Shiradi Ghat tunnel: Project report suggests drilling, blasting

Drilling, blasting and cutting hill sections are necessary for the construction of the tunnel in the Shiradi Ghat section along with the ‘cut and fill’ method at some sections, a pre-feasibility study on the proposed project has said.

Experts from four Japanese companies, who worked on the ‘Study on Road Improvement Project for Shiradi Ghat Stretch in India’, speak of the risks while advocating the project.

Their expertise has laid the foundation for the detailed project report (DPR) submitted to the Union government.

The report suggested 22.8 km of four-lane connectivity between Gundia and Maranahalli with the project consisting of six tunnels (13.84 km) and five bridges.
