In addition, Caltrans is notifying recreational boaters and commercial vessels of a waterway closure from 8 p.m. November 14 through to March 3, 2023. Under this temporary deviation issued by the U.S. Coast Guard, the lift span of the bridge will open on signal if at least four hours notice is given to the draw tender.

Work is scheduled as listed but subject to change due to traffic incidents, weather, availability of equipment and/ or materials, and other construction-related issues. Caltrans will issue construction updates on Twitter @CaltransDist3 and on Facebook at CaltransDistrict3.
