Roadheader breaks through for final hole-through on October 8th
On October 8, 2013 at precisely 9:00 a.m. two crews of
miners from the New Irvington Tunnel project met underground with their
roadheader digging away at the last final feet of rock. Miners celebrated the final hole-through
excavation of the 18,660 foot tunnel. The
3.5 mile New Irvington Tunnel will transmit water between the Sunol Valley and
Fremont to our 2.6 million Bay Area customers. Work is still not quite done
yet, our miners will prepare the new tunnel for installation of 8.5 ft diameter
steel pipe, installed in 50-foot sections and welded together inside of the
tunnel. This will be followed by the
placement of cellular concrete between the steel pipe and tunnel wall to
complete the project in mid-2015.
