Highway 84 Emergency Storm Damage Repair

Project Update

State Route 84 at Portola Road, Woodside, Reopens

State Route 84 at Portola Road near the town of Woodside has reopened to two-way traffic. The roadway was closed in March 2023 due to landslides related to major weather events. The 250-foot-wide slide area was significant and made the roadway unusable.

Once the area stabilized, Caltrans was able to begin repairs and eventually open the roadway to one-way signalized traffic control. This allowed access for motorists while giving our crews a safe work area to complete the repairs.

Roadway repairs included:

Repair slope and construct retaining wall
Reconstruct roadway structural section
Repair drainage system(s)
Erosion Control

Caltrans would like to thank the public for their patience and support as we worked together to repair the roadway.

In March 2023, a landslide damaged a portion of State Route 84 at Portola Road near the town of Woodside. To keep you informed, Caltrans 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.
