- NIT’s Road Header Rendezvous
After 13 months of digging the New Irvington Tunnel from four separate tunnel headings, miners from two of the headings met up with each other underground today. Called a ‘hole-through’ in tunneling terminology, the road header teams from the Irvington Portal in Fremont and the Vargas Shaft 4,500 feet away shook hands somewhere under the mountainside and formally completed this section of tunnel excavation. The New Irvington Tunnel, a critical component of the Hetch Hetchy Regional Water System, will stretch 3.5 miles (18,660-feet) from the Sunol Valley to Fremont, California when it is complete.
