Karnataka Plans Tunnel Link Connecting Multiple National Highways Entering Bengaluru

The Karnataka government has proposed a peripheral tunnel road to improve connectivity among several national highways entering Bengaluru as part of its overall infrastructure development plan.

The project is one of 12 proposals that have been sent to the Centre for approval, The Hindu reported.

Currently, the state government has proposed two crucial tunnel projects: Hebbal-Silk Board connectivity and KR Puram-Mysuru Road (Nayandahalli) connectivity.
