Project Update: Night Work Required to Complete Temporary Water Pipeline

Upcoming Night-time Work

Closure of an I-680 on-ramp and five hours of night work are necessary on Monday, March 25 beginning just after midnight and continuing until 5 a.m., as crews complete a pipe tie-in that will allow continuous water supply to customers while we upgrade this major water distribution line.

Last month, a water quality testing apparatus was installed to ensure the delivery of high-quality drinking water to Fremont residents and others. As a next step, the contractor will remove the testing apparatus and install another length of pipe.

This five-hour timeframe has been identified to ensure that work is completed prior to morning commute times.

What to Expect?

This night work will involve some excavation around the on-ramp area. In addition, crews will also use a crane to remove the testing apparatus from the ground and to lay the new pipe. Water service will not be interrupted during this process.

The contractor will employ best management practices to control noise, dust and other disturbances around the site.

Why Night Time Work?

The regional water delivery pipelines in need of replacement 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 will be in place. This overnight on-ramp closure is one of a handful of traffic diversions that this project will require along this busy traffic corridor.  The SFPUC, Caltrans and other governmental agencies have been working with the contractor on this phased traffic approach plan.
