On-ramp Closure: Eastbound Mission Blvd. to Northbound I-680

This Thursday night 4/10 and Friday morning 4/11, the Eastbound Mission Blvd. to Northbound I-680 on-ramp in the Warm Springs neighborhood of Fremont will be closed between midnight and 5:00 a.m.

In order to complete essential elements of our regional water pipeline upgrade, it is necessary to close and slightly re-align this on-ramp. This will allow construction activities to continue alongside this busy commuter corridor without further impacting traffic.

Why a Night Time Closure? 
Closing the on-ramp late at night causes the least impact to commuters and local residents.
The pipelines we are upgrading are located directly under the I-680 freeway and the on/off-ramps of Mission Blvd. In order to access the pipeline, a phased traffic handling plan is being put in place. The SFPUC, Caltrans and other governmental agencies have worked together closely on this phased traffic approach plan to limit impacts to drivers and the surrounding community.

Detour Information 
To detour during this five-hour on-ramp closure, use Warm Springs Blvd. (North), and make a right at Auto Mall Parkway to merge onto the I-680 North.

Trucks should take the Warm Springs Blvd. detour or turn left at Durham Rd. to access I-680 before the Mill Creek bridge.

The red line shows on-ramp to be closed at midnight on Thursday night.
The on-ramp will re-open on Friday morning, April 11 at 5:00 a.m., shown in blue.

On the move: huge ball joints head for the fault line

A ball joint secured and ready for transport.

Next week, the first of two massive ball joints will be delivered from storage in Livermore to our construction site in Fremont, where it will be included in the Seismic Upgrade of Bay Division Pipelines Nos.  3&4.

The two identical joints were fabricated specifically for the project. The inner dimension of the ball joints measures 72 inches (6 feet) in diameter. The joint itself measures more than 8 feet in diameter at its widest point. The ball joints are the largest such joints to be used in the Hetch Hetchy Regional Water System, and at the time of fabrication were the largest ball joints in the world.

The joints are made of ductile iron and are part of a system designed to absorb up to 6.5 feet of horizontal displacement if a major earthquake were to take place on the Hayward Fault.

VTA's BART Silicon Valley Extension

VTA's Bay Area Rapid Transit (BART) Silicon Valley Extension Project is a 16-mile extension of the existing BART system to San Jose, Milpitas and Santa Clara, which will be delivered through a phased approach. The first phase, the Berryessa Extension, is a 10-mile, two-station extension, beginning in Fremont south of the future BART Warm Springs Station and proceeding in the former Union Pacific Railroad right-of-way through Milpitas, the location of the first station, and then to the Berryessa area of north San Jose, at the second station. VTA continues project development activities for the second 6-mile phase of the project that includes a 5.1 mile-long subway tunnel through downtown San Jose, and ends at grade in Santa Clara near the Caltrain Station. Construction on the second phase of the project will commence as additional funding is secured.

Building Careers as well as Infrastructure at the Seismic Upgrade of Bay Division Pipelines Nos. 3&4

Through the Cypress Mandela Training Center and Project Build, WSIP is helping apprentices from underserved communities to build their careers while upgrading the Bay Area’s critical water infrastructure. The Seismic Upgrade of BDPL Nos. 3&4 project has consistently supported opportunities for these apprentices.

When labor relations specialist Brian Thomas dropped by Fremont this week, he caught up with DeAndre Washington, an apprentice he helped to place with the job site, and his foreman Lisa Ross, to see how things were going.

DeAndre Washington, Lisa Ross and Brian Thomas

Washington is a graduate of the San Mateo County Project Build program. He grew up in East Palo Alto, and entered Project Build at the age of 21. With the help of his mother, DeAndre and his family moved to Hayward while he learned the construction trade. Having completed a total of 3,200 apprentice hours with 2,600 hours on the Bay Tunnel project and over 600 hours on the Seismic Upgrade project, Ross says that he has made a lasting impression on his current team. Washington has also benefited from the mentorship of Steve P. Rados’ construction team including Jim Pelletier, Tony Ferencik and Jack Beale.

DeAndre Washington prepares a pipe segment with a 
PTFE-coated bottom for sliplining beneath the freeway.

As the SFPUC invests in our critical infrastructure with projects like the Bay Tunnel and the Calaveras Dam Replacement Project, we will continue to provide apprenticeships and opportunities for local and underserved communities.

The Cypress Mandela Training Center is a community based organization dedicated to improving the lives of the people it serves by providing pre-apprentice construction and life skills training along with employment assistance.

Construction Update: Sections of Sound Fencing to Come Down

Due to rainy conditions, the removal of fencing has been postponed. Fencing will be removed in mid-February.


Because the open trench work for both pipelines in the Right of Way has been completed, the contractor will begin removing sound fencing between Nugget Way and Mission Blvd.

Some fencing close to Mission Blvd. will remain until the completion of the project. This flexible sound fencing has significantly reduced noise and dust out of the neighborhood, and will continue to do so for ongoing work areas.

The sound fencing marked with blue lines will be removed.
 Fencing south of the blue lines, as well as north of Nugget 
Way, will remain.
