GMLR Tunnel Works Mark Milestone With Second TBM Consignment at Goregaon

BMC sets a March 10 lowering date for the first machine, with full tunnelling slated for June 2026 as the launch shaft nears completion.

Overview

  • Excavation of the launching shaft at Film City has reached 23 metres across its full footprint of roughly 200 metres by 50 metres, with about 7 metres remaining.
  • All components for one Tunnel Boring Machine are on site and the final consignment for the second is scheduled to reach the Goregaon yard by Thursday night, officials said.
  • Lowering of the first TBM will begin from March 10, followed by about three months of assembly and gantry installation before boring starts from the Goregaon end in June 2026.
  • The project will deliver twin 5.3 km triple‑lane tunnels—each with an external diameter of about 14.42 metres—within a larger 12.2 km link designed to connect the Western and Eastern Express Highways and reduce travel times.
  • Roughly 1,400–1,500 cubic metres of material are being removed daily using about 120 trucks, as BMC inspections press contractors to hold schedule toward a late‑2028 completion target.
