The project involves two parallel tunnels, each around 5.30 km long and designed with three lanes
The first tunnel boring machine, Tulsi, became operational on August 17, 2026. Since then, it has completed 183 metres of excavation at an average rate of 5.5 metres per day, according to the BMC
Construction of 87 permanent ring segments, which form an important part of the tunnel structure, has also been completed. In addition, six temporary ring segments have been installed
