SFPUC Approves Construction of New Irvington Tunnel
The Irvington Tunnel, a crucial 78-year old component of the Hetch Hetchy Water System, will now have a sibling. The San Francisco Public Utilities Commission recently approved the New Irvington Tunnel Project to construct a new 3.5-mi-long tunnel parallel to the existing tunnel between the Sunol Valley south of Highway I-680 and Fremont, California.
Bid advertisement for the New Irvington Tunnel Project was originally scheduled for this week, with bids opening on Thursday, Feb. 25, 2010 with a contract award scheduled for early April 2010. Because of some needed time to complete revisions to the contract documents, the SFPUC says it now expects to advertise for bids later this month or mid-January 2010.
