The concrete will be used to form the roadway slab at the portal for the newly mined tunnel.
During the pour, two crews worked while quality control inspectors monitored to ensure proper placement of the concrete.
While this is not the largest pour on the project, crews said the pour is critical to service Mary, the Tunnel Boring Machine, which recently began work again boring a twin eastbound tunnel.
