Late Night On-Ramp Work Required to Install Temporary Water Pipelines

Night closures of an I-680 on-ramp are required throughout the week of Feb. 25, as crews work to install temporary water pipelines in preparation for the replacement of the Bay Division Pipelines Nos. 3 & 4 (BDPL3&4) regional water delivery pipelines later this spring.The temporary water pipelines will ensure that nearby neighbors continue to have a water supply throughout  construction.
 
During the week of Feb. 25, five-hour on-ramp closures will begin just after midnight and reopen at 5 a.m. in time for the morning commute.

• Tuesday morning, 12:01 a.m. - 5:00 a.m.
• Wednesday morning, 12:01 a.m. - 5:00 a.m.
• Thursday morning, 12:01 a.m. - 5:00 a.m.
• Friday morning, 12:01 a.m. - 5:00 a.m.

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.

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.
