Document Description
The proposed New Irvington Tunnel project would be ~3.5 miles long, extending west from the new Alameda West Portal on the west side of the Sunol Valley to the new Irvington Portal in the City of Fremont. The new tunnel would be located south and approximately parallel to the existing tunnel, seperated by a distance of ~100 to 700 ft from the existing tunnel. The final internal diameter of the tunnel would be between 8.5 and 10.5 ft. The depth of the tunnel would range from ~30 ft below ground surface at the portals to 700 ft below the techniques. The purpose of this project is to construct a new tunnel that would: 1) be built using modern eathrquake engineering designs, materialsm and technology resulting in more resistance to damage during major seismic events; 2) allow the SFPUC to take the existing tunnel out of service for inspection, maintenance, and repairs; and 3) improve overall system delivery reliability by providing a redundant tunnel in the event of a major seismic event or other impact on the existing tunnel requiring maintenance and/or repair.
