As of September 14, 2013, our miners have tunneled 5,044 feet east from Vargas and 8,758 feet west from Alameda West. In ideal ground conditions, crews have tunneled an average of 130 feet per week. When ground conditions are poor they excavate less than 20 feet. We have 405 feet left to go to hole-through as of September 14, 2013.

New Irvington Tunnel Project Background
The SFPUC is constructing a new 3.5 mile long tunnel to transmit water between the Sunol Valley and Fremont. The New Irvington Tunnel has been excavated from four different tunnel headings. The first two headings met each other in June 2012. This second and final ‘hole-through’ will mark the completion of excavation of the entire 18,660 ft tunnel. Following the hole-through, miners will prepare the tunnel for the installation of 8.5 ft diameter steel pipe, installed in 50-foot sections and welded together inside of the tunnel. This is a major milestone as the final project completion is near!
