How Engineers Build Impossible Roads on Vertical Cliffs | Mega Construction Documentary

Описание: How do engineers build massive roads on near-vertical cliffs | Mega Construction Documentary at 4,500 meters above sea level? In this mega construction documentary, we take you deep into the Andes Mountains of South America where humanity is engaged in a direct confrontation with some of the harshest terrain on the planet.

Watch as engineers split sheer cliff faces, suspend roads on concrete columns over thousand-meter drops, and bore tunnels through solid mountain rock using 3,000-ton Tunnel Boring Machines.

From precision rock removal and slope stabilization to elevated road construction and TBM tunnel boring, this documentary covers the complete process of how impossible mountain roads are built from start to finish.
