The excavation of the largest tunnel, 9 km long, for the Kvesheti-Kobi road project has been completed.

The main tunnel was excavated using a Tunnel Boring Machine (TBM) specially designed for the Kvesheti-Kobi project, significantly reducing environmental impact.

The TBM not only drills through the rock but also removes the debris and installs the lining simultaneously.

At 9 km, this tunnel will be the longest in Georgia and one of the most remarkable in the world.
