Highway 84 Emergency Storm Damage Repair
Project Update
Expected Opening Dates
One-way traffic control in late July 2023
Two-way traffic in late October 2023
Our crews have been working tirelessly each day, repairing the slope and constructing a retaining structure on State Route 84 near Woodside. A temporary one-way traffic control will start by July 2023, with the full reopening of SR-84 by Oct. 2023. In March, a landslide damaged a portion of State Route 84 at Portola Road near the town of Woodside. To keep you informed, Caltrans recently participated in a town hall meeting with local and state elected officials. During the meeting, we provided an update on the progress of the work being done on State Route 84. We encourage you to watch the presentation to learn more about the project.
