors spanning a total of 99kms, aiming to alleviate traffic congestion and address land acquisition challenges.

The first corridor, the North-South Corridor, will connect Bellary Road to Hosur Road, passing through key areas such as Yelahanka, Hebbal, Mekhri Circle, Cantonment, Kasturba Road, and Central Silk Board. Additionally, the East-West Corridor will have two sections, one from KR Puram to Goraguntepalya via Old Madras Road and ITPL, and the other from Varthur Kodi to Jnanabharati.

The project will feature three connecting corridors, linking various parts of the tunnel network. Phase 1 will cover 50kms, connecting Hebbal to KR Puram and Cantonment to Silk Board, estimated to cost Rs 22,000 crore. The upper decks of the tunnel road will have separate provisions for two-wheelers, enhancing safety and convenience.

The feasibility study for the project will commence soon. Implementation will take place through a public-private partnership (PPP) model, with the government subsidising the project partially using a hybrid annuity model and recovering investments through tolls. This ambitious initiative aims to decongest Bengaluru’s traffic and provide a more efficient transportation solution, surpassing traditional elevated corridors.
