Karnataka Chief Minister DK Shivakumar has launched Bengaluru's first tunnel road project, a 2.2-km six-lane corridor connecting Hebbal and Mehkri Circle. The ₹1,139-crore project will be completely toll-free and is expected to be completed within 18 months. Designed to ease congestion around Hebbal Junction, the tunnel is part of the effort to address Bengaluru's traffic woes.
