Upcoming Construction Activities
Beginning midnight on Friday, Feb. 22, an I-680 on-ramp closure is scheduled, as crews need to redirect traffic along this traffic corridor in order to access the water pipeline later this spring.
This closure is necessary for work on a water pipe below the on-ramp. The on-ramp will be closed for five hours, and will reopen on Friday, Feb. 22 at 5 a.m. in time for the morning commute. This time frame has been identified to ensure that work is completed prior to morning commute times. Two additional late night on-ramp closures are required in the coming months to complete this work.
What to Expect?
This night time work will involve some excavation work around the on-ramp area. 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 pipeline in need of replacement is 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. These overnight on-ramp closures are 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.
Traffic 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.
This closure is necessary to complete the temporary bridge installation to ensure that motorists will be able to use this major traffic commute artery at all times. During the environmental review period, this option was identified as being the least disruptive alternative.
