Neighbors Catch up on the New Irvington Tunnel

Thank you to all of the community members who dropped by the New Irvington Tunnel Open House at the Mission Coffee House last week!  It was really great to see you.  For those of you who weren’t able to attend, here are the highlights as shared by the project team.
  • The New Irvington Tunnel Project is currently 95% complete.
  • The steel liner of the tunnel has been installed. We are welding and grouting the space between the tunnel lining and the outside of the tunnel to seal the tunnel off from groundwater intrusion.
  • The 3.5 mile New Irvington Tunnel will be brought into service sometime this fall 2014, allowing us to take the old tunnel out of service for inspection and possible repairs.
  •  Overall project completion is anticipated in fall 2015, soon after we complete site restoration of all of the above ground work.
  • The New Irvington Tunnel runs parallel to the existing tunnel (which was built in 1932)  between the Sunol Valley south of Highway I-680 and Fremont, California. It provides a seismically designed connection between Sierra Nevada and Alameda Watershed water supplies and 2.6 million Bay Area customers.
We will be back out with another open house in a about three months, so we hope you can make the next one.
