Document Description
Caltrans proposes replacing a damaged culvert in San Mateo County on SR-84 at post mile 5.00. The culvert crosses under both traffic lanes and begins and ends in existing drainage inlets (DIs). Trenching will be required to remove the existing culvert and replace it with a new one of the same size and length. Some project elements will occur off the paved roadway, but all work will remain within Caltrans right of way (ROW). One-way traffic control will be required during construction. Construction will take place during the summer starting in June 2026.
