Typical Segmental Tunnel Ring

These precast pieces of reinforced concrete Construction Formwork are designed to support the earth and resist pressures from the soil, rock, and water that surround the tunnel.

Teams will build a whopping 3,500 rings, or 28,000 individual Tunnel Ring segments, that will line the project’s single tunnel.
Reinforced with steel, each tunnel lining ring weighs in at roughly 132,000 pounds, and a single ring is made up of eight individual concrete segments that are connected by bolts and dowels.
