Built in the 1950's, the San Rafael Creek Bridge has been deamed seismically obsolete. This is the main off-ramp used by thousands of vehicles every day to access downtown San Rafael from Highway 101, northbound. During the summer of 2019, the California Department of Transportation (Caltrans) plans to replace the bridge.
As the lead agency, Caltrans has prepared the plans for this construction and is currently bidding the project. The work consists of removing the existing concrete bridge and installing a new upgraded structure. Replacing the structure will include installing new foundations for the support systems, this will require driving piles. Pile driving is when holes are drilled into soil to provide foundation support.
Survey Options Included:
- 42 nighttime closures with pile driving at night
- 5 full weekend closures (11 PM Friday to 5 AM Monday) with pile driving occurring from 7 AM to 10 PM each day. The first three weekend closures will be consecutive.
- 3 nonconsecutive weekend closures (11 PM Friday to 5 AM Monday) with pile driving around the clock
Construction Bids for this project will be received by Caltrans in mid to late February. The project will be awarded within three months of the bid opening. Caltrans will mobilize in late spring and begin work on the bridge in early summer, 2019.
San Rafael will continue to provide updates about this project as they become available from Caltrans.
