FREMONT (BCN) – Construction on a new water pipeline through Fremont is expected to affect commuters for the next couple of months. Crews began work Tuesday morning on the pipeline, starting near Paseo Padre Parkway at Grimmer Boulevard.

It’s a critical component of the Bay Area’s water system, bringing Hetch Hetchy water to 2.5 million people in Alameda, Santa Clara, San Mateo and San Francisco counties.

Crews will work between seven in the morning and seven in the evening laying and welding six-foot diameter steel pipeline. During work hours, only two lanes of traffic will remain open, and motorists should expect delays. If possible, drivers may want to use other routes.

Starting Sunday, crews will begin working at night to install pipeline at Mission Boulevard near Mission San Jose Park. That work is expected to take up to three weeks.
