San Mateo County - 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.
Please note crews will be removing materials and equipment tomorrow with flaggers assisting.
