Bengaluru To Have The World’s Longest Tunnel Highway Network; All You Need To Know About It

India is a developing country, constantly on the way to progress. With new motorways being built in many corners of the country, the road network in India is getting stronger every day. The newest addition to this plan is the world’s longest tunnel highway network, which is about to be built in Bengaluru. By significantly enhancing the state’s infrastructure, the Karnataka government is on its way to making history. Bengaluru will soon have the world’s longest tunnel thanks to the government’s plans to construct a 99-kilometre-long tunnel highway. Here’s all you need to know about it:

Bengaluru To Have World’s Longest Tunnel Highway Network

This will be a magnificent elevated tunnel system with three major passageways. The first North-South Corridor will also pass through Yelahanka, Hebbal, Mekhri Circle, Cantonment, Kasturba Road, and the Central Silk Board to connect Bellay with Hosur Road. According to the proposal, the second East-West Corridor will have two additional corridors.  One of these will pass through Old Madras Road from KR Puram to Goraguntepalya via Varthur Kodi, and the other from Varthur Kodi to Jnanabharati.

Three connecting corridors will also be built as part of the tunnel project. One of them will run from St. John Hospital Junction to Agara Road, another from East to West corridors 1 and 2. The third connecting corridor will run from Wheeler’s Road Junction to Kalyannagar on the Outer Ring Road.

This Project Will Cost ₹22,000 Crore To Complete

An estimated ₹22,000 crore will be spent on the project’s 50-kilometre-long first phase. This phase will connect Cantonment with Silk Board and Hebbel with KR Puram. As per the proposed plan for the tunnel highway network, it will have lower and upper decks for each direction. Moreover, a barricaded space will be created on the upper deck for two-wheelers to move in both directions. The project to build a tunnel under Bengaluru will soon begin a feasibility study. 

Thanks to the proposed tunnel project, the dense traffic in the city will be relieved. As per the reports, one kilometre of tunnelling will cost approximately ₹450 crore. The project will be carried out through a public-private partnership (PPP), in which the government will partially subsidise the project through the use of a hybrid annuity model. This massive investment by the government will be recovered through tolls.

This is a massive project that will change the face of road networks in India!
