The Bangalore Development Authority (BDA) has called tenders for the short tunnel–rotary flyover project between Hebbal and Mehkri Circle. Karnataka cabinet had approved the project earlier, estimating the cost at ₹2,215 crore. However, BDA revised the plan and cut the cost to ₹1,655 crore as per the tender documents. BDA will fund the entire project from its own budget. The project includes building a 2.25 km tunnel from Hebbal junction, under the flyover and railway line, to the Karnataka Veterinary, Animal and Fisheries Sciences University (KVAFSU). This tunnel, costing ₹1,250 crore, will be constructed using the cut open method, not tunnel boring machines like metro projects. Vehicles exiting the tunnel will join a 1.7 km long flyover leading up to Mehkri Circle. This flyover, costing ₹405 crore, will be a rotary flyover with ramps going up and down towards Yeshwantpur and Jayamahal roads. BDA added two new loops to Hebbal flyover earlier to ease traffic, which shifted congestion to Mehkri Circle. To fix this, BDA first suggested a tunnel, but fears of shifting jams prompted building a flyover too. The project has a two-year deadline. To speed construction, BDA has released separate tenders for the tunnel and flyover, and both will be built at the same time. Details on traffic management and alternative routes, especially for airport travelers, are yet to be announced.
